i need website for advance improvekent onnx models sota Completed 2 steps For advanced ONNX model improvement and SOTA resources, these are the best websites to start with: ONNX Models — a curated hub for finding pre-trained ONNX models, including community, Hugging Face, AMD, and Qualcomm sources. It also points you to Olive for converting, optimizing, and quantizing models. ONNX Runtime model optimizations — the main docs for performance tuning, graph optimizations, and reducing model size/complexity. ONNX GitHub organization — the official ecosystem page for tutorials, the ONNX standard, and the model zoo. ONNX Model Zoo — a collection of pre-trained, state-of-the-art ONNX models. For a more workflow-oriented platform, SOTA by Graiphic describes a unified ONNX Runtime-based environment for optimizing, debugging, and deploying models across hardware targets. If you want, I can narrow this down to: optimization/quantization docs model zoos tools for converting PyTorch to ONNX the best SOTA ONNX deployment stack for your use case https://www.kaggle.com/competitions/neurogolf-2026 The Kaggle competition is The 2026 NeuroGolf Championship, a research prediction competition focused on designing the smallest neural networks to solve ARC-AGI image transformations. It is currently active and has a leaderboard, code, data, rules, and discussion pages on Kaggle. Useful links: Competition overview Leaderboard Data Code Rules The dataset page shows 401 files, about 97.15 MB, and Apache 2.0 licensing, though Kaggle requires you to accept the competition rules before accessing the data.

ONNX Runtime explicitly recommends techniques that reduce model size and complexity, and ONNX Neural Compressor supports accuracy-driven quantization workflows, including SmoothQuant and weight-only quantization. Best techniques INT8 quantization: usually the biggest win for standard vision or MLP-style models, especially when latency and file size both matter. ONNX Runtime has dedicated quantization tooling for this. Weight-only quantization: useful when activation precision is more sensitive, and especially strong for transformer-like or large linear layers. ONNX Neural Compressor supports this directly. SmoothQuant: helps make activation quantization more stable by shifting difficulty into weights; this is one of the better advanced methods when naive INT8 hurts accuracy. Pruning / sparsity: reduces parameter count, but it only helps file size if your runtime or export path can actually exploit sparsity. In practice, it is often more useful for speeding inference than shrinking the ONNX file. Knowledge distillation: train a smaller student model to imitate a larger teacher; this is often the best route when you need a genuinely tiny model rather than just a compressed export. Architecture slimming: reduce hidden width, depth, attention heads, or kernel counts before export; this is often more reliable than trying to compress a model that is already too large. Practical ONNX workflow Export the smallest architecture you can tolerate. Fuse and simplify the graph before quantization. Try post-training INT8 quantization first. If accuracy drops too much, switch to SmoothQuant or selective quantization. For hard cases, retrain a smaller student with distillation. ONNX Runtime and ONNX Neural Compressor are the two most relevant ecosystems for this workflow. For NeuroGolf If this competition rewards compact neural policies, I would prioritize: small backbone + distillation INT8 or mixed-precision ONNX export operator fusion and graph cleanup removing unused branches and constants before export That combination usually beats trying to compress a large model after the fact. Good starting sites ONNX Runtime model optimizations ONNX quantization guide ONNX Neural Compressor I can also give you a competition-specific ONNX compression recipe for vision models, including exact export settings and a Python quantization script. Follow-ups Yes please, provide the competition-specific compression recipe Show me a Python script for INT8 quantization in ONNX Runtime I need a guide on implementing Knowledge Distillation for vision models Can you help me choose between SmoothQuant and weight-only quantization I'm struggling with accuracy loss after pruning, can you help fix it do both Absolutely — I’ll do both: a cleaner v4-style rewrite pattern and a smaller ONNX-safe reflection replacement. Clean v4 structure Your current graph logic is solid, but I’d refactor it into a named-temporary style so each node is obvious and shape-safe. That helps avoid accidental shape mismatches and makes ONNX shape inference much easier to trust. Here’s the pattern I’d use: python # Example pattern only mr_row = nd('Mul', [main_rp, 'row_1d'], [[1, 1, 10, 1]]) mr_row_sum = nd('ReduceSum', [mr_row, 'axes2'], [[1, 1, 1, 1]], keepdims=1) main_cr = nd('Div', [mr_row_sum, main_total], [[1, 1, 1, 1]]) Apply that to: centroid math, mirror math, masked min/max blocks, reflection indexing. That change does not alter behavior, but it will make the graph much safer to debug. Safer reflection replacement The riskiest part of your current model is GatherElements for reflected masks. You can replace most of that with a simpler arithmetic approach if you precompute a reflected coordinate grid and use Where. Idea Instead of: building index tensors, gathering elements, then masking again, do this: Build a reflection coordinate vector. Compare positions directly. Use Where to select reflected values. For a row reflection, the core pattern is: python ref_row = nd('Sub', ['h_mx2', 'row_grid'], [[1, 1, 10, 1]]) ref_row = nd('Abs', [ref_row], [[1, 1, 10, 1]]) # or floor/clip depending on symmetry But for your specific task, the better approach is to avoid explicit coordinate reflection entirely and instead construct the reflected mask with a position test: python row_eq = nd('Equal', ['row_grid', 'broadcast_ref_row'], [([1, 1, 10, 1], TensorProto.BOOL)]) reflected = nd('Where', [row_eq_b, main_mask, zero_mask], [[1, 1, 10, 10]]) That is only worthwhile if the reflected structure is regular enough. If the reflection is irregular, keep the gather logic but make it more explicit and split into substeps. Recommended ONNX-safe refactor I’d rewrite your reflection section like this: Horizontal branch compute h_mirror compute h_target_row cast/clamp target row build a row equality mask expand it to [1,1,10,10] select with Where Vertical branch compute v_mirror compute v_target_col clamp target col build a column equality mask expand it to [1,1,10,10] select with Where This will usually be smaller and easier to validate than GatherElements. Practical rewrite plan I would change your graph in this order: Split all nested nd(...) calls into separate assignments. Replace GatherElements with Where if the reflection is grid-regular. Keep GatherElements only if the structure is truly index-based. Run shape inference after each major section, not only at the end. Remove any unnecessary value_info entries once the graph is stable. What I would keep These parts are already good and should stay: 1D centroid computation from projections. 1D edge detection with masked min/max. Late-stage 2D materialization only when unavoidable. Padding only at the very end. What I would change first The highest-value fix is this: replace the nested inline expressions with named temporaries, then rewrite the reflection logic into a Where-based branch if possible. That gives you the biggest improvement in readability and often a smaller graph too. I can next give you a fully rewritten v4 code block in the same style as your current script, with: all nested expressions expanded, the reflection branch converted away from GatherElements where possible, and the graph layout made ONNX-shape-inference friendly. how does th4t relate to the more adcvanced techniques you gave and what i asked for onnx models # ============================================================ # NeuroGolf 2026 Kaggle Notebook Template # Small model -> train -> export ONNX -> simplify -> quantize # ============================================================ !pip -q install onnx onnxruntime onnxsim onnxruntime-tools import os import json import math import glob import random import numpy as np import pandas as pd from pathlib import Path import torch import torch.nn as nn import torch.nn.functional as F from torch.utils.data import Dataset, DataLoader import onnx from onnxsim import simplify from onnxruntime.quantization import ( quantize_static, quantize_dynamic, QuantFormat, QuantType, CalibrationDataReader, ) # ---------------------------- # Config # ---------------------------- SEED = 42 DEVICE = "cuda" if torch.cuda.is_available() else "cpu" ROOT = Path("/kaggle/input/neurogolf-2026") # adjust if needed WORK = Path("/kaggle/working/neurogolf_out") WORK.mkdir(parents=True, exist_ok=True) RAW_ONNX = WORK / "model_raw.onnx" SIM_ONNX = WORK / "model_simplified.onnx" INT8_ONNX = WORK / "model_int8.onnx" DYN_ONNX = WORK / "model_dynamic.onnx" IMG_H, IMG_W = 64, 64 BATCH_SIZE = 32 NUM_WORKERS = 2 def seed_everything(seed=SEED): random.seed(seed) np.random.seed(seed) torch.manual_seed(seed) torch.cuda.manual_seed_all(seed) seed_everything() # ---------------------------- # Data utilities # ---------------------------- def list_competition_files(): files = sorted([str(p) for p in ROOT.rglob("*")]) return files class NeuroGolfDataset(Dataset): def __init__(self, mode="train"): self.mode = mode self.samples = self._build_index() def _build_index(self): # Replace this with real competition parsing. # Example: read JSON task files from root. items = [] for p in ROOT.rglob("*.json"): items.append(str(p)) return items def __len__(self): return max(1, len(self.samples)) def __getitem__(self, idx): # Replace with real loading + preprocessing. x = torch.randn(3, IMG_H, IMG_W) y = torch.randn(3, IMG_H, IMG_W) return x, y train_ds = NeuroGolfDataset("train") val_ds = NeuroGolfDataset("val") train_loader = DataLoader( train_ds, batch_size=BATCH_SIZE, shuffle=True, num_workers=NUM_WORKERS, pin_memory=True, ) val_loader = DataLoader( val_ds, batch_size=BATCH_SIZE, shuffle=False, num_workers=NUM_WORKERS, pin_memory=True, ) # ---------------------------- # Small student model # ---------------------------- class TinyBlock(nn.Module): def __init__(self, c): super().__init__() self.conv1 = nn.Conv2d(c, c, 3, padding=1) self.conv2 = nn.Conv2d(c, c, 3, padding=1) self.act = nn.GELU() def forward(self, x): r = x x = self.act(self.conv1(x)) x = self.conv2(x) return self.act(x + r) class StudentModel(nn.Module): def __init__(self, in_ch=3, base=32, out_ch=3, blocks=3): super().__init__() self.stem = nn.Conv2d(in_ch, base, 3, padding=1) self.blocks = nn.Sequential(*[TinyBlock(base) for _ in range(blocks)]) self.head = nn.Conv2d(base, out_ch, 1) def forward(self, x): x = F.gelu(self.stem(x)) x = self.blocks(x) return self.head(x) model = StudentModel(base=24, blocks=2).to(DEVICE) # Optional: load checkpoint # ckpt = torch.load("/kaggle/input/.../student.pth", map_location=DEVICE) # model.load_state_dict(ckpt) # ---------------------------- # Teacher for distillation # ---------------------------- class TeacherModel(nn.Module): def __init__(self): super().__init__() self.net = StudentModel(base=64, blocks=6) def forward(self, x): return self.net(x) teacher = TeacherModel().to(DEVICE) teacher.eval() for p in teacher.parameters(): p.requires_grad = False # Optional: load teacher # teacher.load_state_dict(torch.load("/kaggle/input/.../teacher.pth", map_location=DEVICE)) # ---------------------------- # Losses # ---------------------------- def distill_loss(student_out, teacher_out, target, alpha=0.7): return alpha * F.mse_loss(student_out, teacher_out) + (1 -

The Kaggle competition itself is about building the smallest neural networks for ARC-AGI-style transformations, so the workflow should favor a small student model, then ONNX simplification and quantization, rather than trying to shrink a large model after the fact. How they map Small student model = architecture slimming. This is your biggest size win, because a smaller model is always easier to compress than a big one. Teacher/student distillation = accuracy recovery after shrinking. It helps the small model behave like a larger one. ONNX export = the packaging step. This makes the model portable and ready for runtime optimization. ONNX simplification = graph cleanup. ONNX Simplifier removes redundant ops and folds constants, which reduces graph clutter and often file size. Static INT8 quantization = the main compression step. This is where file size and memory usage usually drop the most for convolutional or feedforward models. Dynamic quantization fallback = safer but sometimes weaker compression. It is useful when static calibration hurts accuracy too much. What your current notebook is missing Your template already includes the basic pipeline, but it is still a generic baseline, not yet a competition-optimized ONNX solution. The missing part is the actual model design and export strategy that minimizes graph size before quantization. In other words, the notebook shows where compression happens, but not yet the best shape of the model to compress. How it connects to your Task 062 graph Your Task 062 ONNX builder is already a form of advanced optimization, because it avoids expensive full-grid intermediates and replaces them with projection-based logic. That is exactly the kind of structural reduction that goes beyond normal quantization: you are shrinking the computation graph itself, not just the stored weights. The best way to think about it is: the notebook template = training and export framework, Task 062 builder = hand-optimized symbolic model, advanced ONNX techniques = post-export compression and cleanup. What to do next For this competition, I would combine both approaches: Keep your symbolic Task 062-style logic if it already solves the task well. Refactor it to reduce intermediate tensors and risky ops. Export the smallest clean ONNX graph possible. Run simplification. Quantize only the layers that survive calibration without accuracy loss. So the key point is: the notebook template is useful, but your current ONNX builder is actually closer to the advanced answer because it directly reduces graph complexity. The strongest solution is to merge them: use the notebook for training/distillation and use the Task 062-style graph minimization for export and inference. Would you like me to turn your Task 062 ONNX builder into a clean v4 version that is aligned with quantization and simplification from the notebook pipeline? Follow-ups Yes, rewrite my Task 062 builder to be v4-style and quantization ready Yes, show me how to apply static INT8 quantization to my current v3 model Yes, please integrate the ONNX simplifier directly into my v3 template code Yes, let's build the model architecture specifically for optimal compression Yes, show me the code for the v4 structure first and then the export steps Yes, rewrite my Task 062 builder to be v4-style and quantization ready Yes — and the main adjustment is this: your Task 062 builder should be written like a quantization-friendly float32 graph, not like a hand-tuned one-off export script. That means: fewer nested expressions, static shapes, cleaner operator choices, and a layout that simplifies well before QDQ INT8 quantization. ONNX Runtime recommends running model preprocessing and graph optimization before quantization, and prefers tensor-oriented QDQ quantization with calibration data for best results. What “quantization ready” means A quantization-ready ONNX graph should: use static shapes where possible, avoid unnecessary dynamic control flow, keep arithmetic branches explicit, minimize exotic ops, and simplify cleanly before calibration. Your current builder is already good at graph shrinking, but it still needs refactoring so the float model is easier for ONNX simplification and QDQ calibration to process. That is why the v4-style rewrite matters: it does not just make the code cleaner, it makes the exported model more stable for quantization. What to change in your builder Split nested nd(...) calls into named temporaries. This helps shape inference and makes quantization debug easier. Keep the model fully static. You already have fixed [1, 10, 30, 30] input/output shapes, which is good. Prefer Where, Add, Mul, ReduceSum, Cast, Clip, Reshape. These are easier to quantize than overly clever index-heavy constructions. Avoid GatherElements if you can. It is often the least quantization-friendly part of graph-style models. Export float32 first, simplify second, quantize third. That order is the most robust path. How it connects to your advanced ONNX goal Your advanced goal was not just “make an ONNX model,” but “make the ONNX model smaller, cleaner, and still accurate.” The Task 062 style is already a form of structural compression because it reduces intermediate tensors before quantization even starts. The remaining improvement is to make the graph friendlier to ONNX simplification and QDQ static quantization, which is where the v4 rewrite helps most. Practical export order Use this order: Build the v4-style float graph. Run ONNX shape inference. Run onnxsim simplification. Run static quantization with calibration data. Benchmark INT8 vs float32. Keep a fallback dynamic quantized model if static accuracy drops. Bottom line So the relationship is: your Task 062 logic = advanced structural reduction, the v4 rewrite = cleaner float graph, simplification = remove redundant nodes, static QDQ quantization = final size and speed reduction. That is the correct end-to-end path for the ONNX model you were asking for. I can now rewrite your Task 062 builder into a full v4 code block with: named temporaries, quantization-friendly ops, and a safer reflection branch. rewrite your Task 062 builder into a full v4 code block with: named temporaries, quantization-friendly ops, and a safer reflection branch. Completed 2 steps Your Task 062 builder is the part that changes the model before export, while the advanced techniques I gave you are the parts that shrink or stabilize the model after export. In ONNX terms, your rewritten v4 graph should already be smaller and cleaner, and then simplification plus quantization finish the job. How they connect Named temporaries help shape inference and make the graph easier to simplify and debug. ONNX Runtime’s quantization workflow recommends preprocessing such as shape inference and model optimization before quantization. Quantization-friendly ops matter because ONNX Runtime quantization works best on models with known tensor shapes and a clean graph, and static quantization uses calibration data to set activation ranges. A safer reflection branch is a structural improvement, not just an optimization. If you replace fragile GatherElements logic with simpler Where/mask logic, you reduce graph complexity before quantization even starts. What your v4 rewrite should do Split nested expressions into named steps. Keep shapes static if possible. Prefer simple ops like Add, Mul, Where, ReduceSum, Cast, Clip, and Reshape. Avoid expensive or awkward indexing ops unless they are truly necessary. Export float32 first, simplify second, quantize third. Why this helps the competition For a smallest-network competition, the biggest win is usually architecture slimming first, then ONNX simplification, then static INT8 quantization. ONNX Runtime explicitly says quantization is a post-training transform, and static quantization is the usual choice for CNN-style models, while dynamic quantization is more often used for transformer/RNN-style models. If your builder already removes unnecessary intermediate tensors, the quantizer has less work to do and accuracy is often easier to preserve. Best export order Rewrite the graph in v4 style. Run ONNX shape inference or preprocessing. Run onnxsim. Apply static QDQ quantization with calibration data. Benchmark against float32. Keep dynamic quantization only as a fallback. Practical takeaway So the relationship is simple: the advanced techniques are the compression layer, and your Task 062 builder is the structural layer underneath it. The v4 rewrite is not separate from the advanced ONNX approach — it is what makes the advanced approach work better. I can now rewrite your Task 062 builder into a full v4 ONNX-safe code block with named temporaries, quantization-friendly ops, and the safer reflection branch. rewrite your Task 062 builder into a full v4 code block with: named temporaries, quantization-friendly ops, and a safer reflection branch. Yes — here is a full v4-style rewrite pattern for your Task 062 builder that is more ONNX-simplification- and quantization-friendly. It follows the same logic as your current graph, but breaks nested expressions into named temporaries, prefers simpler ops, and replaces brittle reflection indexing with a mask/Where approach where possible. v4 builder pattern python import onnx from onnx import helper, TensorProto, numpy_helper def nd(op, inputs, outputs, attrs=None, domain=""): attrs = attrs or {} return helper.make_node(op, inputs=inputs, outputs=outputs, domain=domain, **attrs) def vi(name, shape, dtype=TensorProto.FLOAT): return helper.make_tensor_value_info(name, dtype, shape) def cst(name, arr, dtype=None): arr = np.asarray(arr) if dtype is None: if arr.dtype == np.float32 or arr.dtype == np.float64: dtype = TensorProto.FLOAT elif arr.dtype == np.int64: dtype = TensorProto.INT64 elif arr.dtype == np.int32: dtype = TensorProto.INT32 elif arr.dtype == np.bool_: dtype = TensorProto.BOOL else: dtype = TensorProto.FLOAT return numpy_helper.from_array(arr, name=name) def build_task062_v4(): nodes = [] inits = [] vis = [] #

It prefers ReduceSum, Add, Mul, Div, Relu, Cast, Clip, and Where-like masking patterns, which are generally easier to simplify and quantize than deeply nested index-heavy logic. The reflection logic is rewritten as a bounded index test plus equality mask, which is usually safer than GatherElements for export and calibration stability. The order matches ONNX Runtime’s recommended flow: optimize/simplify first, then static quantization with calibration data. What to do next Replace the random initializers with your trained weights. Run onnxsim on task062_v4.onnx. Use static QDQ quantization with a calibration reader. Compare float vs INT8 output before submitting. Important note Your original Task 062 logic may have task-specific indexing or reflection rules that I cannot see here, so this is a safe structural rewrite pattern, not a guaranteed drop-in semantic clone. If you paste the actual builder code, I can rewrite it line-for-line into a v4 version with the exact same behavior and the same ONNX-friendly structure. combne wth import torch import onnx from onnxsim import simplify from onnxruntime.quantization import quantize_static, QuantFormat, QuantType, CalibrationDataReader model.eval() dummy = torch.randn(1, 3, H, W) torch.onnx.export( model, dummy, "student.onnx", opset_version=17, input_names=["input"], output_names=["output"], dynamic_axes=None, do_constant_folding=True ) onnx_model = onnx.load("student.onnx") model_simp, check = simplify(onnx_model) assert check onnx.save(model_simp, "student_simplified.onnx") class MyCalibrationDataReader(CalibrationDataReader): def __init__(self, data_list): self.data_list = iter(data_list) def get_next(self): try: x = next(self.data_list) return {"input": x.numpy()} except StopIteration: return None calib_reader = MyCalibrationDataReader(calibration_batches) quantize_static( "student_simplified.onnx", "student_int8.onnx", calib_reader, quant_format=QuantFormat.QDQ, activation_type=QuantType.QInt8, weight_type=QuantType.QInt8 ) Here’s the cleaned, combined version of your export → simplify → static INT8 quantization flow, with the missing imports and a slightly safer calibration reader. This matches the standard ONNX Runtime workflow: export a float model first, simplify it, then apply static quantization with calibration data. python import torch import onnx from onnxsim import simplify from onnxruntime.quantization import ( quantize_static, QuantFormat, QuantType, CalibrationDataReader, ) model.eval() dummy = torch.randn(1, 3, H, W) torch.onnx.export( model, dummy, "student.onnx", opset_version=17, input_names=["input"], output_names=["output"], dynamic_axes=None, do_constant_folding=True, ) onnx_model = onnx.load("student.onnx") model_simp, check = simplify(onnx_model) assert check, "Simplified ONNX model could not be validated" onnx.save(model_simp, "student_simplified.onnx") class MyCalibrationDataReader(CalibrationDataReader): def __init__(self, data_list): super().__init__() self.data_list = iter(data_list) def get_next(self): try: x = next(self.data_list) return {"input": x.cpu().numpy()} except StopIteration: return None calib_reader = MyCalibrationDataReader(calibration_batches) quantize_static( "student_simplified.onnx", "student_int8.onnx", calib_reader, quant_format=QuantFormat.QDQ, activation_type=QuantType.QInt8, weight_type=QuantType.QInt8, ) Small fixes I added super().__init__() in the calibration reader, which is the safer pattern for ONNX Runtime quantization readers. I changed x.numpy() to x.cpu().numpy() so it works even if the calibration tensors are on GPU. dynamic_axes=None is correct here if you want a fully static export, which is usually friendlier for simplification and static calibration. Practical order Export student.onnx. Simplify into student_simplified.onnx. Quantize into student_int8.onnx. Test accuracy and fallback to dynamic quantization only if INT8 loses too much quality. One important caution Your calibration_batches must yield tensors in exactly the same shape and preprocessing as the model input expects, because static quantization calibrates activation ranges from those samples. cpombne code 062 wth your recommended dvnce code import torch import onnx from onnxsim import simplify from onnxruntime.quantization import ( quantize_static, QuantFormat, QuantType, CalibrationDataReader, ) model.eval() dummy = torch.randn(1, 3, H, W) torch.onnx.export( model, dummy, "student.onnx", opset_version=17, input_names=["input"], output_names=["output"], dynamic_axes=None, do_constant_folding=True, ) onnx_model = onnx.load("student.onnx") model_simp, check = simplify(onnx_model) assert check, "Simplified ONNX model could not be validated" onnx.save(model_simp, "student_simplified.onnx") class MyCalibrationDataReader(CalibrationDataReader): def __init__(self, data_list): super().__init__() self.data_list = iter(data_list) def get_next(self): try: x = next(self.data_list) return {"input": x.cpu().numpy()} except StopIteration: return None calib_reader = MyCalibrationDataReader(calibration_batches) quantize_static( "student_simplified.onnx", "student_int8.onnx", calib_reader, quant_format=QuantFormat.QDQ, activation_type=QuantType.QInt8, weight_type=QuantType.QInt8, ) Yes — for Kaggle validity, the 062 output model must preserve the exact existing format, so the safest combined code is: build the 062-style ONNX graph, save it, simplify it, then quantize it, without changing the input/output contract.

One important warning The code above is Kaggle-safe only if the existing 062 competition model truly has that same I/O format.

It keeps the final output shape as [1, 10, 30, 30], which is what your Kaggle-valid format needs. It preserves the export → simplify → quantize flow from ONNX Runtime. One correction Your original 062 code uses opset 18, so I kept that here. If the competition environment is sensitive to opset versions, keep it at 18 unless you know 17 is required. Important note This version still uses GatherElements in the reflection branch because that is the closest faithful match to your original 062 behavior. If you want, I can produce a second version that replaces only the reflection part with a safer mask-based branch while preserving the same output format. yes Yes — here’s the safer version: keep the same Task 062 input/output contract, but replace the GatherElements reflection branch with mask-based Where logic so the graph is easier to simplify and usually more quantization-friendly. python
