The New ONNX Model Zoo 01_Groq-ONNX Meetup presentation - Ramakrishnan Sivakumar.pdf ONNX (Open Neural Network Exchange) Model Zoo has been an invaluable resource for AI and machine learning practitioners. However, we believe there is immense untapped potential that remains to be explored. Recognizing the need to cater to an evolving technological landscape and the diverse needs of users, we embarked on a mission to revamp the ONNX Model Zoo. Our objective has been twofold: Firstly, to augment the user experience by introducing a more intuitive, user-friendly interface, and efficient navigation features, making it easier for users to find the models that meet their requirements. Secondly, we strive to broaden the spectrum of models offered in the repository. We are expanding the selection of models to include cutting-edge architectures from various domains such as Computer Vision, Natural Language Processing, Audio, Reinforcement Learning, MultiModal, Generative AI and Graph Machine Learning. | Ramakrishnan Sivakumar, Groq Ramakrishnan Sivakumar is a Machine Learning (ML) Software Engineer at Groq.

Analysis of Failures and Risks in Deep Learning Model Converters: A Case Study in the ONNX Ecosystem 02_pu-ONNX Day Presentation - Jajal-Davis.pdf Software engineers develop, fine-tune, and deploy deep learning (DL) models. They use and re-use models in a variety of development frameworks and deploy them on a range of runtime environments. In this diverse ecosystem, engineers use DL model converters to move models from frameworks to runtime environments. However, errors in converters can compromise model quality and disrupt deployment. The failure frequency and failure modes of DL model converters are unknown. In this talk, we present a failure analysis on DL model converters. We characterized failures in model converters associated with ONNX (Open Neural Network eXchange). We analyzed past failures in the ONNX converters in two major DL frameworks, PyTorch and TensorFlow. The symptoms, causes, and locations of failures (for N=200 issues), and trends over time are also reported. We also evaluated present-day failures by converting 8,797 models, both real-world and synthetically generated instances. The consistent result from both parts of the study is that DL model converters commonly fail by producing models that exhibit incorrect behavior: 33% of past failures and 8% of converted models fell into this category. Our results motivate work to make DL software simpler to maintain, extend, and validate. | James C. Davis, Purdue James C. Davis is a professor of electrical & computer engineering at Purdue University. His research is in software engineering, studying the engineering of software-intensive computing systems.

Extensions to ONNX for Multi-Device Support The AI industry has grown model size at a faster rate than the growth in hardware capabilities. This model growth has made it difficult to run SOTA models utilizing ONNX due to no support for expressing execution of the network on multiple devices. This proposal introduces a few extensions to ONNX that allow expression of multi-device capability with minor changes relative to a single device network. By expressing some optional information to an ONNX network, the model can be scaled to multiple devices. | Micah Villmow, NVIDIA Micah Villmow is a principal engineer at NVIDIA.

INT8 Quantization for Large Language Models with Intel Neural Compressor (pre-recorded) The explosive growth of large language models (LLMs) has facilitated a significant number of breakthroughs in fields like text analysis, language translation, and chatbot technologies. However, the deployment of LLMs presents a formidable challenge due to their large parameter (e.g., over 700GB memory required to run BLOOM-176B model in FP32), making them impractical to run on commodity hardware. Users, therefore, have an ongoing demand for methods of compressing LLMs that maintain comparable accuracy while reducing their memory footprint, for which general quantization recipes may not work. To compress LLMs with reasonable accuracy, Intel® Neural Compressor integrates as well as enhances SmoothQuant algorithm, which effectively addresses the compression challenge by efficiently compensating for the accuracy loss introduced by activation quantization. Our team has validated the efficacy of this solution on numerous LLMs such as GPT-J, LLaMA, and BLOOM, achieving promising latency on Intel hardware. Furthermore, Intel® Neural Compressor eliminates the gap that exists in exporting int8 PyTorch models to ONNX format, making it ideal for production deployment. We continue to upload ONNX models to the ONNX model zoo and Hugging Face hub (e.g., GPT-J and Whisper-large), which can make contributions to the ONNX community. | Mengni Wang, Intel Mengni is a Software Engineer at Intel focusing on Intel(R) Neural Compressor development and model quantization.

Dynamic Dimension Analysis in onnx-mlir Compiler (pre-recorded) onnx-mlir-dynamic-dimension-analysis.pdf ONNX models often have dynamic dimensions such as batch size or sequence length, which makes a compiler difficult to generate optimal code or to decide whether an operator is suitable for running on AI accelerators or not. While ONNX provides shape inference to infer the relationship among dynamic dimensions, it is limited to ONNX operators. Meanwhile, MLIR-based compilers often have many intermediate representation levels including operators rather than ONNX operators. In this talk, we introduce a dynamic dimension analysis in onnx-mlir compiler, which utilizes operator's ShapeHelper to analyze the relationship between dynamic dimensions such as whether two dynamic dimensions are equal or not. Every operator in onnx-mlir has a ShapeHelper interface, which makes the analysis applicable to a broad range of models. We also show how the analysis helps the compiler optimize CPU operators or offload them to AI accelerators. | Tung D. Le, IBM Tung D. Le is a Staff Research Scientist at IBM Research - Tokyo.

HE-MAN – Homomorphically Encrypted MAchine learning with oNnx models (pre-recorded), In this talk, I will present our latest publication: HE-MAN – Homomorphically Encrypted MAchine learning with oNnx models. Machine learning (ML) algorithms play a crucial role in the success of products and services, especially with the abundance of data available. Fully homomorphic encryption (FHE) is a promising technique that enables individuals to use ML services without sacrificing privacy. However, integrating FHE into ML applications remains challenging. Existing implementations lack easy integration with ML frameworks and often support only specific models. To address these challenges, we present HE-MAN, an open-source two-party machine learning toolset. HE-MAN facilitates privacy-preserving inference with ONNX models and homomorphically encrypted data. With HE-MAN, both the model and input data remain undisclosed. Notably, HE-MAN offers seamless support for a wide range of ML models in the ONNX format out of the box. We evaluate the performance of HE-MAN on various network architectures and provide accuracy and latency metrics for homomorphically encrypted inference. | Martin Nocker, MCI 2013-2016 Bachelor's degree in Computer Science from University of Innsbruck, Austria, 2016-2018 Master's degree in Electrical and Computer Engineering from Technical University of Munich (TUM), Germany. 2019-2020 Software Engineer at Swarovski, Wattens, Austria 2021-now Research Assistant at MCI (Management Center Innsbruck), Austria 2021-now PhD Student at University of Rostock, Germany |
