Model optimization and performance contributions

Contributions to OpenVINO PyTorch Frontend: added missing operators (smooth_l1_loss, fake quant ops, quantile, linalg_multi_dot), debugging system design, INT8/FP16 benchmarking (e.g., EfficientNet-V2-XL), and integration across Model Optimizer and Runtime. Includes operator validation, code-path debugging, and cross-framework consistency improvements.

Responsibilities:
Executed systematic experiments to evaluate model performance using Batch Size, nstreams, nireq, and CPU pinning. Compared Precision Modes (FP32, FP16, INT8, Mixed Precision) with quantization and post-training optimization. Measured and visualized key metrics such as Latency, FPS, and Memory Footprint, generating histograms and comparative graphs to analyze trade-offs between accuracy and efficiency.https://github.com/TamiShaks-2
Researched Intel OpenVINO architecture (Frontend, Core, Runtime) and neural network computation flow. Gained hands-on understanding of graph representation (IR), model conversion, and optimization pipelines from PyTorch to OpenVINO.
Processed the COCO dataset, performed format conversion (COCO → YOLOv9), and created customized YAML configuration files for experiments. Executed YOLOv9-Seg and EfficientNetV2 models using OpenVINO Runtime, analyzed Latency and Throughput metrics, generated histograms and performance graphs, and optimized inference efficiency across different hardware configurations.
