Project mention: Generative AI Interview for Senior Data Scientists: 50 Key Questions and Answers | dev.to | 2025-05-06
How it works: A model trained in one framework can be converted to the ONNX format. This format can then be run on various hardware or inference engines that support it (e.g., ONNX Runtime). It facilitates easy model transfer and execution even if the development framework and deployment environment differ.

DALI
A GPU-accelerated library containing highly optimized building blocks and an execution engine for data processing to accelerate deep learning training and inference applications.
How to Accomplish: Use a combination of geometric transformations (e.g., rotation, scaling, cropping, flipping), color space adjustments (e.g., brightness, contrast, saturation), and other techniques (e.g., noise injection, blurring, cutout). Libraries such as ImgAug, DeepMind Augmentation, Albumentations, and NVIDIA DALI offer a wide range of ready-to-use augmentation techniques that can introduce the necessary diversity into your dataset.

TNN
TNN: developed by Tencent Youtu Lab and Guangying Lab, a uniform deep learning inference framework for mobile、desktop and server. TNN is distinguished by several outstanding features, including its cross-platform capability, high performance, model compression and code pruning. Based on ncnn and Rapidnet, TNN further strengthens the support and performance optimization for mobile devices, and also draws on the advantages of good extensibility and high performance from existed open source efforts
