Project mention: None of the top 10 projects in GitHub is actually a software project 🤯 | dev.to | 2025-05-10
We see an addition to the AI community with AutoGPT. Along with Tensorflow they represent the AI community in the software category, which is getting relevant (2 out of 8). We can expect in the future to have new AI projects in the top 25 such as Transformers or Ollama (currently top 34 and 36, respectively).

PaddlePaddle
PArallel Distributed Deep LEarning: Machine Learning Framework from Industrial Practice （『飞桨』核心框架，深度学习&机器学习高性能单机、分布式训练和跨平台部署）
PaddlePaddle (so good they named it twice) predates Ray and supports both data parallel and model-parallel training. It is still being developed.
https://github.com/PaddlePaddle/Paddle
They have pedigry.

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.

MocapNET
We present MocapNET, a real-time method that estimates the 3D human pose directly in the popular Bio Vision Hierarchy (BVH) format, given estimations of the 2D body joints originating from monocular color images. Our contributions include: (a) A novel and compact 2D pose NSRM representation. (b) A human body orientation classifier and an ensemble of orientation-tuned neural networks that regress the 3D human pose by also allowing for the decomposition of the body to an upper and lower kinematic
