openvino

openvinotoolkit/openvino · ★ 11K

OpenVINO is Intel's open-source toolkit for optimizing and deploying AI inference — it takes trained deep learning models for vision, speech, NLP, and generative AI and runs them faster, from edge devices to cloud servers.

autumn-recruitment

Akun-python/autumn-recruitment · ★ 263

It is a community-built, Chinese-language collection of Jupyter notebooks covering math foundations, data structures, machine learning, deep learning, LLMs, agents, AI infrastructure, speech, and data science, aimed at job-hunting ('autumn recruitment') interview prep in the LLM era.
