Reinforcement Learning with NVIDIA NeMo-RL: Megatron-Core Support for Optimized Training Throughput

Understanding Reinforcement Learning with NVIDIA NeMo-RL

Reinforcement Learning (RL) has rapidly evolved, offering innovative solutions in various fields such as robotics, gaming, and autonomous systems. At the forefront of this technological evolution is NVIDIA’s NeMo-RL, integrating advanced machine learning capabilities to enhance training efficiency and outcomes. Notably, the introduction of Megatron-Core support marks a significant step towards optimizing training throughput, enabling developers to harness the power of large-scale deep learning efficiently.

What is Reinforcement Learning?

Reinforcement Learning is a paradigm of machine learning where agents learn to make decisions by interacting with an environment. Unlike traditional supervised learning, in which models are trained on labeled data, RL relies on the concept of rewards and penalties. The goal is to learn a policy that maximizes cumulative rewards over time. RL has numerous applications, from game-playing AI to self-driving cars.
