NeMo's technical principles

  • Modular architectureNeMo employs a modular design, allowing developers to select, combine, and reuse pre-built modules, such as data loaders, model components, loss functions, and optimizers, to build customized AI models.
  • Deep learning frameworkNeMo is built on PyTorch and leverages powerful deep learning capabilities, supporting dynamic computation graphs and automatic gradient calculation.
  • Neural modulesIn NeMo, a "neural module" is the basic unit for building complex models. It can be any part of a neural network, such as a layer, loss function, or evaluation metric.
  • Neural typeNeMo introduces the concept of "neural type" to define the data type and format passed between neural modules, ensuring that data flows correctly between modules.
  • Parallel and distributed trainingNeMo supports data parallelism, model parallelism, and pipeline parallelism, enabling models to be trained on multiple GPUs and nodes, improving training efficiency and scalability.
  • pre-trained modelNeMo provides a variety of pre-trained models that have been trained on large amounts of data and can serve as a starting point for new tasks, which can be fine-tuned to adapt to specific applications.
