Mosaic MLP Composer

Mosaic Composer is an open-source framework that simplifies building and training MLPs (multi-layer perceptrons) with PyTorch. It abstracts training loop boilerplate, hyperparameter management, and distributed training complexity. You define the model, data, and loss; Composer handles the rest. Mosaic Composer is especially powerful for rapid experimentation: tweak architecture, retrain, compare results. Ideal for researchers, prototyping, and small-to-medium teams.
