Fairseq
Fairseq is a deep learning research toolkit and sequence-to-sequence framework built on PyTorch. It provides a system for training and deploying models that map input sequences to output sequences, with a primary focus on neural machine translation and speech recognition.
The toolkit allows for the generation of text sequences through search algorithms such as beam search and nucleus sampling. It includes capabilities for producing synthetic parallel training data by translating monolingual text using reverse sequence models.
The framework supports large scale model training through multi-device parallelism and mixed-precision training. It features a registry-based system for extending model components, optimization criteria, and learning rate schedulers, as well as tools to evaluate translation quality using standardized scoring metrics.
