Amazon AI Releases PyTorch-Based ‘Sockeye 3’: The Latest Version of the Sockeye Toolkit for Neural Machine Translation (NMT)

The performance of machine translation systems, which previously relied on phrase-based systems, has suddenly improved with the advent of neural network-based models. An open-source framework called Sockeye was released in 2018. This framework provides quick and dependable PyTorch implementation for neural machine translation (NMT) and other related tasks. It supports Amazon Translate and several other NMT applications. In 2020, Sockeye 2, its improved version, was also launched. In its most recent paper, Amazon has now made available the most recent version, Sockeye 3. This PyTorch-based Neural Machine Translation toolkit can be used to effectively train models that are more powerful and quick. The most recent version includes a more streamlined codebase that allows scientists to conduct tests more rapidly and offers them the freedom to transition new concepts from research to production quickly. Sockeye 3 outperforms rival PyTorch implementations on GPUs by up to 126 percent, while on CPUs, it outperforms them by up to 292 percent.

By fitting larger batches into memory, the toolkit accelerates a distributed mixed precision training technique to produce faster calculations and speedups. Additionally, by starting independent training processes that employ PyTorch’s distributed data parallelism to synchronize updates, it can scale to any number of GPUs and any size of training data. To reduce the effects of dynamic forms and data-dependent control flow, Sockeye 3 uses static computation graphs in its architectural design. This allows it to trace multiple model components using PyTorch’s JIT compiler. All the models that can be trained using Sockeye 2 may be converted to models running on Sockeye 3 with PyTorch, one of the tool’s most helpful features. Sockeye 3 also consists of several new features. The toolkit offers parameter freezing for fine-tuning and replacing the decoder’s self-attention layers with Simpler Simple Recurrent Units (SSRUs).

Additionally, it allows users to define freely chosen token sequences for any input on both the source and target sides. Studies revealed that when compared to industry-standard NMT models like Fairseq and OpenNMT, Sockeye performs better. In conclusion, Sockeye 3 offers NMT more sophisticated functionality and substantially faster model implementations. It has been open-sourced under an Apache 2.0 license, similar to earlier versions. The Amazon team cordially invites community members to add on to their open-source library.
