NVIDIA Merlin vs. warpt-ctc

NVIDIA Merlin empowers data scientists, machine learning engineers, and researchers to build high-performing recommenders at scale. Merlin includes libraries, methods, and tools that streamline the building of recommenders by addressing common preprocessing, feature engineering, training, inference, and deploying to production challenges. Merlin components and capabilities are optimized to support the retrieval, filtering, scoring, and ordering of hundreds of terabytes of data, all accessible through easy-to-use APIs.

warpt-ctc is a loss function useful for performing supervised learning on sequence data, without needing an alignment between input data and labels that can be used to train end-to-end systems for speech recognition
