Feature engineering — the process of using domain knowledge to extract features from raw data — is essential to tuning machine learning performance. It’s also typically arduous and involves rewriting features before they’re deployed, which is why in 2018 Ben Chambers and Davor Bonaci cofounded Kaskada, which uses mining techniques to compute and serve AI features in real time. Today the…

Speech recognition is an acute area of interest for Apple, whose cross-platform Siri virtual assistant is used by over 500 million customers worldwide. This past week, the tech giant published a series of preprint research papers investigating techniques to improve voice trigger detection and speaker verification, as well as language identification for multiple speakers. Speaker verification and…

Sequence-to-sequence AI models, which were introduced by Google in 2014, aim to map fixed-length input (usually text) with a fixed-length output where the length of the input and output might differ. They’re used in text-generating tasks including summarization, grammatical error correction, and sentence fusion, and recent architectural breakthroughs have made them more capable than before. But…
