Deep Bayesian active learning using in-memory computing hardware
Abstract Labeling data is a time-consuming, labor-intensive and costly procedure for many artificial intelligence tasks. Deep Bayesian active learning (DBAL) boosts labeling efficiency exponentially, substantially reducing costs. However, DBAL demands high-bandwidth data transfer and probabilistic computing, posing great challenges for conventional deterministic hardware. Here we propose a memristor stochastic gradient Langevin dynamics in situ learning…

India’s science workforce is under-used, survey finds
There are gaps in the best use of skilled labour across multiple scientific disciplines. Credit: Subhra Priyadarshini India’s science and technology (S&T) workforce is underutilized, a recent survey reveals. It exposes substantial gaps in the best use of skilled labour across multiple scientific disciplines and domains. This underutilization stems from a mismatch between skill supply…
