An In-Cell Weight Update Scheme Using One-Hot Gradients for On-Chip Learning

Mathieu Chêne, Benoit Larras, Andreas Kaiser, Antoine Frappé

In the context of edge AI, the embedded models need to be retrained on-chip. The more the backward path and the calculation the gradient (two important steps during learning) are optimized by literature, the more it becomes interesting to optimize weight update operation. This work proposes to…

Two-dimensional materials (2DMs) offer unique properties primarily due to their crystallographic structure, which consists of weakly coupled layers composed of one to few atomic planes where the atoms are covalently bonded. This specific structure results in the absence of dangling bonds at the…, Les matériaux bidimensionnels (2MDs) offrent des propriétés uniques principalement dues à leur structure cristallographique, composée de couches faiblement couplées constituées d'un à quelques plans atomiques où les atomes sont liés de manière covalente.
