About me

Keigo NISHIDA (西田 圭吾)

I am a postdoctoral researcher in the Laboratory for Computational Molecular Design at RIKEN BDR, and I also concurrently work in the Approximate Bayesian Inference Team at RIKEN AIP. In RIKEN, I am working on exploring new computers that efficiently process Bayesian neural netrworks and applying Bayesian deep learning to drug discovery. I am also a visiting researcher at the CiNet working on fluctuation-driven information processing.

Reserch Keywords : Bayesian Deep Learning, Variational Inference, Uncertainty, Domain Specific Architectures
