Anoop Cherian I am a Senior Principal Research Scientist at Mitsubishi Electric Research Labs (MERL), Cambridge, MA and an Adjunct Senior Lecturer with the Australian National University, Canberra. From 2014-2017, I was a Research Fellow at the Australian National University, working with Prof. Stephen Gould and Prof. Richard Hartley. Before that (2012-2014), I was a postdoctoral researcher at Inria (Grenoble) with Dr. Cordelia Schmid and Dr. Julien Mairal. I also collaborate with Prof. Suvrit Sra and Prof. Josh Tenenbaum at MIT. I did my PhD (2013) at the University of Minnesota, Minneapolis, USA under Prof. Nikolaos Papanikolopoulos.  Prior to that I was a software design engineer at Microsoft. I received my undergraduate (honors) degree in computer science and engineering at the National Institute of Technology (NIT), Calicut, India in 2002. I have broad interests in machine learning, including computer vision, language modeling, and robotics. A few big problems of current research interests are: · Large Language Models and Cognition · Multimodal Embodied Intelligence · Neuro-Symbolic Reasoning and Scene Graphs · Generative/Diffusion Models for Image/Video Synthesis · Contrastive/Self-supervised Learning · Non-convex/Riemannian Optimization on Matrix Manifolds My approaches usually use deep learning, geometric optimization, graph neural networks, and generative methods.
