Graph Neural Stochastic Differential Equations for Learning Brownian Dynamics

no code implementations20 Jun 2023 Suresh Bishnoi, Jayadeva, Sayan Ranu, N. M. Anoop Krishnan

Here, we propose a framework, namely Brownian graph neural networks (BROGNET), combining stochastic differential equations (SDEs) and GNNs to learn Brownian dynamics directly from the trajectory.

StriderNET: A Graph Reinforcement Learning Approach to Optimize Atomic Structures on Rough Energy Landscapes

no code implementations29 Jan 2023 Vaibhav Bihani, Sahil Manchanda, Srikanth Sastry, Sayan Ranu, N. M. Anoop Krishnan

Optimization of atomic structures presents a challenging problem, due to their highly rough and non-convex energy landscape, with wide applications in the fields of drug design, materials discovery, and mechanics.

Cementron: Machine Learning the Constituent Phases in Cement Clinker from Optical Images

no code implementations6 Nov 2022 Mohd Zaki, Siddhant Sharma, Sunil Kumar Gurjar, Raju Goyal, Jayadeva, N. M. Anoop Krishnan

Specifically, we finetune the image detection and segmentation model Detectron-2 on the cement microstructure to develop a model for detecting the cement phases, namely, Cementron.

Lagrangian Neural Network with Differentiable Symmetries and Relational Inductive Bias

no code implementations7 Oct 2021 Ravinder Bhattoo, Sayan Ranu, N. M. Anoop Krishnan

However, these models still suffer from issues such as inability to generalize to arbitrary system sizes, poor interpretability, and most importantly, inability to learn translational and rotational symmetries, which lead to the conservation laws of linear and angular momentum, respectively.
