Chemistry-informed Transformers for Reaction Prediction and Retrosynthesis

Date: 10 May 2023

The transformer architecture has remarkably improved the accuracy of sequence modeling tasks (eg. language translation) but could they be used to model chemical reactions? Do chemical reactions have some similarity with natural language that allows for the use of powerful transformer-inspired architectures? How would the molecules be represented in such...

The Network of Organic Chemistry: network statistics, chemistry insights, and AI applications

Date: 20 April 2023

Imagine we create a huge, single network of organic chemistry reactions where each unique molecule is represented as a node and molecules that take part in a reaction are connected with directed edges. Such a network would be representative of the current reaction chemistry knowledge. Obviously, some nodes would be...

grammar2vec: Molecular property prediction using SMILES grammar

Date: 11 April 2023

Ever wondered how to inject chemistry knowledge into machine learning models to accurately predict properties of molecules? How would a molecule be represented before it is input to an ML model? How could the representation be made more chemistry-aware and ensure it is complete and accurate? Do natural language processing...

Can AI take over chemistry (and chemists)?

Date: 12 March 2021

We have all been hearing the following auguries quite frequently in recent years -- "Machines are going to replace humans in all the tasks that you could imagine?", "Artificial Intelligence is going to solve all the problems (but invent several others) that the human civilization currently suffers from!" and my...

Reflecting on My Learnings During the Last 2 Years of Work Experience

Date: 9 July 2019

As the academic year comes to a close, a whole new generation of workforce is getting ready to enter the hyper-competitive job market. The constituents of this workforce are largely people who have worked really hard over the last few years and have been successful in securing a job right...
