The Ubiquity of Diffusiophoresis: Exploring Human Population Dynamics While Including Concentration Gradient-Driven Advection

no code implementations • 11 Oct 2023 • Benjamin M. Alessio, Ankur Gupta

Diffusiophoresis, which refers to the movement of entities driven by gradients in the concentration of attractants, is observable in colloids and chemotactic bacteria.

Unsupervised Contextualized Document Representation

1 code implementation • EMNLP (sustainlp) 2021 • Ankur Gupta, Vivek Gupta

In this paper, we address this issue by proposing SCDV+BERT(ctxd), a simple and effective unsupervised representation that combines contextualized BERT (Devlin et al., 2019) based word embedding for word sense disambiguation with SCDV soft clustering approach.

BreakingBERT@IITK at SemEval-2021 Task 9: Statement Verification and Evidence Finding with Tables

no code implementations • SEMEVAL 2021 • Aditya Jindal, Ankur Gupta, Jaya Srivastava, Preeti Menghwani, Vijit Malik, Vishesh Kaushik, Ashutosh Modi

There are two subtasks, in which given a table and a statement/fact, the subtask A is to determine whether the statement is inferred from the tabular data and the subtask B is to determine which cells in the table provide evidence for the former subtask.
