Complex Logical Reasoning over Knowledge Graphs using Large Language Models

1 code implementation2 May 2023 Nurendra Choudhary, Chandan K. Reddy

Reasoning over knowledge graphs (KGs) is a challenging task that requires a deep understanding of the complex relationships between entities and the underlying logic of their relations.

Text Enriched Sparse Hyperbolic Graph Convolutional Networks

no code implementations6 Jul 2022 Nurendra Choudhary, Nikhil Rao, Karthik Subbian, Chandan K. Reddy

In TESH-GCN, we extract semantic node information, which successively acts as a connection signal to extract relevant nodes' local neighborhood and graph-level metapath features from the sparse adjacency tensor in a reformulated hyperbolic graph convolution layer.

A Unification Framework for Euclidean and Hyperbolic Graph Neural Networks

1 code implementation9 Jun 2022 Mehrdad Khatir, Nurendra Choudhary, Sutanay Choudhury, Khushbu Agarwal, Chandan K. Reddy

Such an approach enables us to propose a hyperbolic normalization layer and to further simplify the entire hyperbolic model to a Euclidean model cascaded with our hyperbolic normalization layer.

Towards Scalable Hyperbolic Neural Networks using Taylor Series Approximations

no code implementations7 Jun 2022 Nurendra Choudhary, Chandan K. Reddy

However, their adoption in practice remains restricted due to (i) non-scalability on accelerated deep learning hardware, (ii) vanishing gradients due to the closure of hyperbolic space, and (iii) information loss due to frequent mapping between local tangent space and fully hyperbolic space.

Probabilistic Entity Representation Model for Reasoning over Knowledge Graphs

1 code implementation NeurIPS 2021 Nurendra Choudhary, Nikhil Rao, Sumeet Katariya, Karthik Subbian, Chandan K. Reddy

Current approaches employ spatial geometries such as boxes to learn query representations that encompass the answer entities and model the logical operations of projection and intersection.

Self-Supervised Hyperboloid Representations from Logical Queries over Knowledge Graphs

1 code implementation23 Dec 2020 Nurendra Choudhary, Nikhil Rao, Sumeet Katariya, Karthik Subbian, Chandan K. Reddy

Promising approaches to tackle this problem include embedding the KG units (e. g., entities and relations) in a Euclidean space such that the query embedding contains the information relevant to its results.

Cross-Lingual Task-Specific Representation Learning for Text Classification in Resource Poor Languages

no code implementations10 Jun 2018 Nurendra Choudhary, Rajat Singh, Manish Shrivastava

The model learns the representation of resource-poor and resource-rich sentences in a common space by using the similarity between their assigned annotation tags.

Contrastive Learning of Emoji-based Representations for Resource-Poor Languages

no code implementations3 Apr 2018 Nurendra Choudhary, Rajat Singh, Ishita Bindlish, Manish Shrivastava

The model learns the representations of resource-poor and resource-rich language in a common emoji space by using a similarity metric based on the emojis present in sentences from both languages.

Sentiment Analysis of Code-Mixed Languages leveraging Resource Rich Languages

1 code implementation3 Apr 2018 Nurendra Choudhary, Rajat Singh, Ishita Bindlish, Manish Shrivastava

Code-mixed data is an important challenge of natural language processing because its characteristics completely vary from the traditional structures of standard languages.
