Predicting Drug-Drug Interactions from Heterogeneous Data: An Embedding Approach

no code implementations19 Mar 2021 Devendra Singh Dhami, Siwen Yan, Gautam Kunapuli, David Page, Sriraam Natarajan

Predicting and discovering drug-drug interactions (DDIs) using machine learning has been studied extensively.

Multi-Robot Routing with Time Windows: A Column Generation Approach

no code implementations16 Mar 2021 Naveed Haghani, Jiaoyang Li, Sven Koenig, Gautam Kunapuli, Claudio Contardo, Amelia Regan, Julian Yarkony

We formulate the problem as a weighted set packing problem where the elements in consideration are items on the warehouse floor that can be picked up and delivered within specified time windows.

Integer Programming for Multi-Robot Planning: A Column Generation Approach

no code implementations8 Jun 2020 Naveed Haghani, Jiaoyang Li, Sven Koenig, Gautam Kunapuli, Claudio Contardo, Julian Yarkony

We consider the problem of coordinating a fleet of robots in a warehouse so as to maximize the reward achieved within a time limit while respecting problem and robot specific constraints.

Knowledge Graph Alignment using String Edit Distance

no code implementations13 Mar 2020 Navdeep Kaur, Gautam Kunapuli, Sriraam Natarajan

In this work, we propose a novel knowledge graph alignment technique based upon string edit distance that exploits the type information between entities and can find similarity between relations of any arity

Non-Parametric Learning of Lifted Restricted Boltzmann Machines

no code implementations9 Jan 2020 Navdeep Kaur, Gautam Kunapuli, Sriraam Natarajan

We consider the problem of discriminatively learning restricted Boltzmann machines in the presence of relational data.

Non-Parametric Learning of Gaifman Models

no code implementations2 Jan 2020 Devendra Singh Dhami, Siwen Yan, Gautam Kunapuli, Sriraam Natarajan

We consider the problem of structure learning for Gaifman models and learn relational features that can be used to derive feature representations from a knowledge base.

Beyond Textual Data: Predicting Drug-Drug Interactions from Molecular Structure Images using Siamese Neural Networks

no code implementations14 Nov 2019 Devendra Singh Dhami, Siwen Yan, Gautam Kunapuli, David Page, Sriraam Natarajan

Predicting and discovering drug-drug interactions (DDIs) is an important problem and has been studied extensively both from medical and machine learning point of view.

Neural Networks for Relational Data

1 code implementation28 Aug 2019 Navdeep Kaur, Gautam Kunapuli, Saket Joshi, Kristian Kersting, Sriraam Natarajan

While deep networks have been enormously successful over the last decade, they rely on flat-feature vector representations, which makes them unsuitable for richly structured domains such as those arising in applications like social network analysis.

Knowledge-augmented Column Networks: Guiding Deep Learning with Advice

no code implementations31 May 2019 Mayukh Das, Devendra Singh Dhami, Yang Yu, Gautam Kunapuli, Sriraam Natarajan

Recently, deep models have had considerable success in several tasks, especially with low-level representations.

Human-Guided Column Networks: Augmenting Deep Learning with Advice

no code implementations ICLR 2019 Mayukh Das, Yang Yu, Devendra Singh Dhami, Gautam Kunapuli, Sriraam Natarajan

While extremely successful in several applications, especially with low-level representations; sparse, noisy samples and structured domains (with multiple objects and interactions) are some of the open challenges in most deep models.

Human-Guided Learning of Column Networks: Augmenting Deep Learning with Advice
