Designing Decision Support Systems for Emergency Response: Challenges and Opportunities

no code implementations23 Feb 2022 Geoffrey Pettet, Hunter Baxter, Sayyed Mohsen Vazirizade, Hemant Purohit, Meiyi Ma, Ayan Mukhopadhyay, Abhishek Dubey

Designing effective emergency response management (ERM) systems to respond to incidents such as road accidents is a major problem faced by communities.

Practitioner-Centric Approach for Early Incident Detection Using Crowdsourced Data for Emergency Services

no code implementations3 Dec 2021 Yasas Senarath, Ayan Mukhopadhyay, Sayyed Mohsen Vazirizade, Hemant Purohit, Saideep Nannapaneni, Abhishek Dubey

First, we show how crowdsourced reports, ground-truth historical data, and other relevant determinants such as traffic and weather can be used together in a Convolutional Neural Network (CNN) architecture for early detection of emergency incidents.

Emergency Incident Detection from Crowdsourced Waze Data using Bayesian Information Fusion

1 code implementation10 Nov 2020 Yasas Senarath, Saideep Nannapaneni, Hemant Purohit, Abhishek Dubey

Crowdsourcing platforms such as Waze provides an opportunity to develop a rapid, `proactive' approach to collect data about incidents through crowd-generated observational reports.

Common-Knowledge Concept Recognition for SEVA

1 code implementation26 Mar 2020 Jitin Krishnan, Patrick Coronado, Hemant Purohit, Huzefa Rangwala

We build a common-knowledge concept recognition system for a Systems Engineer's Virtual Assistant (SEVA) which can be used for downstream tasks such as relation extraction, knowledge graph construction, and question-answering.

Entity Extraction using GAN graph construction +5

Unsupervised and Interpretable Domain Adaptation to Rapidly Filter Tweets for Emergency Services

1 code implementation4 Mar 2020 Jitin Krishnan, Hemant Purohit, Huzefa Rangwala

As deep networks struggle with sparse datasets, we show that this can be improved by sharing a base layer for multi-task learning and domain adversarial training.

Multi-Task Learning Unsupervised Domain Adaptation

Diversity-Based Generalization for Unsupervised Text Classification under Domain Shift

1 code implementation25 Feb 2020 Jitin Krishnan, Hemant Purohit, Huzefa Rangwala

At present, the state-of-the-art unsupervised domain adaptation approaches for subjective text classification problems leverage unlabeled target data along with labeled source data.

Evaluating Semantic Feature Representations to Efficiently Detect Hate Intent on Social Media

no code implementations ICSC 2020 Yasas Senarath, Hemant Purohit

We hypothesize that semantic features can help enrich the context representation of word senses in a social media post for machine learning algorithms.
