Generalizing Cooperative Eco-driving via Multi-residual Task Learning

no code implementations7 Mar 2024 Vindula Jayawardana, Sirui Li, Cathy Wu, Yashar Farid, Kentaro Oguchi

To address this, we introduce Multi-residual Task Learning (MRTL), a generic learning framework based on multi-task learning that, for a set of task scenarios, decomposes the control into nominal components that are effectively solved by conventional control methods and residual terms which are solved using learning.

Model-free Learning of Corridor Clearance: A Near-term Deployment Perspective

no code implementations16 Dec 2023 Dajiang Suo, Vindula Jayawardana, Cathy Wu

To overcome these challenges and enhance real-world applicability in near-term, we propose a model-free approach employing deep reinforcement learning (DRL) for designing CAV control strategies, showing its reduced overhead in designing and greater scalability and performance compared to model-based methods.

The Impact of Task Underspecification in Evaluating Deep Reinforcement Learning

no code implementations16 Oct 2022 Vindula Jayawardana, Catherine Tang, Sirui Li, Dajiang Suo, Cathy Wu

We show that in comparison to evaluating DRL methods on select MDP instances, evaluating the MDP family often yields a substantially different relative ranking of methods, casting doubt on what methods should be considered state-of-the-art.

Learning Eco-Driving Strategies at Signalized Intersections

no code implementations26 Apr 2022 Vindula Jayawardana, Cathy Wu

Signalized intersections in arterial roads result in persistent vehicle idling and excess accelerations, contributing to fuel consumption and CO2 emissions.

The Braess Paradox in Dynamic Traffic

no code implementations7 Mar 2022 Dingyi Zhuang, Yuzhu Huang, Vindula Jayawardana, Jinhua Zhao, Dajiang Suo, Cathy Wu

The Braess's Paradox (BP) is the observation that adding one or more roads to the existing road network will counter-intuitively increase traffic congestion and slow down the overall traffic flow.

Fleet management for ride-pooling with meeting points at scale: a case study in the five boroughs of New York City

no code implementations25 Apr 2021 Motahare Mounesan, Vindula Jayawardana, Yaocheng Wu, Samitha Samaranayake, Huy T. Vo

To the best of our knowledge, STaRS+ is the first study on the RPMP that can solve large-scale instances on the order of the entire NYC metro area.

Legal Document Retrieval using Document Vector Embeddings and Deep Learning

no code implementations27 May 2018 Keet Sugathadasa, Buddhi Ayesha, Nisansa de Silva, Amal Shehan Perera, Vindula Jayawardana, Dimuthu Lakmal, Madhavi Perera

The ensemble model built in this study, shows a significantly higher accuracy level, which indeed proves the need for incorporation of domain specific semantic similarity measures into the information retrieval process.

Semi-Supervised Instance Population of an Ontology using Word Vector Embeddings

no code implementations9 Sep 2017 Vindula Jayawardana, Dimuthu Lakmal, Nisansa de Silva, Amal Shehan Perera, Keet Sugathadasa, Buddhi Ayesha, Madhavi Perera

With the use of word embeddings in the field of natural language processing, it became a popular topic due to its ability to cope up with semantic sensitivity.
