Foundation Models of Scientific Knowledge for Chemistry: Opportunities, Challenges and Lessons Learned

1 code implementation BigScience (ACL) 2022 Sameera Horawalavithana, Ellyn Ayton, Shivam Sharma, Scott Howland, Megha Subramanian, Scott Vasquez, Robin Cosbey, Maria Glenski, Svitlana Volkova

Foundation models pre-trained on large corpora demonstrate significant gains across many natural language processing tasks and domains e. g., law, healthcare, education, etc.

Evaluating and Explaining Natural Language Generation with GenX

1 code implementation NAACL (DaSH) 2021 Kayla Duskin, Shivam Sharma, Ji Young Yun, Emily Saldanha, Dustin Arendt

Current methods for evaluation of natural language generation models focus on measuring text quality but fail to probe the model creativity, i. e., its ability to generate novel but coherent text sequences not seen in the training corpus.

Recent Advances in Hate Speech Moderation: Multimodality and the Role of Large Models

no code implementations30 Jan 2024 Ming Shan Hee, Shivam Sharma, Rui Cao, Palash Nandi, Tanmoy Chakraborty, Roy Ka-Wei Lee

In the evolving landscape of online communication, moderating hate speech (HS) presents an intricate challenge, compounded by the multimodal nature of digital content.

Transparency in Sleep Staging: Deep Learning Method for EEG Sleep Stage Classification with Model Interpretability

no code implementations10 Sep 2023 Shivam Sharma, Suvadeep Maiti, S. Mythirayee, Srijithesh Rajendran, Raju Surampudi Bapi

A distinctive aspect of this study is the adaptation of GradCam for sleep staging, marking the first instance of an explainable DL model in this domain with alignment of its decision-making with sleep expert's insights.

MEMEX: Detecting Explanatory Evidence for Memes via Knowledge-Enriched Contextualization

1 code implementation25 May 2023 Shivam Sharma, Ramaneswaran S, Udit Arora, Md. Shad Akhtar, Tanmoy Chakraborty

In this work, we propose a novel task, MEMEX - given a meme and a related document, the aim is to mine the context that succinctly explains the background of the meme.

Characterizing the Entities in Harmful Memes: Who is the Hero, the Villain, the Victim?

no code implementations26 Jan 2023 Shivam Sharma, Atharva Kulkarni, Tharun Suresh, Himanshi Mathur, Preslav Nakov, Md. Shad Akhtar, Tanmoy Chakraborty

A common problem associated with meme comprehension lies in detecting the entities referenced and characterizing the role of each of these entities.

Semantic Role Labeling

Domain-aware Self-supervised Pre-training for Label-Efficient Meme Analysis

no code implementations29 Sep 2022 Shivam Sharma, Mohd Khizir Siddiqui, Md. Shad Akhtar, Tanmoy Chakraborty

Existing self-supervised learning strategies are constrained to either a limited set of objectives or generic downstream tasks that predominantly target uni-modal applications.

Representation Learning Self-Supervised Learning

Quantum-Inspired Tensor Neural Networks for Partial Differential Equations

no code implementations3 Aug 2022 Raj Patel, Chia-Wei Hsing, Serkan Sahin, Saeed S. Jahromi, Samuel Palmer, Shivam Sharma, Christophe Michel, Vincent Porte, Mustafa Abid, Stephane Aubert, Pierre Castellani, Chi-Guhn Lee, Samuel Mugel, Roman Orus

We demonstrate that TNN provide significant parameter savings while attaining the same accuracy as compared to the classical Dense Neural Network (DNN).

DISARM: Detecting the Victims Targeted by Harmful Memes

1 code implementation Findings (NAACL) 2022 Shivam Sharma, Md. Shad Akhtar, Preslav Nakov, Tanmoy Chakraborty

Finally, we show that DISARM is interpretable and comparatively more generalizable and that it can reduce the relative error rate for harmful target identification by up to 9 points absolute over several strong multimodal rivals.

Detecting and Understanding Harmful Memes: A Survey

1 code implementation9 May 2022 Shivam Sharma, Firoj Alam, Md. Shad Akhtar, Dimitar Dimitrov, Giovanni Da San Martino, Hamed Firooz, Alon Halevy, Fabrizio Silvestri, Preslav Nakov, Tanmoy Chakraborty

One interesting finding is that many types of harmful memes are not really studied, e. g., such featuring self-harm and extremism, partly due to the lack of suitable datasets.

EXPERT: Public Benchmarks for Dynamic Heterogeneous Academic Graphs

1 code implementation14 Apr 2022 Sameera Horawalavithana, Ellyn Ayton, Anastasiya Usenko, Shivam Sharma, Jasmine Eshun, Robin Cosbey, Maria Glenski, Svitlana Volkova

Machine learning models that learn from dynamic graphs face nontrivial challenges in learning and inference as both nodes and edges change over time.

Attentive Recurrent Tensor Model for Community Question Answering

no code implementations21 Jan 2018 Gaurav Bhatt, Shivam Sharma, Balasubramanian Raman

Further, we use the tensor parameters to introduce a 3-way interaction between question, answer and external features in vector space.
