Cross-Platform Hate Speech Detection with Weakly Supervised Causal Disentanglement

no code implementations17 Apr 2024 Paras Sheth, Tharindu Kumarage, Raha Moraffah, Aman Chadha, Huan Liu

Content moderation faces a challenging task as social media's ability to spread hate speech contrasts with its role in promoting global connectivity.

Towards Interpretable Hate Speech Detection using Large Language Model-extracted Rationales

no code implementations19 Mar 2024 Ayushi Nirmal, Amrita Bhattacharjee, Paras Sheth, Huan Liu

Although social media platforms are a prominent arena for users to engage in interpersonal discussions and express opinions, the facade and anonymity offered by social media may allow users to spew hate speech and offensive content.

Causal Feature Selection for Responsible Machine Learning

no code implementations5 Feb 2024 Raha Moraffah, Paras Sheth, Saketh Vishnubhatla, Huan Liu

This survey focuses on the current study of causal feature selection: what it is and how it can reinforce the four aspects of responsible ML.

How Reliable Are AI-Generated-Text Detectors? An Assessment Framework Using Evasive Soft Prompts

no code implementations8 Oct 2023 Tharindu Kumarage, Paras Sheth, Raha Moraffah, Joshua Garland, Huan Liu

The novel universal evasive prompt is achieved in two steps: First, we create an evasive soft prompt tailored to a specific PLM through prompt tuning; and then, we leverage the transferability of soft prompts to transfer the learned evasive soft prompt from one PLM to another.

Causality Guided Disentanglement for Cross-Platform Hate Speech Detection

1 code implementation3 Aug 2023 Paras Sheth, Tharindu Kumarage, Raha Moraffah, Aman Chadha, Huan Liu

By disentangling input into platform-dependent features (useful for predicting hate targets) and platform-independent features (used to predict the presence of hate), we learn invariant representations resistant to distribution shifts.

UPREVE: An End-to-End Causal Discovery Benchmarking System

no code implementations25 Jul 2023 Suraj Jyothi Unni, Paras Sheth, Kaize Ding, Huan Liu, K. Selcuk Candan

Discovering causal relationships in complex socio-behavioral systems is challenging but essential for informed decision-making.

Quantifying the Echo Chamber Effect: An Embedding Distance-based Approach

1 code implementation10 Jul 2023 Faisal Alatawi, Paras Sheth, Huan Liu

To facilitate measuring distances between users, we propose EchoGAE, a self-supervised graph autoencoder-based user embedding model that leverages users' posts and the interaction graph to embed them in a manner that reflects their ideological similarity.

PEACE: Cross-Platform Hate Speech Detection- A Causality-guided Framework

1 code implementation15 Jun 2023 Paras Sheth, Tharindu Kumarage, Raha Moraffah, Aman Chadha, Huan Liu

Hate speech detection refers to the task of detecting hateful content that aims at denigrating an individual or a group based on their religion, gender, sexual orientation, or other characteristics.

Estimating Topic Exposure for Under-Represented Users on Social Media

no code implementations7 Aug 2022 Mansooreh Karami, Ahmadreza Mosallanezhad, Paras Sheth, Huan Liu

To reduce the bias induced by the contributors, in this work, we focus on highlighting the engagers' contributions in the observed data as they are more likely to contribute when compared to lurkers, and they comprise a bigger population as compared to the contributors.

CoVaxNet: An Online-Offline Data Repository for COVID-19 Vaccine Hesitancy Research

1 code implementation30 Jun 2022 Bohan Jiang, Paras Sheth, Baoxin Li, Huan Liu

Despite the astonishing success of COVID-19 vaccines against the virus, a substantial proportion of the population is still hesitant to be vaccinated, undermining governmental efforts to control the virus.

Causal Disentanglement with Network Information for Debiased Recommendations

no code implementations14 Apr 2022 Paras Sheth, Ruocheng Guo, Lu Cheng, Huan Liu, K. Selçuk Candan

Aside from the user conformity, aspects of confounding such as item popularity present in the network information is also captured in our method with the aid of \textit{causal disentanglement} which unravels the learned representations into independent factors that are responsible for (a) modeling the exposure of an item to the user, (b) predicting the ratings, and (c) controlling the hidden confounders.

Evaluation Methods and Measures for Causal Learning Algorithms

no code implementations7 Feb 2022 Lu Cheng, Ruocheng Guo, Raha Moraffah, Paras Sheth, K. Selcuk Candan, Huan Liu

To bridge from conventional causal inference (i. e., based on statistical methods) to causal learning with big data (i. e., the intersection of causal inference and machine learning), in this survey, we review commonly-used datasets, evaluation methods, and measures for causal learning using an evaluation pipeline similar to conventional machine learning.

Causal Inference for Time series Analysis: Problems, Methods and Evaluation

no code implementations11 Feb 2021 Raha Moraffah, Paras Sheth, Mansooreh Karami, Anchit Bhattacharya, Qianru Wang, Anique Tahir, Adrienne Raglin, Huan Liu

In this paper, we focus on two causal inference tasks, i. e., treatment effect estimation and causal discovery for time series data, and provide a comprehensive review of the approaches in each task.
