Tackling Fake News Detection by Continually Improving Social Context Representations using Graph Neural Networks
We view fake news detection as reasoning over the relations between sources, articles they publish, and engaging users on social media in a graph framework.
Tackling Fake News Detection by Interactively Learning Representations using Graph Neural Networks
Easy access, variety of content, and fast widespread interactions are some of the reasons that have made social media increasingly popular in today’s society.
Talking Point based Ideological Discourse Analysis in News Events
Analyzing ideological discourse even in the age of LLMs remains a challenge, as these models often struggle to capture the key elements that shape real-world narratives.
Toward Holistic Evaluation of Recommender Systems Powered by Generative Models
First, we categorize the evaluation challenges of Gen-RecSys into two groups: (i) existing concerns that are exacerbated by generative outputs (e. g., bias, privacy) and (ii) entirely new risks (e. g., item hallucinations, contradictory explanations).
Building a Mind Palace: Structuring Environment-Grounded Semantic Graphs for Effective Long Video Analysis with LLMs
Long-form video understanding with Large Vision Language Models is challenged by the need to analyze temporally dispersed yet spatially concentrated key moments within limited context windows.

We also introduce a relation regularization method to further disentangle image transformation features from irrelevant contents in exemplar images.
STAR: A Simple Training-free Approach for Recommendations using Large Language Models
In this paper, we propose a Simple Training-free Approach for Recommendation (STAR), a framework that utilizes LLMs and can be applied to various recommendation tasks without the need for fine-tuning, while maintaining high quality recommendation performance.

Using RL to Identify Divisive Perspectives Improves LLMs Abilities to Identify Communities on Social Media
The large scale usage of social media, combined with its significant impact, has made it increasingly important to understand it.
Assessing and Verifying Task Utility in LLM-Powered Applications
The rapid development of Large Language Models (LLMs) has led to a surge in applications that facilitate collaboration among multiple agents, assisting humans in their daily tasks.
Aligning Large Language Models with Recommendation Knowledge
Operations such as Masked Item Modeling (MIM) and Bayesian Personalized Ranking (BPR) have found success in conventional recommender systems.
HyperMix: Out-of-Distribution Detection and Classification in Few-Shot Settings
Out-of-distribution (OOD) detection is an important topic for real-world machine learning systems, but settings with limited in-distribution samples have been underexplored.

Meta-Learned Attribute Self-Interaction Network for Continual and Generalized Zero-Shot Learning
Zero-shot learning (ZSL) is a promising approach to generalizing a model to categories unseen during training by leveraging class attributes, but challenges remain.
Interactively Learning Social Media Representations Improves News Source Factuality Detection
The rise of social media has enabled the widespread propagation of fake news, text that is published with an intent to spread misinformation and sway beliefs.
An Interactive Framework for Profiling News Media Sources
The recent rise of social media has led to the spread of large amounts of fake and biased news, content published with the intent to sway beliefs.
Density Weighting for Multi-Interest Personalized Recommendation
When the data distribution is highly skewed, the gains observed by learning multiple representations diminish since the model dominates on head items/interests, leading to poor performance on tail items.
Better Generalization with Semantic IDs: A Case Study in Ranking for Recommendations
To strike a good balance of memorization and generalization, we propose to use Semantic IDs -- a compact discrete item representation learned from frozen content embeddings using RQ-VAE that captures the hierarchy of concepts in items -- as a replacement for random item ids.
Do LLMs Understand User Preferences? Evaluating LLMs On User Rating Prediction
In this paper, we conduct a thorough examination of both CF and LLMs within the classic task of user rating prediction, which involves predicting a user's rating for a candidate item based on their past ratings.
Improving Grounded Language Understanding in a Collaborative Environment by Interacting with Agents Through Help Feedback
We explore multiple types of help players can give to the AI to guide it and analyze the impact of this help in AI behavior, resulting in performance improvements.

Weight pruning is among the most popular approaches for compressing deep convolutional neural networks.
Pseudo-OOD training for robust language models
The model is fine-tuned by introducing a new regularization loss that separates the embeddings of IND and OOD data, which leads to significant gains on the OOD prediction task during testing.

Continual Learning using a Bayesian Nonparametric Dictionary of Weight Factors
Naively trained neural networks tend to experience catastrophic forgetting in sequential task settings, where data from previous tasks are unavailable.
Graph Representation Learning via Ladder Gamma Variational Autoencoders
In addition to leveraging the representational power of multiple layers of stochastic variables via the ladder VAE architecture, our framework offers the following benefits: (1) Unlike existing ladder VAE architectures based on real-valued latent variables, the gamma-distributed latent variables naturally result in non-negativity and sparsity of the learned embeddings, and facilitate their direct interpretation as membership of nodes into (possibly multiple) communities/topics; (2) A novel recognition model for our gamma ladder VAE architecture allows fast inference of node embeddings; and (3) The framework also extends naturally to incorporate node side information (features and/or labels).
