Graph Convolutional Networks (GCNs) have become integral in analyzing complex graph-structured data. These networks capture the relationships between nodes and their attributes, making them indispensable in domains like social network analysis, biology, and chemistry. By leveraging graph structures, GCNs enable node classification and link prediction tasks, fostering advancements in scientific and industrial applications. Large-scale graph… →

The study of collective decision-making in biological and artificial systems addresses critical challenges in understanding how groups achieve consensus through simple interactions. Such processes underpin behaviors in animal herds, human groups, and robotic swarms. Recent advances in neuroscience have explored how neural dynamics, oscillations, and phase-locking mechanisms facilitate these decisions in biological systems. However, the… →

Multimodal large language models (MLLMs) showed impressive results in various vision-language tasks by combining advanced auto-regressive language models with visual encoders. These models generated responses using visual and text inputs, with visual features from an image encoder processed before the text embeddings. However, there remains a big gap in understanding the inner mechanisms behind how… →

Ensuring AI models provide faithful and reliable explanations of their decision-making processes is still challenging. Faithfulness in the sense of explanations faithfully representing the underlying logic of a model prevents false confidence in AI systems, which is critical for healthcare, finance, and policymaking. Existing paradigms for interpretability—intrinsic (focused on inherently interpretable models) and post-hoc (providing… →

In the age of data-driven decision-making, access to high-quality and diverse datasets is crucial for training reliable machine learning models. However, acquiring such data often comes with numerous challenges, ranging from privacy concerns to the scarcity of domain-specific labeled samples. Traditional data collection and annotation processes are resource-intensive, slow, and may suffer from bias or… →

Integration of Reinforcement Learning RL with large language models catalyzes LLM’s performance on distinct specialty tasks such as robotics control or natural language processing that require sequential decision-making. Offline RL is one such technique in the spotlight today that works with static datasets without additional engagements. However, despite its utility in single-turn scenarios, Offline RL… →

Recommender systems (RS) are essential for generating personalized suggestions based on user preferences, historical interactions, and item attributes. These systems enhance user experience by helping individuals discover relevant content, such as movies, music, books, or products tailored to their interests. Popular platforms like Netflix, Amazon, and YouTube leverage RS to deliver high-quality recommendations that improve… →

In the quest to develop new drugs, the journey from laboratory research to clinical application is complex and expensive. The drug discovery process involves multiple stages, including target identification, drug screening, lead optimization, and clinical trials. Each stage requires a substantial investment of time and resources, leading to a high risk of failure. More specifically,… →
