Real-world networks, such as those in biomedical and multi-omics datasets, often present complex structures characterized by multiple types of nodes and edges, making them heterogeneous or multiplex. Most graph-based learning techniques fail to handle such intricate networks because of their intrinsic complexity, even though graph neural networks have been quite in vogue and garnered significant… →

Function calling has emerged as a transformative capability in AI systems, enabling language models to interact with external tools through structured JSON object generation. However, current methodologies face critical challenges in comprehensively simulating real-world interaction scenarios. Existing approaches predominantly focus on generating tool-specific call messages, overlooking the nuanced requirements of human-AI conversational interactions. The complexity… →

Diffusion models have pulled ahead of others in text-to-image generation. With continuous research in this field over the past year, we can now generate high-resolution, realistic images that are indistinguishable from authentic images.  However, with the increasing quality of the hyperrealistic images model, parameters are also escalating, and this trend results in high training and… →

Red teaming plays a pivotal role in evaluating the risks associated with AI models and systems.
