  • Action Speaks Louder Than Words Trillion-Parameter Sequential Transducers for Generative Recommendations
    Feb 20 2025

    In today’s episode, we’re diving into the fascinating world of model merging—a technique that allows multiple AI models to be combined, often enhancing their capabilities without the need for costly retraining. Our focus? A groundbreaking paper titled "Do Merged Models Copy or Compose? Evaluating the Transfer of Capabilities in Model Merging" by researchers exploring the inner workings of this emerging technique.

    We'll be discussing:

    🔹 What is model merging? Why it's gaining traction in AI research.

    🔹 Do merged models simply copy knowledge, or can they create something new?

    🔹 How does merging affect generalization, robustness, and performance?

    🔹 Real-world implications—from adapting models across different domains to fine-tuning AI with fewer resources.

  • Modern Recommender Systems Using Generative Models (Gen-RecSys)
    Feb 16 2025

    In this episode, we delve into the transformative impact of Generative Models on modern Recommender Systems (RS), as detailed in the comprehensive survey titled "A Review of Modern Recommender Systems Using Generative Models (Gen-RecSys)". This multidisciplinary study explores how traditional RS, which primarily relied on user-item rating histories, are evolving through the integration of advanced generative techniques.

    Key Discussion Points:

    • Interaction-Driven Generative Models: We examine how models like Generative Adversarial Networks (GANs) and Variational Autoencoders (VAEs) are utilized to capture complex user-item interactions, enabling the generation of personalized recommendations beyond historical data.
    • Large Language Models (LLMs) in Natural Language Recommendations: The episode highlights the role of LLMs, such as ChatGPT and Gemini, in understanding and generating human-like text, facilitating conversational recommendations and enhancing user engagement through natural language interfaces.
    • Multimodal Models for Rich Content Integration: We discuss the incorporation of multimodal data—text, images, and videos—into RS, allowing for a more holistic understanding of user preferences and the ability to recommend diverse content types.
    • Evaluation Paradigms and Ethical Considerations: The survey emphasizes the importance of developing new evaluation frameworks to assess the performance and societal impact of Gen-RecSys, addressing challenges such as bias, fairness, and user privacy.

    Join us as we explore these advancements, shedding light on the future directions of recommender systems in the era of generative AI.
