➡️ UCI and Harvard Researchers Introduce TalkToModel that Explains Machine Learning Models to its Users

This paper proposes TalkToModel, an interactive dialogue system aimed at demystifying machine learning models through natural language conversations. Comprising three main components—an adaptive dialogue engine, an execution component, and a conversational interface—TalkToModel simplifies the process of model explanation. The adaptive dialogue engine interprets user queries and crafts meaningful responses, while the execution component generates the explanations used in these conversations. Real-world evaluations show promising results; 73% of healthcare workers preferred TalkToModel over existing systems for understanding disease prediction models, and 85% of ML professionals found it easier to use. The system thus effectively addresses the challenge of model explainability.

➡️  Google DeepMind Research Explores the Puzzling Phenomenon of Grokking in Neural Networks: Unveiling the Interplay Between Memorization and Generalization

This paper addresses this phenomenon, termed "grokking," by proposing that tasks can have both a "generalizing solution" and a "memorizing solution." The generalizing solution is harder to learn but is more efficient in terms of computational resources. The authors hypothesize that as training datasets grow, memorizing becomes inefficient while generalizing circuits remain efficient. They identify a "critical dataset size" at which both approaches are equally efficient. The paper confirms this theory through four novel predictions and introduces two surprising behaviors: "ungrokking," where the network's test accuracy regresses, and "semi-grokking," where delayed partial generalization occurs.

➡️  Researchers at Heriot-Watt University and Alana AI Propose FurChat: A New Embodied Conversational Agent Based on Large Language Models

How can we develop an embodied conversational agent that goes beyond basic interactions to provide engaging and informative dialogue as a receptionist? The paper presents a system that addresses this by deploying a large language model (LLM) on a Furhat robot to serve as a receptionist at the National Robotarium. The Furhat robot is uniquely suited for this task as it is capable of delivering both verbal and non-verbal cues, thus offering a more holistic conversational experience. The system uses GPT-3.5, a state-of-the-art language model, for generating a mix of domain-specific and open-domain conversations along with facial expressions. This is achieved through prompt engineering, enabling the robot to provide visitors with information about facilities, research, news, and upcoming events in a natural and engaging manner.

➡️ This Paper by Alibaba Group Introduces FederatedScope-LLM: A Comprehensive Package for Fine-Tuning LLMs in Federated Learning

How can large language models (LLMs) be effectively fine-tuned in a federated learning (FL) environment where data privacy is a concern among different entities? This paper addresses the limitations in existing FL frameworks that struggle to support the fine-tuning of LLMs due to challenges such as high communication and computational costs, complex data preparation, and diverse information protection needs. The paper introduces FS-LLM, a specialized package that offers an end-to-end benchmarking pipeline for dataset preprocessing, federated fine-tuning, and performance evaluation. The package also includes parameter-efficient fine-tuning algorithms and versatile programming interfaces designed for low resource consumption. The researchers conducted extensive experiments to validate the FS-LLM framework, providing valuable insights and benchmarks for the research community.

➡️ Meet NExT-GPT: An End-to-End General-Purpose Any-to-Any Multimodal Large Language Models (MM-LLMs)

This paper introduces NExT-GPT, an end-to-end general-purpose Multimodal Large Language Model (MM-LLM) designed to solve this problem. NExT-GPT integrates traditional large language models with multimodal adaptors and diffusion decoders, allowing it to handle arbitrary combinations of input and output modalities. Remarkably, the model is fine-tuned using only 1% of the parameters in certain projection layers, making it cost-effective to train. It also features a unique modality-switching instruction tuning (MosIT) mechanism and a manually curated high-quality dataset to enhance its cross-modal semantic understanding and content generation capabilities. This research opens the door for more human-like AI systems capable of universal modality processing.
