Artificial Intelligence (AI) is significantly transforming the healthcare industry, addressing challenges in areas such as diagnostics and treatment planning. Large Language Models (LLMs) are emerging as a revolutionary tool in this sector, capable of deciphering and understanding complex health data. However, the intricate nature of medical data and the need for accuracy and efficiency in…
Proximal Policy Optimization (PPO), initially designed for continuous control tasks, is widely used in reinforcement learning (RL) applications, like fine-tuning generative models. However, PPO's effectiveness is based on a series of heuristics for stable convergence, like value networks and clipping, adding complexities in its implementation.
Adapting PPO to optimize complex modern generative models with billions of…
Multimodal large language models (MLLMs), which combine text and visual data processing, enhance the ability of artificial intelligence to understand and interact with the world. However, most open-source MLLMs are limited in their ability to process complex visual inputs and support multiple languages which can hinder their practical application.

Physics-Informed Neural Networks (PINNs), a blend of deep learning with physical laws, are increasingly used to resolve complex differential equations and signify a considerable leap in scientific computing and applied mathematics. The uniqueness of PINNs lies in embedding differential equations directly into the structure of neural networks, thus ensuring the adherence of solutions to fundamental…
The development and progress in the field of artificial intelligence (AI) are unending, with the recent emergence of the AI model, "gpt2-chatbot", generating significant interest within AI circles on Twitter. This model, known as a large language model (LLM), has incited considerable exploration and curiosity amongst AI developers and enthusiasts, who are constantly searching to…
French researchers have developed the first publicly available benchmark tool, 'DrBenchmark', to evaluate and standardize evaluation protocols for pre-trained masked language models (PLMs) in French, particularly in the biomedical field. Existing models lacked standardized protocols and comprehensive datasets, leading to inconsistent results and stalling progress in natural language processing (NLP) research.
The advent and advancement…
