SEC Chairman Gary Gensler emphasizes the importance of regulating AI in order to prevent a financial crisis. He expresses concerns about the potential for overreliance on AI tools by financial institutions, which could lead to a situation similar to the 2008 economic crisis. While the SEC is not against the use of AI, Gensler believes…
Researchers from Princeton have introduced Sheared-LLaMA models, which are smaller but stronger versions of large language models (LLMs), created through focused structured pruning. The method, which involves targeted structured pruning and dynamic batch loading, effectively reduces the size of LLMs while maintaining their performance. The Sheared-LLaMA models outperformed other LLMs of similar sizes in various…
UniSim, a universal simulator called UniSim, leverages diverse datasets to simulate realistic experiences triggered by human and agent actions. Its applications range from training embodied agents to enhancing video captioning models. UniSim aims to bridge the sim-to-real gap by training agents and machine intelligence models purely in simulation. While promising, future research should address adaptability…
Chinese search giant Baidu showcased its upgraded Ernie Bot chatbot at the Baidu World 2023 conference. Baidu CEO Robin Li claimed that Ernie Bot 4 is on par with OpenAI’s GPT-4 and demonstrated its abilities, including real-time novel writing, solving puzzles, creating posters and video commercials. While Ernie Bot focuses on Mandarin, it can respond…
Researchers propose a new dataset called Chop & Learn (ChopNLearn) to study compositional generalization in object recognition. They introduce two tasks, Compositional Image Generation and Compositional Action Recognition, to evaluate existing generative models and video recognition techniques.

Researchers propose Pairwise Proximal Policy Optimization (P3O), a new approach to Reinforcement Learning with Human Feedback (RLHF) that addresses the inconsistency between the reward learning and RL fine-tuning stages. By using a comparative training process, P3O improves alignment with human values and outperforms existing methods in terms of the KL-Reward frontier and GPT-4 win-rate. The…
Formal specifications, which use mathematical formulas to describe AI behavior, are not easily interpretable by humans, according to researchers at MIT Lincoln Laboratory. In an experiment, participants were asked to validate an AI agent’s plan for a virtual game based on formal specifications, and they were correct less than half of the time. The researchers…
The paper discusses the emergence of text-to-image diffusion models for image generation. It introduces “AlignProp,” a method to align diffusion models with reward functions through backpropagation during the denoising process. AlignProp outperforms alternative methods in optimizing diffusion models, achieving higher rewards in fewer training steps and improving both sampling efficiency and computational effectiveness.
