The paper “Bootstrap Your Own Variance: Understanding Model Uncertainty with SSL and Bayesian Methods” was accepted at the Self-Supervised Learning workshop at NeurIPS 2023. It proposes BYOV, combining BYOL SSL algorithm with BBB Bayesian method to estimate model posteriors, showing that BYOV’s predictive standard deviation aligns well with a Gaussian distribution.

Multimodal datasets play a crucial role in recent AI advancements like Stable Diffusion and GPT-4. However, their design is not as researched as model architectures or training algorithms. To tackle this, DataComp introduces a testbed for dataset experiments using 12.8 billion image-text pairs from Common Crawl, allowing participants to create and evaluate new datasets.

World models are AI systems aiming to understand and predict events in an environment. The Gen-2 video generative system is an early attempt but struggles with complex tasks. Challenges include creating accurate environment maps and simulating human behavior. Researchers work to improve adaptability and capabilities through metrics, with the goal of better simulating real-world scenarios.

A new method called COLMAP-Free 3D Gaussian Splatting (CF-3DGS) has been introduced by researchers from UC San Diego, NVIDIA, and UC Berkeley. It synthesizes views using video’s temporal continuity and explicit point cloud representation without the need for Structure-from-Motion (SfM) preprocessing. CF-3DGS optimizes camera pose and 3DGS jointly, making it suitable for video streams or…

Some LLMs may produce inaccurate responses due to hallucinations. Google DeepMind researchers propose FunSearch, a method to address this issue. It combines a pre-trained LLM with an evaluator to discover new knowledge by evolving low-scoring programs into high-scoring ones. This iterative process has significant potential for real-world applications and aims to expand functionalities to tackle…

Pennsylvania congressional candidate Shamaine Daniels is utilizing an AI robocaller, Ashley, to communicate with prospective voters in multiple languages. Ashley allows for two-way communication, answering questions about Daniels’ campaign and policies. The use of AI in political outreach raises questions about regulation and accountability, as AI technology continues to advance rapidly.
