The Vision Language Model (VLM) is an advanced AI system that combines natural language understanding with image recognition. Researchers from Google have developed a new model called PaLI-3, which outperforms larger models in tasks like localization and text understanding. The study highlights the benefits of contrastive pre-training for VLMs and emphasizes the need for further…

Researchers have discovered that artificial neural networks designed to mimic human perception often exhibit invariances that do not match those found in human sensory perception. Model metamers, synthetic stimuli with similar activations to natural images or sounds, revealed significant differences between the invariances of computational models and human perception. This research highlights the challenges of…

UCSD and Microsoft researchers have developed COLDECO, a tool for inspecting code generated by large language models (LLMs) in spreadsheets. This tool aims to address the challenge of accuracy and trust in LLM-generated code by providing end-user inspection features, such as decomposing the solution into intermediate helper columns and highlighting interesting cases in summary rows.…
