MOVIEAGENT: LONG CONSISTENT MOVIE GENERATION

This system strings together multiple generative modalities and uses persona-based prompting to encourage consistency and accurate results. It then uses the Stable Diffusion video model to create and stitch frames together. This likely would be improved using Wan.

LARGE LANGUAGE AND VISION EMBEDDING MODELS WITH HARDNESS-WEIGHTED CONTRASTIVE LEARNING

Building embedding models for vision and language tasks using a contrastive loss can often lead these models to struggle on hard negative pairs. This work proposes a regularization strategy and observed a substantial improvement in difficult retrieval problems. The method also scales to zero shot video retrieval.

GENERALIZED DISCRETE DIFFUSION

This work extends diffusion on discrete data, such as text, with a generalized denoising process and a slightly improved masking scheme. This combination makes training efficient and gives the model the ability to correct its own output.

THE TECHCRUNCH AI GLOSSARY

This article provides definitions for key AI terminology, including "AI agents," chain-of-thought reasoning, deep learning, and large language models (LLMs). Deep learning is described as a subset of machine learning inspired by the neural pathways in the human brain, and LLMs are described as neural networks enabling AI assistants like ChatGPT. Fine-tuning and the importance of weights in optimizing AI models are also discussed.
