Salesforce AI Research has announced the launch of Moirai, an AI model trained to do universal forecasting. They say it was trained on Large-scale Open Time Series Archive (LOTSA), a massive open time series dataset with 27 billion observations across nine domains, and has outshone other models in forecasting tests. Fields experimented in include forecasting in energy, transport, climate, sales, economics, and healthcare.

Hugging Face has compiled and shared a collection of tools aimed at identifying and preventing the proliferation of AI-generated "deepfake" content. Among these are watermarking tools and techniques known as "Photoguard" for protecting images from generative model manipulation, LLM Watermarking, and image "poisoning," which is a strategy intended to disrupt the development of facial recognition models.

Jascha Sohl-Dickstein, a research scientist at Google, revealed his discovery of a fractal pattern in the hyperparameter landscapes of neural network training. (Parameters are derived from training data; the hyperparameters are externally imposed during configuration and optimization.) Sohl-Dickstein suggests that this fractal behavior can demonstrate the challenges of meta-learning, as minor adjustments in hyperparameters could lead to considerable changes in training dynamics.

StabilityAI has launched Stable Cascade, a new text-to-image model, which the company says significantly reduces costs by 16 times when compared to similar-sized Stable Diffusion models. The model was built on the Würstchen architecture, which was released in a research paper on Arxiv in September 2023. It reportedly excels in prompt alignment and aesthetic quality based on several tests against models such as Playground v2 and SDXL.
