CONTEXT IS KEY: A BENCHMARK FOR FORECASTING WITH ESSENTIAL TEXTUAL INFORMATION

The best and most commonly used time series forecasting methods rely entirely on numerical features associated with the time series. However, they rarely use textual or semantic information about the task itself (e.g., are you predicting electric prices or customer churn). When prompted with this textual information in context, language models surpass all tested time series forecasting methods substantially across a wide range of carefully decontaminated tasks.

PROMPTING DEPTH ANYTHING FOR 4K RESOLUTION ACCURATE METRIC DEPTH ESTIMATION

By using low cost LiDAR (found in modern iPhones) along with a depth estimation foundation model, this method shows that you can prompt the system to reconstruct an extremely high fidelity point cloud better than either method alone and on par with extremely expensive LiDAR setups alone, such as those found on self driving cars.

MODERNBERT

BERT is an encoder only style model that is one of the most heavily used language models on the market, used in Google search for essentially every query. This new model from Answer AI, LightOn, and friends is faster, modern, and extremely performant. It can be used as a drop in replacement. They use a number of modern tricks like batch ramp to improve overall model performance.

AI IS BOOMING ON THE APP STORE, AND DEVELOPERS ARE TAKING ADVANTAGE OF IT

AI apps are flooding the App Store charts, but many prioritize cash grabs over quality, often misleading users with paywalls and subpar features. HUBX, dominating with apps like DaVinci AI, faces criticism for poor functionality and misleading marketing despite high rankings. Amidst the saturation, quality apps like Photoroom and Picsart AI stand out by delivering on their promises with effective AI tools.
