Salesforce AI Research Introduces WALT (Web Agents that Learn Tools): Enabling LLM agents to Automatically Discover Reusable Tools from Any Website

A team of Salesforce AI researchers introduced WALT (Web Agents that Learn Tools), a framework that reverse-engineers latent website functionality into reusable invocable tools. It reframes browser automation around callable tools rather than long chains of clicks. Agents then call operations such as search, filter, sort, post_comment, and create_listing. This reduces dependence on large language…

Pandas: Advanced GroupBy Techniques for Complex Aggregations

Image by Author   #  Introduction   While groupby().sum() and groupby().mean() are fine for quick checks, production-level metrics require more robust solutions. Real-world tables often involve multiple keys, time-series data, weights, and various conditions like promotions, returns, or outliers. This means you frequently need to compute totals and rates, rank items within each segment, roll…

Apple Released FastVLM: A Novel Hybrid Vision Encoder which is 85x Faster and 3.4x Smaller than Comparable Sized Vision Language Models (VLMs)

Introduction Vision Language Models (VLMs) allow both text inputs and visual understanding. However, image resolution is crucial for VLM performance for processing text and chart-rich data. Increasing image resolution creates significant challenges. First, pretrained vision encoders often struggle with high-resolution images due to inefficient pretraining requirements. Running inference on high-resolution images increases computational costs and…
