The announcement of new tariffs by President Donald Trump on April 9, 2025, sent shockwaves across various financial markets, including cryptocurrencies. However, Coldware (COLD) has emerged as a fighter, defying market sentiment and continuing to rise despite the broader downturn in the market.

F1@K is a metric used to evaluate the factual accuracy of model responses, focusing on precision and recall of supported facts. The choice of K, the number of facts needed for full recall, influences how responses are rated, with higher K values encouraging models to pack responses with supported facts. The metric accounts for precision-recall trade-offs, showing that shorter responses tend to have higher...

SAFE (Search-Augmented Fact Evaluation) uses a language model to assess the factual accuracy of long-form responses. It splits responses into individual facts, revises them for clarity, and verifies their accuracy using Google Search. The process involves multiple steps like determining relevance, issuing search queries, and rating facts as supported or not. Challenges include bias from the language model and varying generalization across topics, which...

Amazon's Nova Act is an AI agent that actually acts. Nova Act has a 94% success rate interacting with finicky calendar widgets. The toolkit is Amazon’s first public step toward artificial general intelligence.

Explore the evolving world of Web3 gaming, where blockchain promises player ownership, token stability, and decentralized game development.

LongFact is a large-scale factuality benchmark created through a dynamic process involving GPT-4, focusing on diverse topics across various domains. Topics were carefully chosen to ensure comprehensive coverage of factuality. The set includes both LongFact-Concepts (niche concepts) and LongFact-Objects (specific entities). Example prompts from these categories are provided, and the full dataset is available on GitHub.

This FAQ section addresses common queries related to the reproducibility of results, the SAFE evaluation system, common causes of errors in AI and human annotations, and the impact of recall and postambles on model performance. It also discusses the exclusion of LongFact-Concepts from benchmarking and how these findings can be applied to other domains.

Google A2A - a first look at another agent-agent protocol and compared to Anthropic’s MCP. Well, they are very similar.

The study was conducted using fMRI-to-Image Reconstruction. The results were published in the journal Human Experiments. The study was published on November 13, 2013.

This appendix provides detailed materials on experimental conditions, quality control measures, prompts used for generating supplementary context, and sample outputs from GPT-4.

This paper introduces SAFE, an automatic evaluation method for long-form factuality, outperforming human annotators and offering cheaper, scalable solutions for model evaluation. Future research will focus on improving LLM factuality through pretraining and external tools.

TL;DR We tested GPS, RFID, BLE trackers, and AirTags for real-world business asset tracking. GPS works for powered vehicles but fails on mobile, unpowered gear due to battery and SIM issues. RFID is viable indoors but needs infrastructure — not usable in open environments. BLE trackers like Tile and Milwaukee One-Key barely function unless someone nearby is running the app. AirTags, when paired with...

Optimizing dialogue context size and type improves label consistency, with heuristics showing great promise for increasing productivity. Future studies will explore open-source LLMs for transparency.

Empathy maps and user personas are popular visualization tools helping product teams synthesize user research insights. However, they come with their shortcomings and, instead of clarity, they can bring confusion and lead to overconfident, misleading product decisions.
