TLDR AI 2024-06-10

Odds are, you've received a suspicious phone call, text, or email asking for money. The scam might have been easy to spot — but with deepfakes and genAI, things are getting much weirder.

Sophisticated scams start with bad actors laying hands on your personal data. Often, they purchase this data legally from data brokers who profit from selling your phone number, DOB, SSN, and more.

Incogni scrubs your personal data from the web, confronting the 180+ data brokers on your behalf. And unlike other services, Incogni helps remove your sensitive information from ALL broker types, including people search sites.

Claude is more than just a middle-of-the-road, sycophantic AI that agrees with the user. Claude's personality and character have been specifically designed using a character variant of Constitutional AI. This post goes in-depth on how post-training is used to steer the type of output often generated by Claude to represent this desired character.

Apple is set to introduce its AI initiatives under the brand name "Apple Intelligence" in iOS 18 and other operating systems, focusing on daily life enhancements rather than creative tasks. Features will include AI-generated notification summaries, rich auto-replies in Messages and Mail, intelligent email categorization, an emoji creator, AI-powered photo editing, and transcriptions in Voice Memos.

Databricks has acquired Tabular, uniting key contributors to Apache Iceberg and Delta Lake to focus on data format compatibility for its lakehouse architecture. The goal is to achieve a single open standard for data interoperability to prevent data silos, starting with Delta Lake UniForm's compatibility solution.

Researchers have upgraded the popular YOLO object detectors with YOLO-World, introducing open-vocabulary detection. This approach combines vision-language modeling and large-scale dataset training, allowing it to identify a vast array of objects quickly and accurately, even in scenarios it wasn't specifically trained for.

Researchers have developed a Synthetic-Domain Alignment (SDA) framework to enhance test-time adaptation (TTA) methods. SDA effectively aligns source and synthetic domains by fine-tuning pretrained models with synthetic data generated through a conditional diffusion model.

Reward-based Noise Optimization (ReNO) is a new approach to enhance Text-to-Image (T2I) models during inference that optimizes the initial noise using signals from human preference reward models.

Inspectus is a versatile visualization tool for large language models that offers diverse insights into language model behaviors.

GPT-2 style transformer model contained entirely in a spreadsheet that includes all weights, parameters, and connections. It is a small model based on NanoGPT that is entirely contained in the rows and columns of a spreadsheet.

Researchers have created a new privacy-friendly method for camera localization using unique scene landmarks. This approach, which uses a CNN-based heatmap and 3D scene landmarks, is both storage-efficient and highly accurate, all without relying on actual 3D point clouds for localization.

Large language models (LLMs) like ChatGPT are not databases and can produce imprecise answers to questions, but they excel at generating responses that appear correct. The future of AI involves integrating LLMs into specialized tools or embedding them into existing applications, enhancing functionality while mitigating errors and improving user experience by contextualizing AI outputs within specific, manageable domains.

New dataset with 700k+ images and 2m+ annotations for computer vision 6D motion estimation (e.g., positions and rotations).

This model uses a number of computer vision techniques to reason about absolute and relative sizes of objects in monocular images.

OpenAI's CEO clarified that the voice of 'Sky' in ChatGPT isn't Scarlett Johansson's and has paused its use after a miscommunication.

Microsoft launched Copilot, powered by GPT, on Telegram.

Daniel Kokotajlo joined OpenAI with the hope that it would invest much more in safety research, but the company never made that pivot.
