Webinar Replay – Space Loves AI: How AI promises to transform space operations

stp2y0 CommentsChat-GPT

For satellite operators, AI’s potential benefits are impossible to ignore. As Earth observation and communications constellations expand, AI tools promise to streamline operations, reduce on-orbit collisions and speed up analysis of remote sensing data. Opportunities and challenges for space-based AI with experts from the Aerospace Corporation, Stanford University’s Center for AEroSpace Autonomy Research (CAESAR), Magnestar, and Redwire Space were discussed. Panelists Mike Nemerouf, DirectorInnovation, Science and Technology Aerospace Corporation Al Tadros, CTORedwire Space Simone D’Amico, Co-founderStanford Center for AEroSpace Autonomy Research Moderator Debra WernerSenior Staff WriterSpaceNews Sponsored By Whether your mission requires persistent, high-resolution imagery or resilient communications, Redwire’s highly…

Building MLOps Capabilities at GitLab As a One-Person ML Platform Team

stp2y0 CommentsGenAI

Eduardo Bonet is an incubation engineer at GitLab, building out their MLOps capabilities. One of the first features Eduardo implemented in this role was a diff for Jupyter Notebooks, bringing code reviews into the data science process. Eduardo believes in an iterative, feedback-driven product development process, although he emphasizes that “minimum viable change” does not necessarily mean that there is an immediately visible value-add from the user’s point of view. While LLMs are quickly gaining traction, Eduardo thinks they’ll not replace ML or traditional software engineering but add to the capabilities. Thus, he believes that GitLab’s current focus on MLOps…

Generative AI Translation Startup DeepL Locks Up $300M

stp2y0 CommentsRAG models

Investors can’t get enough of different ways to use generative AI. Translation and language startup DeepL became the latest startup using generative AI to raise big, nabbing $300 million at a $2 billion post-money valuation in a round led by Index Ventures. The valuation is about double its previous $1 billion-plus valuation from January 2023. The round included participation from ICONIQ Growth, Teachers’ Venture Growth, IVP, Atomico and WiL (World Innovation Lab). The German startup language AI platform offers writing, editing and translation services for 63 markets and 32 languages for business use cases. The company said it has already…

Announcing General Availability of Liquid Clustering

stp2y0 CommentsViral Newsdata management, delta lake, liquid clustering

We’re excited to announce the General Availability of Delta Lake Liquid Clustering in the Databricks Data Intelligence Platform. Liquid Clustering is an innovative data management technique that replaces table partitioning and ZORDER so you no longer have to fine-tune your data layout to achieve optimal query performance. Liquid clustering significantly simplifies data layout-related decisions and provides the flexibility to redefine clustering keys without data rewrites. It allows data layout to evolve alongside analytic needs over time – something you could never do with partitioning on Delta. Since the Public Preview of Liquid Clustering at the Data and AI Summit last year, we’ve…

Ghostbuster: Detecting Text Ghostwritten by Large Language Models

stp2y0 CommentsAIlarge language models, text generation

The structure of Ghostbuster, our new state-of-the-art method for detecting AI-generated text. Large language models like ChatGPT write impressively well—so well, in fact, that they’ve become a problem. Students have begun using these models to ghostwrite assignments, leading some schools to ban ChatGPT. In addition, these models are also prone to producing text with factual errors, so wary readers may want to know if generative AI tools have been used to ghostwrite news articles or other sources before trusting them. What can teachers and consumers do? Existing tools to detect AI-generated text sometimes do poorly on data that differs from…

OpenAI and Wall Street Journal owner News Corp sign content deal

stp2y0 CommentsChat-GPT

ChatGPT developer OpenAI has signed a deal to bring news content from the Wall Street Journal, New York Post, the Times and the Sunday Times to the artificial intelligence platform, the companies said on Wednesday. Neither party disclosed a dollar figure for the deal.The deal will give OpenAI access to current and archived content from all of News Corp’s publications. The deal comes weeks after the AI heavyweight signed a deal with the Financial Times to license its content for the development of AI models. Earlier this year, OpenAI inked a similar contract with Axel Springer, parent of Business Insider…

Documenting your PhD — Keeping Track of Meetings, Experiments and Decisions • David Stutz

stp2y0 CommentsGenAI

A PhD can be a difficult endeavour. While becoming an expert in tackling a specific problems, it is easy to lose track of things: Have I read this paper before? What was the paper saying? Why did we decide to change course? Why am I running these experiments? Who did I talk to at the last conference? Throughout my PhD, I learned that documenting these things made me significantly more effective with minimal overhead. In this article, I want to share some learnings around what and how to keep track of PhD work. Introduction In the beginning of my PhD,…

Top Data Validation Tools for Machine Learning in 2024

stp2y0 CommentsViral News

Image generated with MidjourneyIt was challenging to stop myself from starting this article with some variation of the popular phrase "garbage in, garbage out." Well, I did it anyway. But jokes aside, we can easily imagine a situation in which we have built and deployed a machine learning model (possibly a black box) that accepts some input and returns some predictions. So far, so good.However, with tons of complexity happening before the model (data preprocessing and manipulation), the model itself, and any post-processing of the outputs, many things can go wrong. And in some mission-critical fields (finance, healthcare, or security),…
