Snowflake Looks to AI to Bolster Growth

stp2y0 CommentsViral News

(Michael Vi/Shutterstock) Investors in Snowflake breathed a sigh of relief this week when the cloud data warehouser reported solid revenue growth for its first quarter and raised its guidance for the rest of the year. But questions still remain over its long-term growth, which the company is hoping that artificial intelligence will power. The company’s acquisition this week of assets of TruEra fits that mold. Snowflake on Wednesday reported $829 million in total GAAP revenues for the quarter ended April 30, 2024, representing a 33% increase over the same period last year. It reported 14 cents per share, which was…

Practical Tips for Finetuning LLMs Using LoRA (Low-Rank Adaptation)

stp2y0 CommentsAI

Low-rank adaptation (LoRA) is among the most widely used and effective techniques for efficiently training custom LLMs. For those interested in open-source LLMs, it's an essential technique worth familiarizing oneself with.Last month, I shared an article with several LoRA experiments, based on the open-source Lit-GPT repository that I co-maintain with my colleagues at Lightning AI. This Ahead of AI article aims to discuss the primary lessons I derived from my experiments. Additionally, I'll address some of the frequently asked questions related to the topic. If you are interested in finetuning custom LLMs, I hope these insights will save you some…

Bringing generative artificial intelligence to space

stp2y0 CommentsChat-GPT

TAMPA, Fla. — Amazon Web Services is busy positioning its cloud infrastructure business to capitalize on the promise of generative artificial intelligence for transforming space and other industries. More than 60% of the company’s space and aerospace customers are already using some form of AI in their businesses, according to AWS director of aerospace and satellite Clint Crosier, up from single digits around three years ago. Crosier predicts similar growth over the next few years in space for generative AI, which uses deep-learning models to answer questions or create content based on patterns detected in massive datasets, marking a major…

The New Breed of Open Mixture-of-Experts (MoE) Models. In a push to beat the closed-box AI models from the AI Titans, many startups and research orgs have embarked in releasing open MoE-based models. These new breed of MoE-based models introduce many clever architectural tricks, and seek to balance training cost efficiency, output quality, inference performance and much more. For an excellent introduction to MoEs, checkout this long post by the Hugging Face team: Mixture of Experts ExplainedWe’re starting to see several open MoE-based models achieving near-SOTA or SOTA performance as compared to e.g. OpenAI GPT-4 and Google Gemini 1.5 Pro.…

German AI defence giant Helsing eyes $4B valuation in Series C funding

stp2y0 CommentsNews

German AI defense company Helsing is reportedly in talks to secure €370 million in Series C funding, potentially valuing the company at a staggering $4 billion. The round is said to be led by US VC giant General Catalyst, according to Forbes. In September last year, the company led Helsing in securing €209 million in Series B funding, solidifying its status as Europe's most well-funded defencetech startup and among the leading AI companies in the field. The Series C would bring its funds to almost €700 million. Founded in 2021, Helsing develops AI-based capabilities to "protect our democracies." The company has been active in…

Big tech has distracted world from existential risk of AI, says top scientist

stp2y0 CommentsChat-GPT

Big tech has succeeded in distracting the world from the existential risk to humanity that artificial intelligence still poses, a leading scientist and AI campaigner has warned.Speaking with the Guardian at the AI Summit in Seoul, South Korea, Max Tegmark said the shift in focus from the extinction of life to a broader conception of safety of artificial intelligence risked an unacceptable delay in imposing strict regulation on the creators of the most powerful programs.“In 1942, Enrico Fermi built the first ever reactor with a self-sustaining nuclear chain reaction under a Chicago football field,” Tegmark, who trained as a physicist,…

TMLR Paper “Conformal Prediction under Ambiguous Ground Truth” • David Stutz

stp2y0 CommentsGenAI

Conformal prediction uses a held-out, labeled set of examples to calibrate a classifier to yield confidence sets that include the true label with user-specified probability. But what happens if even experts disagree on the ground truth labels. Commonly, this is resolved by taking the majority voted label from multiple expert. However, in difficult and ambiguous tasks, the majority voted label might be misleading and a bad representation of the underlying true posterior distribution. In this paper, we introduce Monte Carlo conformal prediction which allows to perform conformal calibration directly against expert opinions or aggregate statistics thereof. Abstract Conformal Prediction (CP)…

Microsoft’s CTO on How to Build Enduring Businesses in the AI Era

stp2y0 CommentsRAG models

This week I flew out to Seattle to attend Microsoft's developer conference, Build. Read my full report and Evan Armstrong's analysis.Kevin Scott is not your average CTO. He says things like “chill” and “shit,” and he wears button-down shirts with funky patterns. Oh yeah, and he builds supercomputers. In his spare time, he likes to do woodworking.Scott was the first person at Microsoft to recognize the importance of AI and instigated its OpenAI partnership, which has become the single most important strategic move at Microsoft since the dot-com era. He's hopeful that in the next two to three years, a model…
