Proud to be part of this open-source initiative focused on AI-assisted research that puts scientific rigor at its core.

We just released it, try it out!

We will also be hiring people soon to join us and help us build this ecosystem. More info in the post below 👇

[Lightcone Research @LightconeR]

Today, we’re launching Lightcone Research.

AI is changing what’s tractable in scientific research, putting more ambitious questions within reach.

We build open-source infra that turn this expanded reach into results other scientists can reproduce, inspect, and build on.

Have you ever done a dense grid search over neural network hyperparameters? Like a *really dense* grid search? It looks like this (!!). Blueish colors correspond to hyperparameters for which training converges, redish colors to hyperparameters for which training diverges.

[Marc Huertas-Company @MHuertasCompany]

I am hiring a postdoc to work on JWST, Euclid and ML at the IAC in Spain. Please, get in touch if interested or let me know if you know someone who might be. Deadline Nov. 30. https://t.co/YXzRuQBTAd

Today I’m launching Open Interpreter, an open-source Code Interpreter that runs locally.

Summarize PDFs, visualize datasets, and control your browser — all from a ChatGPT-like interface in your terminal.

At @MistralAI we're releasing our very first model, the best 7B in town (outperforming Llama 13B on all metrics, and good at code), Apache 2.0.

We believe in open models and we'll push them to the frontier https://t.co/HjT5Xrvpxs

Very proud of the team !

[Wolf Vollprecht @wolfvollprecht]

Today we are launching pixi! It's our new package manager for the conda ecosystem by @prefix_dev. It comes with powerful lockfiles out of the box, cross-platform workflows and the speed of Rust.

[ESA's Euclid mission @ESA_Euclid]

🥁 They're here... the first test images from the #DarkUniverse 🕵️ detective give us a tantalising glimpse of what is yet to come from a fully calibrated mission later this autumn 🤩

No More GIL!
the Python team has officially accepted the proposal.

Congrats @colesbury on his multi-year brilliant effort to remove the GIL, and a heartfelt thanks to the Python Steering Council and Core team for a thoughtful plan to make this a reality.

Meta releases Llama 2: Open Foundation and Fine-Tuned Chat Models

paper: https://t.co/o9Ze0GyvUc
blog: https://t.co/BnLYECD5KS

develop and release Llama 2, a collection of pretrained and fine-tuned large language models (LLMs) ranging in scale from 7 billion to 70 billion parameters. Our fine-tuned LLMs, called Llama 2-Chat, are optimized for dialogue use cases. Our models outperform open-source chat models on most benchmarks we tested, and based on our human evaluations for helpfulness and safety, may be a suitable substitute for closedsource models. We provide a detailed description of our approach to fine-tuning and safety improvements of Llama 2-Chat in order to enable the community to build on our work and contribute to the responsible development of LLMs.

The Machine Learning and the Physical Sciences workshop will return for a 6th edition at #NeurIPS2023! More info coming soon! 📢🔭⚗️🧲

[Valeriy M., PhD, MBA, CQF @predict_addict]

The new edition of one of the most popular machine learning textbooks is coming in summer 2023 and unlike all the previous editions is in Python 🐍 and available for free as PDF book.

When it comes to machine learning Python is clearly taking over, for time series it already did couple of years ago, see my Medium article “Python vs R for time-series forecasting”

Le début d'une nouvel grande aventure en astronomie s'annonce demain: le lancement du satellite Euclid, qui va nous fournir un incroyable carte de l'Univers sur 10 milliards d'années pour notamment mieux comprendre la nature de l'énergie noire et de la matière noire.
