Looking for better ways to code with Cursor and came across this banger.
Anyone else have workflows that work for them?

Introducing open-Deep-Research by @huggingface ! 💥
Deep Research from @OpenAI is really good... But it's closed, as usual.
> So with a team of cracked colleagues, we set ourselves a 24hours deadline to replicate and open-source Deep Research!
➡️ We built open-Deep-Research, an entirely open agent that can: navigate the web autonomously, scroll and search through pages, download and manipulate files, run calculation on data...
We aimed for the best performance: are the agent's answers really rigorous?
On GAIA benchmark, Deep Research had 67% accuracy on the validation set.
➡️ open Deep Research is at 55% (powered by o1), but it is:
- the best pass@1 solution submitted
- the best open solution
And it's only getting started ! Please jump in, drop PRs, and let's bring it to the top 🚀

You are the world’s best software engineer, comedic roaster, and mentor. For the code I provide:
1. **Roast** it mercilessly with humor and sarcasm.
2. **Educate** on precisely what’s wrong: discuss the architecture, design patterns, naming, structure, testing pitfalls, etc.
3. **Refactor** the code to perfection:
- Use best practices and current frameworks/libraries
- Maintain a consistent coding style and naming conventions
- Add in TSDoc or relevant docstrings for clarity
4. **Deliver** a final, fully working code sample:
- **No placeholders or pseudo-code**
- Complete file(s) with all relevant code
5. **Explain** how these changes benefit future expansions, especially for AI-based code refactoring or generation.

I’m excited to share our recent paper published in @TheAJNR on glioblastoma and tumefactive demyelinating lesions of the brain, with multiple validation steps.
A special thanks to my co-authors and @NIH for their support on this project!

Feel the need to point out again — even slightly more sophisticated sampling can overcome mode collapse in synthetic data.

🚨 "AI models collapse when trained on recursively generated data" was among the most influential AI papers of 2024 - don't miss it! Bookmark & download it below. Interesting quotes:
"The development of LLMs is very involved and requires large quantities of training data. Yet, although current LLMs2,4–6, including GPT-3, were trained on predominantly human-generated text, this may change. If the training data of most future models are also scraped from the web, then they will inevitably train on data produced by their predecessors. In this paper, we investigate what happens when text produced by, for example, a version of GPT forms most of the training dataset of following models. What happens to GPT generations GPT-{n} as n increases? We discover that indiscriminately learning from data produced by other models causes ‘model collapse’—a degenerative process whereby, over time, models forget the true underlying data distribution, even in the absence of a shift in the distribution over time"
-
"Our evaluation suggests a ‘first mover advantage’ when it comes to training models such as LLMs. In our work, we demonstrate that training on samples from another generative model can induce a distribution shift, which—over time—causes model collapse. This in turn causes the model to misperceive the underlying learning task. To sustain learning over a long period of time, we need to make sure that access to the original data source is preserved and that further data not generated by LLMs remain available over time. The need to distinguish data generated by LLMs from other data raises questions about the provenance of content that is crawled from the Internet: it is unclear how content generated by LLMs can be tracked at scale.

Contrarians love to ask: “But what did people do before [insert public health measure]??”
And the answer is always just: “They died, or they buried everyone they loved.”

I've been thinking about in-context learning for nearly 3 years. While there is still plenty I don't fully understand, five papers have--to a very large extent--shaped my perspective on it, and I believe everyone should read them.
1. "What Can Transformers Learn In-Context? A Case Study of Simple Function Classes", by my now MSR colleague Shivam Garg (@shivamg_13) and Dimitris Tsipras (@tsiprasd ) et al.
2. "What learning algorithm is in-context learning? Investigations with linear models" by Ekin Akyürek (@akyurekekin) et al.
3. "Transformers learn in-context by gradient descent" by my friend Johannes von Oswald (@oswaldjoh) et al
4. "MetaICL: Learning to Learn In Context" by Sewon Min (@sewon__min) et al.
5. "Rethinking the Role of Demonstrations: What Makes In-Context Learning Work?" again by Sewon Min et al.

The true generative model is Nature -- a collection of causal mechanisms. Under what conditions can a trained model with partial observability exhibit patterns similar to those found in Nature?
We explored this question with Bengio, Xia, and Lee in a NeurIPS-21 paper: causalai.net/r80.pdf. Specifically, we developed the concept of causal inductive biases and examined what makes a neural or any other learned model 'generative.'
The key insight to answering this question comes from the constraints imposed on the underlying distributions and graphical models studied within the Pearl Causal Hierarchy framework, as introduced in causalai.net/r60.pdf.
(The implications of such discussion resolved some long-standing confusion in the literature, which conflates the concepts of generative and causal-- where the latter implies the former but not vice versa.)
The newly developed machinery can help us tackle many modern ML tasks, including counterfactual inferences (causalai.net/r87.pdf), causal abstractions (causalai.net/r101.pdf), counterfactual image editing (causalai.net/r103.pdf), and fair ML (causalai.net/r90.pdf).

Medically adapted foundation models (think Med-*) turn out to be more hot air than hot stuff. Correcting for fatal flaws in evaluation, the current crop are no better on balance than generic foundation models, even on the very tasks for which benefits are claimed.
🧵 Are "medical" LLMs/VLMs *adapted* from general-domain models, always better at answering medical questions than the original models?
In our oral presentation at #EMNLP2024 today (2:30pm in Tuttle), we'll show that surprisingly, the answer is "no".

The Treasure Trove Hidden in Plain Sight: The Utility of GPT-4 in Chest Radiograph Evaluation | Radiology
This study evaluates the potential of OpenAI’s GPT-4 with Advanced Data Analysis (ADA) to help radiologists analyze large medical datasets. The researchers tested GPT-4’s ability to perform basic and advanced statistical analyses, visualize data, and build machine learning models using a real-world dataset of chest radiographs. The study found that GPT-4 performed well in these tasks, often producing results comparable to those of human experts. However, the researchers also highlight the importance of careful statistical oversight and external validation, as GPT-4 sometimes made errors or introduced inconsistencies. The authors conclude that GPT-4 shows promise for facilitating complex data analysis in radiology, but it should be used as a tool to supplement, not replace, human expertise.
