This Startup Is All In on Recursive Self-Improvement. Recursive makes the case that the benefits of using AI to build AI outweigh the risks. For the past few days I've been testing an impressive open-weight AI coding model called Flint. It suggests that fully recursive self-improvement, or RSI--an exciting and controversial approach that uses AI to build AI--is getting closer. Flint is the first offering from Recursive, a company that aims to use RSI to advance both AI itself and other areas of science using AI .

Let's start with a game. Open up your chatbot of choice--Claude, ChatGPT, Gemini--and type "Give me a random number between 1 and 10." You're going to get 7. Almost always. Now type "Another" and you'll get 3 or 4. Type "Another" again and you'll get 8 or 9. That won't work every time--but if it did for you, you may wonder if I have superpowers.

In both cases we observe that the predicted curve is reasonably close to the actual curve, more so at the beginning of the training (which is expected, sincethelinearapproximation ismorelikelytohold). Point-wise similarity of predicted and observed loss curve. Up to now we focused on prediction error rates (see e.g. We started defining training time as the first time the (smoothed) loss is belowagiventhreshold(whichwethennormalizedw.r.t. In Section 4we suggest that, in the case of MSE loss, itispossible to predict the training time on alargedataset using asubset ofthesamples. However,sinceourtraining time definition measures the time to reach the asymptotic value (which is what is most useful in practice) rather than the time reach an absolute threshold, this does not affect the accuracy of the prediction(seeAppendixC).

Scientific simulations and experimental measurements produce vast amounts of spatio-temporal data, yet extracting meaningful insights remains challenging due to high dimensionality, complex structures, and missing information. Traditional analysis methods often struggle with these issues, motivating the need for more robust, data-driven approaches. This dissertation explores deep learning methodologies to improve the analysis and visualization of spatio-temporal scientific ensembles, focusing on dimensionality reduction, flow estimation, and temporal interpolation. First, we address high-dimensional data representation through autoencoder-based dimensionality reduction for scientific ensembles. We evaluate the stability of projection metrics under partial labeling and introduce a Pareto-efficient selection strategy to identify optimal autoencoder variants, ensuring expressive and reliable low-dimensional embeddings. Next, we present FLINT, a deep learning model for high-quality flow estimation and temporal interpolation in both flow-supervised and flow-unsupervised settings. FLINT reconstructs missing velocity fields and generates high-fidelity temporal interpolants for scalar fields across 2D+time and 3D+time ensembles without domain-specific assumptions or extensive finetuning. To further improve adaptability and generalization, we introduce HyperFLINT, a hypernetwork-based approach that conditions on simulation parameters to estimate flow fields and interpolate scalar data. This parameter-aware adaptation yields more accurate reconstructions across diverse scientific domains, even with sparse or incomplete data. Overall, this dissertation advances deep learning techniques for scientific visualization, providing scalable, adaptable, and high-quality solutions for interpreting complex spatio-temporal ensembles.

This is achieved by a dedicated architecture and well chosen regularization penalties. We seek for a small-size dictionary of high level attribute functions that take as inputs the outputs of selected hidden layers and whose outputs feed a linear classifier. We impose strong conciseness on the activation of attributes with an entropy-based criterion while enforcing fidelity to both inputs and outputs of the predictive model. A detailed pipeline to visualize the learnt features is also developed.

The Flint water crisis has resulted in all-time high numbers of children with special needs and poor performance in school. More than 12,000 children to were exposed to toxic levels of lead in 2014 when the city switched it's public water source to the Flint River, where the water is considerably more acidic. This led to corrosion in lead pipes, which imbued the city's tap water with lead, and then introduced it into the drinking supply. Lead exposure has been linked to behavioral and cognitive problems, mental illness, and an underdeveloped brain. Now, researchers from Michigan and New Jersey experts have reported the rate of young children diagnosed with special needs increased by eight percent after 2014 while performance in math class dropped.

Cross-device federated learning (FL) has been well-studied from algorithmic, system scalability, and training speed perspectives. Nonetheless, moving from centralized training to cross-device FL for millions or billions of devices presents many risks, including performance loss, developer inertia, poor user experience, and unexpected application failures. In addition, the corresponding infrastructure, development costs, and return on investment are difficult to estimate. In this paper, we present a device-cloud collaborative FL platform that integrates with an existing machine learning platform, providing tools to measure real-world constraints, assess infrastructure capabilities, evaluate model training performance, and estimate system resource requirements to responsibly bring FL into production. We also present a decision workflow that leverages the FL-integrated platform to comprehensively evaluate the trade-offs of cross-device FL and share our empirical evaluations of business-critical machine learning applications that impact hundreds of millions of users.
