Feature learning strength (FLS), i.e., the inverse of the effective output scaling of a model, plays a critical role in shaping the optimization dynamics of neural nets. While its impact has been extensively studied under the asymptotic regimes — both in training time and FLS — existing theory offers limited insight into how FLS affects generalization in practical settings, such as when training is stopped upon reaching a target training risk. In this work, we investigate the impact […]

The Rust Security Response WG was notified that the Rust standard library did not properly escape arguments when invoking batch files (with the bat and cmd extensions) on Windows using the Command API. An attacker able to control the arguments passed to the spawned process could execute arbitrary shell commands by bypassing the escaping. The severity of this vulnerability is critical if you are invoking batch files on Windows with untrusted arguments. No other platform or use is […]

“Speed” in data engineering is a trade-off, not a single metric. To build effective systems, you must distinguish between two competing concepts: – Data Latency (Freshness): How long it takes for an event to reach your report. – Query Latency (Responsiveness): How long a user waits for a dashboard to load. The Conflict: Optimizing for real-time freshness often slows down query performance because the system can’t pre-calculate data. Conversely, pre-calculating data for “snappy” dashboards usually requires batching, which […]

Decentralized Federated Learning (DFL) enables clients with local data to collaborate in a peer-to-peer manner to train a generalized model. In this paper, we unify two branches of work that have separately solved important challenges in DFL: (i) gradient tracking techniques for mitigating data heterogeneity and (ii) accounting for diverse availability of resources across clients. We propose $textit{Sporadic Gradient Tracking}$ ($texttt{Spod-GT}$), the first DFL algorithm that incorporates these factors over general directed graphs by allowing (i) client-specific gradient […]

This is the first dev snapshot for 4.4! During the beta and release candidate stages of 4.3, we accumulated a lot of PRs that were of great quality, but deemed too risky to include in 4.3. We have begun merging those PRs now and have quickly gathered a lot of changes that warrant a dev release! Many of the changes in this release are bug fixes that will be backported to Godot 4.3 and released in 4.3.1! So […]
