When marketing emails fail, they almost never fail loudly. The campaigns are queued. Dashboards look fine. Open rates dip a little, then a little more. Someone suggests testing a new subject line. Another person tweaks send time. What’s actually breaking isn’t copy or creative. It’s trust. And trust erodes quietly. I learned this running marketing technology and operations at Nextdoor, where we send hundreds of millions of emails a year to neighbors and businesses around the world. Some […]

arXiv:2603.16798v1 Announce Type: cross Abstract: We study mean estimation for a Gaussian distribution with identity covariance in $mathbb{R}^d$ under a missing data scheme termed realizable $epsilon$-contamination model. In this model an adversary can choose a function $r(x)$ between 0 and $epsilon$ and each sample $x$ goes missing with probability $r(x)$. Recent work Ma et al., 2024 proposed this model as an intermediate-strength setting between Missing Completely At Random (MCAR) — where missingness is independent of the data — […]

arXiv:2601.09841v1 Announce Type: new Abstract: When training machine learning (ML) models for potential deployment in a healthcare setting, it is essential to ensure that they do not replicate or exacerbate existing healthcare biases. Although many definitions of fairness exist, we focus on path-specific causal fairness, which allows us to better consider the social and medical contexts in which biases occur (e.g., direct discrimination by a clinician or model versus bias due to differential access to the healthcare system) […]

arXiv:2602.03918v1 Announce Type: new Abstract: Masked self-supervised vision transformers have become a dominant pretraining paradigm, yet their substantial model size poses significant challenges for resource-constrained deployment and efficient transfer learning. A fundamental question remains: are all transformer blocks equally important for downstream performance? In this paper, we show that block importance in masked self-supervised vision transformers can be accurately estimated without access to any data. Our key finding is that the information entropy of pretrained block weights strongly […]

Hi! I am trying to explore and learn some RL algorithms and implement them in Gym’s Car Racing environment ( https://gymnasium.farama.org/environments/box2d/car_racing/ ). Instead of using the image on the screen for my state, I measure the distance from the car to the edge of the track at 5 points (90º left, 45º left, forwards, 45º right, 90º right), along with the car’s current speed, and pass that as my state. I also give a fixed -1 reward if […]
