Crowd counting problem aims to count the number of objects within an image or a frame in the videos and is usually solved by estimating the density map generated from the object location annotations. The values in the density map, by nature, take two possible states: zero indicating no object around, a non-zero value i…

New lens on self-supervised learning: parameter identifiability.

problem Identifying good features for downstream tasks in self-supervised learning.
method Consider data from a parametric probabilistic model, train a predictor, and ask if ground truth parameters can be read off the optimal predictor.
result Some prediction tasks yield identifiability, others do not, revealing a rich landscape.

Most machine translation systems generate text autoregressively from left to right. We, instead, use a masked language modeling objective to train a model to predict any subset of the target words, conditioned on both the input text and a partially masked target translation. This approach allows for efficient iterative…

Develops a multilevel Monte Carlo framework with dropout for efficient uncertainty quantification.

problem Efficiently quantify uncertainty in complex models using dropout.
method Integrates multilevel Monte Carlo with Monte Carlo dropout, creating coupled estimators to reduce variance.
result Demonstrates significant variance reduction and efficiency gains over single-level Monte Carlo dropout.
