Forexample, age estimation aims toestimate the age ofagivenface image while image aesthetic assessment predicts the aesthetic score for an image.

Those topological compositions are empirically effective and observed to smooth the loss landscape and facilitate the gradient flow in general.

What distinguishes ourweighting scheme from existing boosting methods isthatwhile the output ofeach weak estimator isamultivariate probability distribution, the data only provides the specific event that occurred and the time of occurrence and thus we introduce new notions of "predictioncorrectness"thatapplyinoursetting.

Classic UOD methods discover outliers by examining the basic characteristics of data, such as statistical properties [32], cluster membership [33,34],density[35,36,37],proximity[38,39],etc.

In this paper, we study the problem of quantifying knowledge contained in an LLM regarding a given set of facts.

Estimating a vector x from noisy linear measurements Ax + w often requires use of prior knowledge or structural constraints on x for accurate reconstruction. Several recent works have considered combining linear least-squares estimation with a generic or "plug-in" denoiser function that can be designed in a modular manner based on the prior knowledge about x.

We further show that optimistic posterior sampling can control this Hellinger distance, when we measure model error via data likelihood. This technique allows us to design and analyze unified posterior sampling algorithms with state-of-the-art sample complexity guarantees for many model-based RL settings.
