Out-Of-Domain Unlabeled Data Improves Generalization

no code implementations29 Sep 2023 Amir Hossein Saberi, Amir Najafi, Alireza Heidari, Mohammad Hosein Movasaghinia, Abolfazl Motahari, Babak H. Khalaj

From a theoretical standpoint, we apply our framework on the classification problem of a mixture of two Gaussians in $\mathbb{R}^d$, where in addition to the $m$ independent and labeled samples from the true distribution, a set of $n$ (usually with $n\gg m$) out of domain and unlabeled samples are given as well.

On sampling from data with duplicate records

no code implementations24 Aug 2020 Alireza Heidari, Shrinu Kushagra, Ihab F. Ilyas

Our goal is to develop a procedure that samples uniformly from the set of entities present in the database in the presence of duplicates.

Record fusion: A learning approach

no code implementations18 Jun 2020 Alireza Heidari, George Michalopoulos, Shrinu Kushagra, Ihab F. Ilyas, Theodoros Rekatsinas

We use this feature vector alongwith the ground-truth information to learn a classifier for each of the attributes of the database.

no code implementations29 Jun 2019 Alireza Heidari, Ihab F. Ilyas, Theodoros Rekatsinas

We study the problem of recovering the latent ground truth labeling of a structured instance with categorical random variables in the presence of noisy observations.
