Training set cleansing of backdoor poisoning by self-supervised representation learning

H. Wang, S. Karami, O. Dia +6

A backdoor or Trojan attack is an important type of data poisoning attack against deep neural network (DNN) classifiers, wherein the training dataset is poisoned with a small numbe…

Active Learning for Non-Parametric Choice Models

Fransisca Susan, Negin Golrezaei, Ehsan Emamjomeh-Zadeh +1

We study the problem of actively learning a non-parametric choice model based on consumers' decisions. We present a negative result showing that such choice models may not be ident…

Adversarial Online Learning with Changing Action Sets: Efficient Algorithms with Approximate Regret Bounds

Ehsan Emamjomeh-Zadeh, Chen-Yu Wei, Haipeng Luo +1

We revisit the problem of online learning with sleeping experts/bandits: in each time step, only a subset of the actions are available for the algorithm to choose from (and learn a…

The Complexity of Interactively Learning a Stable Matching by Trial and Error

Ehsan Emamjomeh-Zadeh, Yannai A. Gonczarowski, David Kempe

In a stable matching setting, we consider a query model that allows for an interactive learning algorithm to make precisely one type of query: proposing a matching, the response to…

A General Framework for Robust Interactive Learning

Ehsan Emamjomeh-Zadeh, David Kempe

We propose a general framework for interactively learning models, such as (binary or non-binary) classifiers, orderings/rankings of items, or clusterings of data points. Our framew…

Adaptive Hierarchical Clustering Using Ordinal Queries

Ehsan Emamjomeh-Zadeh, David Kempe

In many applications of clustering (for example, ontologies or clusterings of animal or plant species), hierarchical clusterings are more descriptive than a flat clustering. A hier…

Mixture Selection, Mechanism Design, and Signaling

Yu Cheng, Ho Yee Cheung, Shaddin Dughmi +3

We pose and study a fundamental algorithmic problem which we term mixture selection, arising as a building block in a number of game-theoretic applications: Given a function fr…

Deterministic and Probabilistic Binary Search in Graphs

Ehsan Emamjomeh-Zadeh, David Kempe, Vikrant Singhal

We consider the following natural generalization of Binary Search: in a given undirected, positively weighted graph, one vertex is a target. The algorithm's task is to identify the…
