Training-Time Attacks against k-Nearest Neighbors

no code implementations15 Aug 2022 Ara Vartanian, Will Rosenbaum, Scott Alfeld

We distill this goal to the task of performing a training-set data insertion attack against $k$-Nearest Neighbor classification ($k$NN).

Preference-Based Batch and Sequential Teaching

no code implementations17 Oct 2020 Farnam Mansouri, Yuxin Chen, Ara Vartanian, Xiaojin Zhu, Adish Singla

We analyze several properties of the teaching complexity parameter $TD(\sigma)$ associated with different families of the preference functions, e. g., comparison to the VC dimension of the hypothesis class and additivity/sub-additivity of $TD(\sigma)$ over disjoint domains.

Preference-Based Batch and Sequential Teaching: Towards a Unified View of Models

no code implementations NeurIPS 2019 Farnam Mansouri, Yuxin Chen, Ara Vartanian, Xiaojin Zhu, Adish Singla

In our framework, each function $\sigma \in \Sigma$ induces a teacher-learner pair with teaching complexity as $\TD(\sigma)$.
