ImpressLearn: Continual Learning via Combined Task Impressions

no code implementations29 Sep 2021 Dhrupad Bhardwaj, Julia Kempe, Artem M Vysogorets, Angela Teng, Evaristus Ezekwem

Starting from existing work on network masking (Wortsman et al., 2020), we show that a simple to learn linear combination of a small number of task-specific masks (”impressions”) ona randomly initialized backbone network is sufficient to both retain accuracy on previously learned tasks, as well as achieve high accuracy on new tasks.

The NTK Adversary: An Approach to Adversarial Attacks without any Model Access

no code implementations29 Sep 2021 Nikolaos Tsilivis, Julia Kempe

In particular, in the regime where the Neural Tangent Kernel theory holds, we derive a simple, but powerful strategy for attacking models, which in contrast to prior work, does not require any access to the model under attack, or any trained replica of it for that matter.

Quantum Walks On Graphs

no code implementations18 Dec 2000 Dorit Aharonov, Andris Ambainis, Julia Kempe, Umesh Vazirani

We set the ground for a theory of quantum walks on graphs- the generalization of random walks on finite graphs to the quantum world.

Universal simulation of Markovian quantum dynamics

no code implementations15 Aug 2000 Dave Bacon, Andrew M. Childs, Isaac L. Chuang, Julia Kempe, Debbie W. Leung, Xinlan Zhou

Although the conditions for performing arbitrary unitary operations to simulate the dynamics of a closed quantum system are well understood, the same is not true of the more general class of quantum operations (also known as superoperators) corresponding to the dynamics of open quantum systems.
