Teaching Wav2Vec2 the Language of the Brain

Tobias Fiedler, Leon Hermann, Florian Müller +4

The decoding of continuously spoken speech from neuronal activity has the potential to become an important clinical solution for paralyzed patients. Deep Learning Brain Computer In…

Efficient Fault-Tolerant Search by Fast Indexing of Subnetworks

Davide Bilò, Keerti Choudhary, Sarel Cohen +2

We design sensitivity oracles for error-prone networks. For a network problem , the data structure preprocesses a network and sensitivity parameter such that, for…

Improved Distance (Sensitivity) Oracles with Subquadratic Space

Davide Bilò, Shiri Chechik, Keerti Choudhary +3

A distance oracle (DO) with stretch for a graph is a data structure that, when queried with vertices and , returns a value such that $d(s,t)…

A New Approach for Approximating Directed Rooted Networks

Sarel Cohen, Lior Kamma, Aikaterini Niklanovits

We consider the k-outconnected directed Steiner tree problem (k-DST). Given a directed edge-weighted graph , where , and an integer , the goal i…

Robust Parameter Fitting to Realistic Network Models via Iterative Stochastic Approximation

Thomas Bläsius, Sarel Cohen, Philipp Fischbeck +2

Random graph models are widely used to understand network properties and graph algorithms. Key to such analyses are the different parameters of each model, which affect various net…

Improved Approximate Distance Oracles: Bypassing the Thorup-Zwick Bound in Dense Graphs

Davide Bilò, Shiri Chechik, Keerti Choudhary +3

Despite extensive research on distance oracles, there are still large gaps between the best constructions for spanners and distance oracles. Notably, there exist sparse spanners wi…
