Bisect and Conquer: Hierarchical Clustering via Max-Uncut Bisection
Sara Ahmadian, Vaggos Chatziafratis, Alessandro Epasto +4
Hierarchical Clustering is an unsupervised data analysis method which has been widely used for decades. Despite its popularity, it had an underdeveloped analytical foundation and t…
Depth-Width Trade-offs for ReLU Networks via Sharkovsky's Theorem
Vaggos Chatziafratis, Sai Ganesh Nagarajan, Ioannis Panageas +1
Understanding the representational power of Deep Neural Networks (DNNs) and how their structural properties (e.g., depth, width, type of activation unit) affect the functions they…
Adversarially Robust Low Dimensional Representations
Pranjal Awasthi, Vaggos Chatziafratis, Xue Chen +1
Many machine learning systems are vulnerable to small perturbations made to inputs either at test time or at training time. This has received much recent interest on the empirical…
