Title: Efficient Neural Architecture Search for ensemble learning
Speaker: Aleksandr Chebykin
Abstract: Neural Architecture Search is the problem of learning a task-specific neural network structure from data. During the search, many candidate architectures need to be considered, but it is computationally infeasible to independently train them all. Weight sharing makes the search more efficient but also reduces the space of possible architectures. The tradeoffs of differently restricted search spaces are not obvious. Our idea is to traverse several spaces simultaneously in order to efficiently find an ensemble that is both small and well-performing.
Title: Bidirectional String Anchors: A New String Sampling Mechanism
Speaker: Solon Pissis
Abstract: In a previous LSH seminar, we presented bidirectional string anchors, a new mechanism for sampling strings, which has small density and is computable in linear time. Furthermore, we showed that by using this sampling, we can efficiently construct a small sketch that answers pattern matching queries in near-optimal time. In this seminar, we will present an experimental evaluation, which highlights the applicability of our sketch.
