The setting of ϵ requires some consideration, as it dictates the balance between exploration and exploitation. We might also make it time-dependent (e.g., something like ϵ_n=1/n), yielding a high exploration rate in the beginning which decreases with the number of measurements. Harmonic stepsizes allow more control over the time …

Machine learning describes an array of computational and nested statistical methods whereby a computer can 'learn' and subsequently make predictions or identify patterns in data. With the increasing volume and variety of numerical data in the geosciences, and widespread availability of the needed computing power, machine …

Abstract. Neural Machine Translation (NMT) has shown remarkable progress over the past few years, with production systems now being deployed to end-users. As the field is moving rapidly, it has become unclear which elements of NMT architectures have a significant impact on translation quality. In this work, we present a large-scale analysis of ...

Exploration and exploitation are two fundamental aspects of any machine learning strategy. They refer to the trade-off between trying new actions or policies that …
