    Sammanfattning : In this thesis, the effects of incorporating unstructured data—images in the wild—in contextual multi-armed bandits are investigated, when used within a recommender system setting, which focuses on picture-based content suggestion. The idea is to employ image features, extracted by a pre-trained convolutional neural network, and study the resulting bandit behaviors when including respective excluding this information in the typical context creation, which normally relies on structured data sources—such as metadata.

    Sammanfattning : Features are an inherent unit of development of every software; and are defined as a set of implementation artifacts that constitute a functionality that adds value to the product, and is perceived useful by the customer. Locating features in source code is a typical software developer task, whether it before implementing a new feature, or maintaining and bug fixing of existing ones, as it is essential to know where to make changes.
