1. 1. An Empirical Survey of Bandits in an Industrial Recommender System Setting

   Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

   Författare :Tobias Schwarz; Johan Brandby; [2023-09-21]

   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.

4. 3. Causal Reinforcement Learning for Bandits with Unobserved Confounders

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Mingwei Deng; [2023]
   Nyckelord :;

   Sammanfattning : Reinforcement Learning (RL) has been recognized as a valuable tool in various fields. However, its application is limited by its reliance on extensive data through a trial-and-error approach and challenges in generalizing learned policies. LÄS MER

   Sammanfattning : Vikings and pirates have been studied through the years in both the archaeological and historical disciplines. Both have been compared with each other, especially if Vikings can be classified as pirates or if they practiced piracy. LÄS MER

7. 5. Graph Bandits : Multi-Armed Bandits with Locality Constraints

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Kasper Johansson; [2022]
   Nyckelord :Multi-armed bandits; locality constraints; reinforcement learning; Flerarmade banditer; lokala restriktioner; förstärkningsinlärning;

   Sammanfattning : Multi-armed bandits (MABs) have been studied extensively in the literature and have applications in a wealth of domains, including recommendation systems, dynamic pricing, and investment management. On the one hand, the current MAB literature largely seems to focus on the setting where each arm is available to play at each time step, and ignores how agents move between the arms. LÄS MER
