1. 1. Risk-Averse Multi-Armed Bandit Problem with Multiple Plays

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

   Författare :Siri Dahlgren; Nicholas Marriott; [2023-10-23]
   Nyckelord :MAB; Gittins; Markovian bandit; risk-aversion; policy iteration; multiple plays;

   Sammanfattning : This study aims to construct an efficient heuristic, referred to as RA, for a riskaverse Markovian multi-armed bandit problem (MAB) with multiple plays. The RA incorporates risk-aversion and multiple plays by modifying the Gittins index strategy. LÄS MER

3. 2. 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]
   Nyckelord :computer science; industrial application; machine learning; reinforcement learning; multi-armed bandits; MAB; contextual multi-armed bandits; survey; batch learning;

   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. Implementation of an automatic tangential flow filtration system for latex immunoassay production

   Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

   Författare :Filippa Stolpe; Sofia Kullander; [2023]
   Nyckelord :biotechnology; bioprocess; diagnostics; production; TFF; tangential flow filtration; blood clots; automation; antibodies; latex immunoassay; LIA;

   Sammanfattning : To diagnose patients suffering from blood clotting disorders latex immununoassays (LIA) can be used. A time consuming manual tangential flow filtration (TFF) process suggests the implementation of an automatic TFF system to improve the efficiency, profitability, and expandability of the production facility of LIA at Nordic Biomarker.

5. 4. 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

7. 5. Vilken kvalitet håller nya bostäder?

   Kandidat-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

   Författare :Josef Citrohn; Sjöberg Joachim; [2022]
   Nyckelord :Daylight; axiality; tour; room organisation; potential for remaining resident; MAB; immersurable values; Dagsljus; axialitet; rundgång; rumsorganisation; potential för kvarboende; MAB; Omätbara värden;

   Sammanfattning : Flera kommuner runt om i Sverige rapporterar om att man har bostadsbrist. Orsaker tillatt det finns en bostadsbrist i Sverige är dels den höga byggkostnaden delsbefolkningsökning som sker. För att kunna möta upp bristen samt ökningen har detproducerats bostäder i en stor volym. LÄS MER
