  1. 1. Generating an Interpretable Ranking Model: Exploring the Power of Local Model-Agnostic Interpretability for Ranking Analysis

    Magister-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Laura Galera Alfaro; [2023]
    Nyckelord :Explainable Artificial Intelligence; Learning To Rank; Local ModelAgnostic Interpretability; Ranking Generalized Additive Models;

    Sammanfattning : Machine learning has revolutionized recommendation systems by employing ranking models for personalized item suggestions. However, the complexity of learning-to-rank (LTR) models poses challenges in understanding the underlying reasons contributing to the ranking outcomes. LÄS MER

  2. 2. Decreasing Training Time of Reinforcement Learning Agents for Remote Tilt Optimization using a Surrogate Neural Network Approximator

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

    Författare :Jiaming Huang; [2023]
    Nyckelord :;

    Sammanfattning : One possible application of reinforcement learning in the telecommunication field is antenna tilt optimization. However, one of key challenges we face is that the use of handcrafted simulators as environments to provide information for agents is often time-consuming regarding training reinforcement learning agents.

  3. 3. The Surrogate State? : The Role and Capacity of Non-State Organizations in Substituting the Responsibilities of the State for Providing Education to Venezuelan Refugee Children in Trinidad and Tobago

    Master-uppsats, Lunds universitet/LUMID International Master programme in applied International Development and Management; Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi

    Författare :Suzu Kitayama; [2023]
    Nyckelord :Refugee education; Surrogate State; Venezuelan refugee children; Non-state organizations; Education policy; International convention; State sovereignty; Social Sciences;

    Sammanfattning : According to the 1951 Refugee Convention, it is the state’s responsibility to protect and provide basic services to the refugees within their border. However, even if ratified to the Convention, it is common that the state decides to relinquish its responsibilities for various reasons. LÄS MER

  4. 4. Active Learning for Solving Expensive Optimization Problems

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Siwei Fu; [2022]
    Nyckelord :;

    Sammanfattning : Many practical engineering and computer science problems can be translated into a global otimization problem where the task is to find the best (optimal) vector 𝒙𝒙∗ that gives the smallest possible function value 𝑓𝑓 = 𝑓𝑓(𝒙𝒙∗) for some function 𝑓𝑓() of interest. Often the function 𝑓𝑓() is expensive in the sense that it cannot be easily evaluated computationally or experimentally in terms of time and/or resources required. LÄS MER

  5. 5. Chelating agents in NiMo sulfided catalysts and the effect of nitrogen compounds on hydrodearomatization and hydrodenitrogenation reactions

    Master-uppsats, KTH/Kemiteknik

    Författare :Lilla Lukovicsová; [2022]
    Nyckelord :hydrotreating; NiMo Al2O3; HDN; HDA; trickle-bed microreactor; Type I and II hydrotreating catalysts; Hydrering; NiMo Al2O3; HDN; HDA; porlbädd reaktor; Typ I och II hydrering katalysatorer;

    Sammanfattning : Hydrering är en viktig process för att producera produkter med önskade egenskaper samt att uppfylla de lagliga krav som existerar med avseende på miljö och hälsa. Reaktionerna som sker vid hydreringen är katalytiska vilket innebär att förstå sam utnyttja de mest lämpliga katalysatorerna är av yttersta vikt. LÄS MER
