  1. 21. Decision Policies for Early Stage Clinical Trials with Multiple Endpoints

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Víctor López Juan; [2022-11-11]
    Keywords : clinical trials; early stage; multivariate; Lalonde;

    Abstract : Before a drug can be prescribed to patients, it must be shown to be safe and effective for a certain indication in a controlled clinical trial (known as Phase III). Such studies are costly to run and expose patients to potential risks. READ MORE

  3. 22. Cluster KL-UCB: Optimism for the Best, Pessimism for the Rest

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Emelie Lööf; [2022-06-28]
    Keywords : ;

    Abstract : The project presents an allocation strategy for the stochastic multi armed bandit when considering instances with a clustered structure. Using the architecture of the KL-UCB policy as a source of inspiration, an algorithm which exploits and takes advantage from a clustered structure is derived. READ MORE

  4. 23. Investigation of Information-Theoretic Bounds on Generalization Error

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Reza Qorbani; Kevin Pettersson; [2022]
    Keywords : Generalization error; ISMI; functional conditional mutual information; Generalization bound;

    Abstract : Generalization error describes how well a supervised machine learning algorithm predicts the labels of input data that it has not been trained with. This project aims to explore two different methods for bounding generalization error, f-CMI and ISMI, which explicitly use mutual information. READ MORE

  5. 24. A Game-theoretical Framework for Byzantine-Robust Federated Learning

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Wanyun Xie; [2022]
    Keywords : Game theory; distributed robust learning; training-time attacks; exploration-exploitation tradeoff; Spelteori; distribuerad robust inlärning; attacker på träningstiden; kompromiss mellan utforskning och exploatering;

    Abstract : The distributed nature of Federated Learning (FL) creates security-related vulnerabilities including training-time attacks. Recently, it has been shown that well-known Byzantine-resilient aggregation schemes are indeed vulnerable to an informed adversary who has access to the aggregation scheme and updates sent by clients.

  6. 25. Adaption of Inertial Confinement Fusion Resultsto Spherical Plasma Expansion at Comets

    University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Author : Viktor Sparrman; [2022]
    Keywords : Plasma; Inertial confinement fusion; comet; plasma expansion; Vlasov-Poisson; integral invariants; ergodicity;

    Abstract : Recent missions to solar system comets, such as ESA's Rosetta mission, raise interest for models and descriptions of their plasma environment. The interaction with various space phenomena such as stellar wind make the construction of an analytical description difficult. READ MORE
