  1. 1. Classifying Google reCAPTCHA v2 - A study using transfer learning models and evaluating their robustness against adversarial perturbations

    University essay from Lunds universitet/Statistiska institutionen; Lunds universitet/Nationalekonomiska institutionen

    Author : Arvid Björklund; Marius Uogele; [2023]
    Keywords : reCAPTCHA; transfer learning; adversarial perturbations; convolutional neural network; Business and Economics;

    Abstract : This thesis seeks to examine the suitability and robustness of transfer learning models in creating an efficient reCAPTCHA v2 classifier, and further evaluates their performance against various adversarial attacks. Three models - DenseNet201, EfficientNetV2, and InceptionV3 - were trained and assessed, highlighting the applicability of transfer learning techniques in the classification of reCAPTCHA v2 challenges.

  2. 2. 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.
