1. 1. Java Syntax Error Repair Using RoBERTa

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

   Author : Ziyi Xiang; [2022]
   Keywords : Java program repair; RoBERTa; Neural machine translation architecture; Reparation av Java­program; RoBERTa; Neural maskinöversättningsarkitektu;

   Abstract : Deep learning has achieved promising results for automatic program repair (APR).In this paper, we revisit this topic and propose an end-to-end approach Classfix tocorrect java syntax errors. Classfix uses the RoBERTa classification model to localizethe error, and uses the RoBERTa encoder-decoder model to repair the located buggyline. READ MORE

3. 2. A comparison of genetic algorithm and reinforcement learning for autonomous driving

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

   Author : Ziyi Xiang; [2019]
   Keywords : Thesis; Machine learning; Genetic algorithm; Deep reinforcement learning; Autonomous driving; Thesis; Maskininlärning; Genetisk algoritm; Djup förstärkning lärande; självkörandebilar;

   Abstract : This paper compares two different methods, reinforcement learning and genetic algorithm for designing autonomous cars’ control system in a dynamic environment. The research problem could be formulated as such: How is the learning efficiency compared between reinforcement learning and genetic algorithm on autonomous navigation through a dynamic environment? In conclusion, the genetic algorithm outperforms the reinforcement learning on mean learning time, despite the fact that the prior shows a large variance, i. READ MORE
