  1. 11. Noise Robustness of Convolutional Autoencoders and Neural Networks for LPI Radar Classification

    University essay from KTH/Matematisk statistik

    Author : Gustav Norén; [2020]
    Keywords : LPI radar; CNN; autoencoder; noise robustness; denoising; LPI radar; CNN; autoencoder; brustålighet; avbrusning;

    Abstract : This study evaluates noise robustness of convolutional autoencoders and neural networks for classification of Low Probability of Intercept (LPI) radar modulation type. Specifically, a number of different neural network architectures are tested in four different synthetic noise environments. READ MORE

  3. 12. Impact of observation noise and reward sparseness on Deep Deterministic Policy Gradient when applied to inverted pendulum stabilization

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

    Author : Adam Björnberg; Haris Poljo; [2019]
    Keywords : ;

    Abstract : Deep Reinforcement Learning (RL) algorithms have been shown to solve complex problems. Deep Deterministic Policy Gradient (DDPG) is a state-of-the-art deep RL algorithm able to handle environments with continuous action spaces. READ MORE

  4. 13. Localisation and mapping in smoke filled environments : A study of robot perception in harsh conditionsusing practical experiments

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Martin Zakardissnehf; Agnes Jernström; [2017]
    Keywords : autonomous navigation; SLAM; perception in smoke; autonom navigering; SLAM; perception i r¨ok;

    Abstract : Det här examensarbetet är utfört i samarbete med Realisator Robotics, vilka förtillfället utvecklar en robot, FUMO, som ska hjälpa till vid brandbekämpning. Målet med examensarbetet är att implementera autonom navigering från en punkt till en annan samt SLAM (Simultaneous Localisation and Mapping, simultan lokaliseringoch kartläggning) funktionalitet.

  5. 14. Natural image distortions and optical character recognition accuracy

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Filip Lundqvist; Olle Wallberg; [2016]
    Keywords : ;

    Abstract : Current state of the art optical character recognition tools are trained using high quality image datasets. In practical applications, natural images used for character recognition willnot always be of high quality. READ MORE

  6. 15. Task Load Modeling for LTE Baseband Signal Processing with Regression Analysis Approach

    University essay from KTH/Signalbehandling

    Author : Chang Liu; [2014]
    Keywords : ;

    Abstract : In telecommunication baseband signal processing systems, thousands of tasks are executed every millisecond. These tasks take in dierent parameters and cause heavy load to the system. The aim of the thesis is to build proper mathematical models for these tasks, enabling the prediction of their load given the corresponding parameters. READ MORE
