  1. 1. Unsupervised 3D Human Pose Estimation

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

    Author : Sri Datta Budaraju; [2021]
    Keywords : Computer Vision; Projective Geometry; Deep Learning; Unsupervised Learning; 3D Human Pose Estimation; GAN; AutoEncoder; Hybrid Generative Model; Self Supervision;

    Abstract : The thesis proposes an unsupervised representation learning method to predict 3D human pose from a 2D skeleton via a VAEGAN (Variational Autoencoder Generative Adversarial Network) hybrid network. The method learns to lift poses from 2D to 3D using selfsupervision and adversarial learning techniques. READ MORE

  2. 2. Improving Zero-Shot Learning via Distribution Embeddings

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

    Author : Vivek Chalumuri; [2020]
    Keywords : Zero-Shot Learning ZSL ; Generalized Zero-Shot Learning GZSL ; Image Classification; Metric Learning; Distribution Embeddings; Triplet Loss; Zero-shot lärande; Generaliserat zero-shot-lärande; Bildklassificering; Metrisk inlärning; Distribution inbäddningar; Triplet-förlust;

    Abstract : Zero-Shot Learning (ZSL) for image classification aims to recognize images from novel classes for which we have no training examples. A common approach to tackling such a problem is by transferring knowledge from seen to unseen classes using some auxiliary semantic information of class labels in the form of class embeddings.

  3. 3. Robust Descriptor Learning Using Variational Auto-Encoders

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

    Author : Leonidas Valavanis; [2020]
    Keywords : ;

    Abstract : Image matching is the task of finding points in one image corresponding to the same points in the other image. Classical feature descriptors fail to match points when the images are under extreme viewpoint or seasonal changes. This thesis tackles the problem of image matching when two images are under severe changes. READ MORE

  4. 4. Semi-supervised Lesion Detection via Image Restoration

    University essay from Lunds universitet/Matematik LTH

    Author : Jonatan Kronander; [2020]
    Keywords : Mathematics and Statistics;

    Abstract : Lesion detection is a critical task for medical image understanding. While the problem has been widely addressed in a supervised semantic segmentation manner, the problem clinically appears more similar to novelty detection with few or no annotations for the lesion. READ MORE

  5. 5. Unsupervised state representation pretraining in Reinforcement Learning applied to Atari games

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

    Author : Francesco Nuzzo; [2020]
    Keywords : ;

    Abstract : State representation learning aims to extract useful features from the observations received by a Reinforcement Learning agent interacting with an environment. These features allow the agent to take advantage of the low-dimensional and informative representation to improve the efficiency in solving tasks. READ MORE
