1. 1. A Study of the Loss Landscape and Metastability in Graph Convolutional Neural Networks

   Master-uppsats, KTH/Matematisk statistik

   Författare :Sofia Larsson; [2020]
   Nyckelord :Graph neural networks; Graph convolutional neural networks; Loss landscape; Gradient descent; Stochastic gradient descent; Stochastic gradient Langevin dynamics; Grafneurala nätverk; grafiska faltningsnätverk; lösningslandskap; gradientmetoder; stokastiska gradientmetoder; stokastisk gradient Langevin dynamik;

   Sammanfattning : Many novel graph neural network models have reported an impressive performance on benchmark dataset, but the theory behind these networks is still being developed. In this thesis, we study the trajectory of Gradient descent (GD) and Stochastic gradient descent (SGD) in the loss landscape of Graph neural networks by replicating Xing et al. LÄS MER

3. 2. P-SGLD : Stochastic Gradient Langevin Dynamics with control variates

   Master-uppsats, Linköpings universitet/Statistik och maskininlärning

   Författare :Andrea Bruzzone; [2017]
   Nyckelord :Big Data; Bayesian Inference; MCMC; SGLD; Estimated Gradient; Logistic Regression;

   Sammanfattning : Year after years, the amount of data that we continuously generate is increasing. When this situation started the main challenge was to find a way to store the huge quantity of information. LÄS MER
