1. 1. Determining Protein Conformational Ensembles by Combining Machine Learning and SAXS

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Samuel Eriksson Lidbrink; [2023]
   Nyckelord :AlphaFold; AlphaFold2; SAXS; protein conformational ensembles; machine learning; protein conformations; reweighting; SAXS; AlphaFold; AlphaFold2; proteinkonformationsensembler; maskininlärning; proteinkonformationer; omviktning;

   Sammanfattning : In structural biology, immense effort has been put into discovering functionally relevant atomic resolution protein structures. Still, most experimental, computational and machine learning-based methods alone struggle to capture all the functionally relevant states of many proteins without very involved and system-specific techniques.

3. 2. Learning from noisy labelsby importance reweighting: : a deep learning approach

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Tongtong Fang; [2019]
   Nyckelord :noisy label; importance reweighting; deep learning; domain adaptation; annoterad data; omviktning; djupt lärande; domänanpassning;

   Sammanfattning : Noisy labels could cause severe degradation to the classification performance. Especially for deep neural networks, noisy labels can be memorized and lead to poor generalization. LÄS MER
