   Nyckelord :Semi-Supervised Learning; Active Learning; Generative Models; Mixture Models; Semi-Övervakad Inlärning; Aktiv Inlärning; Generativa Modeller; Mixturmodeller;

   Sammanfattning : In many relevant scenarios, there is an imbalance between abundant unlabeled data and scarce labeled data to train predictive models. Semi-Supervised Learning and Active Learning are two distinct approaches to deal with this issue. LÄS MER

3. 2. General Attitudes and Mode Choice : A mode choice study in Stockholm using Schwartz value-items grouped by personal characteristics

   Master-uppsats, KTH/Transport och systemanalys

   Författare :Malin Andersson; [2021]
   Nyckelord :mode choice; modal choice; values; attitudes; Schwartz value scale; multinomial models; Random Forest; färdmedelsval; värderingar; attityder; Schwartz värdeobjekt; multinomiala modeller; Random Forest;

   Sammanfattning : Value-items from the Schwartz scale of Values have been added to travel data to investigate if the value-items can be used to model mode choice. Two kinds of mode choice models, both discrete choice models, multinomial models (MNL) and the Machine Learning Models Random Forests (RF) were constructed, using Travel Diary data (RVU) and additional data from European Social Survey (ESS).
