Machine Learning

I am passionate about machine learning and related fields.

 

My interests are:

  • Preference Learning
  • Meta-Learning
  • Intelligent Decision Making / Reinforcement Learning
  • Computer Vision

The ML methods I am currently interested are:

  • Probabilistic Ranking Models
  • (Deep) Neural Networks
  • Online Algorithms (for Large Scale Applications)
  • Genetic Algorithms
  • Visualization techniques

Ranking of Paired Data

For the purpose of learning from and the prediction of preferences I worked on a new supervised learning setting called dyad ranking (see thesis).

 

The following problems can be tackled with it:

  • Classification (binary, multi-class, multi-label)
  • Similarity Learning
  • (Label) Ranking

Related settings are:

  • Learning to Rank for Information Retrieval
  • Collaborative Filtering & Ranking
  • Dyadic Prediction
  • Zero-shot Learning
