Combining Instance-Based Learning and Logistic Regression for Multi-Label Classification
Weiwei Cheng
Video in druga učna gradiva
Oznake: computer science;machine learning
Multilabel classification is an extension of conventional classification in which a single instance can be associated with multiple labels. Recent research has shown that, just like for conventional classification, instance-based learning algorithms relying on the nearest neighbor estimation princip ...

Learning Monotone Nonlinear Models using the Choquet Integral
Weiwei Cheng
Video in druga učna gradiva
Oznake: computer science;machine learning
The learning of predictive models that guarantee monotonicity in the input variables has received increasing attention in machine learning in recent years. While the incorporation of monotonicity constraints is rather simple for certain types of models, it may become a more intricate problem for oth ...

Decision Tree and Instance-Based Learning for Label Ranking
Weiwei Cheng
Video in druga učna gradiva
Oznake: computer science;machine learning
The label ranking problem consists of learning a model that maps instances to total orders over a finite set of predefined labels. This paper introduces new methods for label ranking that complement and improve upon existing approaches. More specifically, we propose extensions of two methods that hav ...

Label Ranking with Abstention: Predicting Partial Orders by Thresholding Probability Distributions
Weiwei Cheng
Video in druga učna gradiva
Oznake: astronomy;cosmology
We consider an extension of the setting of label ranking, in which the learner is allowed to make predictions in the form of partial instead of total orders. Predictions of that kind are interpreted as a partial abstention: If the learner is not sufficiently certain regarding the relative order of t ...
