Combining Predictions under Uncertainty: The Case of Random Decision Trees

1 code implementation15 Aug 2022 Florian Busch, Moritz Kulessa, Eneldo Loza Mencía, Hendrik Blockeel

A common approach to aggregate classification estimates in an ensemble of decision trees is to either use voting or to average the probabilities for each class.

Correlation-based Discovery of Disease Patterns for Syndromic Surveillance

1 code implementation18 Oct 2021 Michael Rapp, Moritz Kulessa, Eneldo Loza Mencía, Johannes Fürnkranz

Early outbreak detection is a key aspect in the containment of infectious diseases, as it enables the identification and isolation of infected individuals before the disease can spread to a larger population.

Gradient-based Label Binning in Multi-label Classification

no code implementations22 Jun 2021 Michael Rapp, Eneldo Loza Mencía, Johannes Fürnkranz, Eyke Hüllermeier

Based on the derivatives computed during training, we dynamically group the labels into a predefined number of bins to impose an upper bound on the dimensionality of the linear system.

Revisiting Non-Specific Syndromic Surveillance

1 code implementation28 Jan 2021 Moritz Kulessa, Eneldo Loza Mencía, Johannes Fürnkranz

Infectious disease surveillance is of great importance for the prevention of major outbreaks.

Learning Structured Declarative Rule Sets -- A Challenge for Deep Discrete Learning

no code implementations8 Dec 2020 Johannes Fürnkranz, Eyke Hüllermeier, Eneldo Loza Mencía, Michael Rapp

Arguably the key reason for the success of deep neural networks is their ability to autonomously form non-linear combinations of the input features, which can be used in subsequent layers of the network.

Learning Gradient Boosted Multi-label Classification Rules

1 code implementation23 Jun 2020 Michael Rapp, Eneldo Loza Mencía, Johannes Fürnkranz, Vu-Linh Nguyen, Eyke Hüllermeier

In multi-label classification, where the evaluation of predictions is less straightforward than in single-label classification, various meaningful, though different, loss functions have been proposed.

On Aggregation in Ensembles of Multilabel Classifiers

no code implementations21 Jun 2020 Vu-Linh Nguyen, Eyke Hüllermeier, Michael Rapp, Eneldo Loza Mencía, Johannes Fürnkranz

While a variety of ensemble methods for multilabel classification have been proposed in the literature, the question of how to aggregate the predictions of the individual members of the ensemble has received little attention so far.

Simplifying Random Forests: On the Trade-off between Interpretability and Accuracy

no code implementations11 Nov 2019 Michael Rapp, Eneldo Loza Mencía, Johannes Fürnkranz

We analyze the trade-off between model complexity and accuracy for random forests by breaking the trees up into individual classification rules and selecting a subset of them.

Efficient Discovery of Expressive Multi-label Rules using Relaxed Pruning

1 code implementation19 Aug 2019 Yannik Klein, Michael Rapp, Eneldo Loza Mencía

Albeit the number of possible label combinations increases exponentially with the number of available labels, it has been shown that rules with multiple labels in their heads, which are a natural form to model local label dependencies, can be induced efficiently by exploiting certain properties of rule evaluation measures and pruning the label search space accordingly.

On the Trade-off Between Consistency and Coverage in Multi-label Rule Learning Heuristics

1 code implementation8 Aug 2019 Michael Rapp, Eneldo Loza Mencía, Johannes Fürnkranz

Many rule learning algorithms employ a heuristic-guided search for rules that model regularities contained in the training data and it is commonly accepted that the choice of the heuristic has a significant impact on the predictive performance of the learner.

Improving Outbreak Detection with Stacking of Statistical Surveillance Methods

no code implementations17 Jul 2019 Moritz Kulessa, Eneldo Loza Mencía, Johannes Fürnkranz

Our results on synthetic data show that it is challenging to improve the performance with a trainable fusion method based on machine learning.

Learning Interpretable Rules for Multi-label Classification

1 code implementation30 Nov 2018 Eneldo Loza Mencía, Johannes Fürnkranz, Eyke Hüllermeier, Michael Rapp

Multi-label classification (MLC) is a supervised learning problem in which, contrary to standard multiclass classification, an instance can be associated with several class labels simultaneously.

Analysis and Optimization of Deep Counterfactual Value Networks

no code implementations2 Jul 2018 Patryk Hopner, Eneldo Loza Mencía

Recently a strong poker-playing algorithm called DeepStack was published, which is able to find an approximate Nash equilibrium during gameplay by using heuristic values of future states predicted by deep neural networks.

Large-scale Multi-label Text Classification - Revisiting Neural Networks

no code implementations19 Dec 2013 Jinseok Nam, Jungi Kim, Eneldo Loza Mencía, Iryna Gurevych, Johannes Fürnkranz

Neural networks have recently been proposed for multi-label classification because they are able to capture and model label dependencies in the output layer.
