Learning from the Best - Visual Analysis of a Quasi-Optimal Data Labeling Strategy [article]

Jürgen Bernard, Marco Hutter, Markus Lehmann, Martin Müller, Matthias Zeppelzauer, Michael Sedlmair
2018 Eurographics Conference on Visualization  
In this work, we focus on the analysis of a (theoretical) quasi-optimal, ground-truth-based strategy for labeling instances, which we refer to as the upper limit of performance (ULoP).  ...  Results show that the strategy of ULoP is not constant (as in most state-of-the-art active learning strategies) but changes within the labeling process.  ...  To simulate a quasi-optimal labeling strategy, our ULoP strategy is modeled by executing a greedy search for instances based on ground truth data.  ...

Quasi-supervised learning for biomedical data analysis

Bilge Karaçalı
2010 Pattern Recognition  
The fitness of the method in biomedical data analysis was further demonstrated on real multi-color flow cytometry and multi-channel electroencephalography data.  ...  We adopt a binary recognition scenario where a control dataset contains samples of one class only, while a mixed dataset contains an unlabeled collection of samples from both classes.  ...  In the literature, quasi-supervised learning refers to learning strategies that deal with prominently unlabeled data, where some labels are available and only through indirect user interaction [7, 8]  ...

Combining Low-Density Separators with CNNs

Adopting Robustness and Optimality in Fitting and Learning [article]

Zhiguang Wang, Tim Oates, James Lo
2015 arXiv   pre-print
We generalized a modified exponentialized estimator by pushing the robust-optimal (RO) index λ to -∞ for achieving robustness to outliers by optimizing a quasi-Minimin function.  ...  Optimality is guaranteed by expansion of the convexity region in the Hessian matrix to largely avoid local optima. Detailed quantitative analysis on both robustness and optimality are provided.  ...  As a general error estimator, we provide a quantitative analysis and validate its effectiveness on three function fitting and one visual recognition tasks.  ...

Improving One-Shot Learning through Fusing Side Information [article]

Yao-Hung Hubert Tsai, Ruslan Salakhutdinov
2018 arXiv   pre-print
Deep Neural Networks (DNNs) often struggle with one-shot learning where we have only one or a few labeled training examples per category.  ...  First, we propose to enforce the statistical dependency between data representations and multiple types of side information.  ...  Instead of learning the networks exclusively from data, we extend the training from data and side information jointly.  ...
