Statistical Tests Using Hinge/ε-Sensitive Loss
TL;DR: This work discusses how the paired t test can use the hinge (e-sensitive) loss and shows that doing that, it can detect differences that the test on error cannot detect, indicating higher power in distinguishing between the behavior of kernel-based classifiers (regressors).

Distributed Decision Trees.
Ozan Irsoy,Ethem Alpaydin +1 more
TL;DR: This work extends the budding tree and proposes the distributed tree where the children use different and independent splits and hence multiple paths in a tree can be traversed at the same time, giving the power of a distributed representation, as in a traditional perceptron layer.
Proceedings ArticleDOI
Comparing distributed and local neural classifiers for the recognition of Japanese phonemes
TL;DR: The comparative performances of distributed and local neural networks for the speech recognition problem is investigated and the backpropagation rule is used with three error measures: mean square error, cross entropy, and combinational performance.
Proceedings ArticleDOI
Data Sampling and Dimensionality Reduction Approaches for Reranking ASR Outputs Using Discriminative Language Models
TL;DR: This paper investigates various approaches to data sampling and dimensionality reduction for discriminative language models (DLM), and exploits ranking perceptron and ranking SVM as two alternative discrim inative modeling techniques, and applies data sampling to improve their efficiency.
MonographDOI
