摘要：

We present our methods and results on participating in the Inter speech 2014 Computational Paralinguistics ChallengE (ComParE) of which the goal is to detect certain type of load of a speaker using acoustic features. There are in total seven classification models contributing to our final prediction, namely, neural network with rectified linear unit and dropout (ReLUNet), conditional restricted Boltzmann machine (CRBM), logistic regression (LR), support vector machine (SVM), Gaussian discriminant analysis (GDA), k-nearest neighbors (KNN), and random forest (RF). When linearly blending the predictions of these models, we are able to get significant improvements over the challenge baseline.
