This paper presents a deep learning method application to the extraction of emotions included in Chinese speech with a deep belief network (DBN) structure. Eight proper features such as pitch, mel frequency cepstrum coefficient (MFCC) are chosen from Mandarin speech used as network inputs, and a DBN classifier is used instead of traditional shallow learning methods to recognition of emotions. Experiment studies have proven that its recognition rate is higher than that of the traditional back propagation (BP) method and support vector machine (SVM) classifier.

Feature subset selection is an important approach to deal with high-dimensional data. But selecting the best subset of data is NP hard. So most of feature selection methods cannot handle high-dimensional data efficiently, or they can only obtain local optimum instead of global optimum. In these cases, when the data consist of both labeled and unlabeled data, semi-supervised feature selection can make full use of data information. In this paper, we introduce a novel semi-supervised feature selection algorithm, which is a filter method based on Fisher-Markov selector, thus ours can achieve global optimum and computational efficiency under certain kernels.

This paper proposes a new algorithm for imaging moving targets via estimating their motion parameters with dual channel synthetic aperture radar. Displaced phase center array (DPCA) antennas are used for clutter cancelation through which moving targets are detected. The range motion of a moving target induces a Doppler centroid shift and additional range walk, while the along-track motion changes the Doppler modulation rate. The Doppler centroid shift dislocates the moving target from its actual azimuth position, and the additional range walk deteriorates the imaging resolution. The slope angle of the range walk trajectory is estimated via Hough transform, then the range velocity can be obtained. Doppler parameters of the moving targets are estimated with the fractional Fourier transform (FrFT). In this way, both target range and azimuth velocities are acquired. Next, the moving targets are focused with one uniform imaging algorithm. Simulated data processing results are provided to demonstrate the effectiveness of the proposed algorithm.
