<p>For the question that <strong>&ldquo;Why is Thread instead of Process in ‘4 Core 8 Thread&rsquo; ?”</strong> in PDF</p>
<p>Firstly,a point should be clearly,which is that <strong>Thread in &lsquo;4 Core 8 Thread&rsquo; is different with Thread in operating system</strong>.The former refers to the <strong>physical unit</strong> in the CPU, the latter refers to the <strong>logical unit</strong> in the operating system, so the problem does not hold!</p>

<h1 id="abstract">Abstract</h1>
<p>We introduce Collie,an online platform to assess the quality of nursing home service powered by machine learning, which enables user to choose a serial of selected algorithms for different demand. Previous research has proposed the point on how to measure the quality of nursing home service. But traditional service relies on manual investigation which present serval problems like the process of rating quality is complex and insufficient. For the above problems, Collie focus on supporting users to assess the quality of nursing home service. Within the service assessment, we develop a serial of algorithms to deal with different dataset. But more importantly, different database has different features, a group of algorithms is not enough to fulfill users demand. Therefore, we propose a system which enables users choose highly competitive algorithms to solve their problem. To support the core idea, we provide a high performance infrastructure features asynchronous I/O, fast and error tolerant data pipeline. Through a series of experiments, we show that our system outperforms the baseline significantly in terms of system performance, algorithm accuracy. Promising result has been retrieved from our algorithm which indices MAE of 0.5 at sample dataset.</p>

<h1 id="abstract">Abstract</h1>
<p>Automatically detecting emotional state in human speech, which plays an effective role in areas of human machine interactions, has been a difficult task for machine learning algorithms. Previous work for emotion recognition have mostly focused on the extraction of carefully hand-crafted and tailored features. Recently, spectrogram representations of emotion speech have achieved competitive per- formance for automatic speech emotion recognition. In this work we propose a method to tackle the problem of deep features, herein denoted as deep spectrum features, extraction from the spectrogram by leveraging Attention-based Bidirectional Long Short-Term Mem- ory Recurrent Neural Networks with fully convolutional networks. The learned deep spectrum features are then fed into a deep neural network (DNN) to predict the final emotion. The proposed model is then evaluated on the Interactive Emotional Dyadic Motion Cap- ture (IEMOCAP) dataset to validate its effectiveness. Promising results indicate that our deep spectrum representations extracted from the proposed model perform the best, 65.2% for weighted accuracy and 68.0% for unweighted accuracy when compared to other existing methods. We then compare the performance of our deep spectrum features with two standard acoustic feature repre- sentations for speech-based emotion recognition. When combined with a support vector classifier, the performance of the deep feature representations extracted are comparable with the conventional features. Moreover, we also investigate the impact of different fre- quency resolutions of the input spectrogram on the performance of the system.</p>

<h1 id="abstract">Abstract</h1>
<p>Automatic emotion recognition from speech, which is an important and challenging task in the field of affective computing, heavily relies on the effectiveness of the speech features for classification. Previous approaches to emotion recognition have mostly focused on the extraction of carefully hand-crafted features. How to model spatio-temporal dynamics for speech emotion recognition effectively is still under active investigation. In this paper, we propose a method to tackle the problem of emotional relevant feature extraction from speech by leveraging Attention-based Bidirectional Long Short-Term Memory Recurrent Neural Networks with fully convolutional networks in order to automatically learn the best spatio-temporal representations of speech signals. The learned high-level features are then fed into a deep neural network (DNN) to predict the final emotion. The experimental results on the Chinese Natural Audio-Visual Emotion Database (CHEAVD) and the Interactive Emotional Dyadic Motion Capture (IEMOCAP) corpora show that our method provides more accurate predictions compared with other existing emotion recognition algorithms.</p>
