A Job Recommendation System Based on Student and Category Similarity Computation

The expansion of enrollment in Chinese universities has further aggravated the pressure of graduates’ employment competition. Students have to spend lots of time seeking satisfactory jobs. There is a growing uncertainty in finding a job because education is biased toward basic knowledge, students lack both work experience and social background, and job market changes rapidly. Students tend to look for jobs that match their interests and skills. It’s difficult to apply traditional collaborative filtering recommendation algorithm directly. In this case, we adopt the method of recommendation based on students’ career preferences. Data collected from IT industry on 51job website are divided into 15 first-level categories and 246 second-level categories through a semi-manual method. After student information and job information are cleaned and captured by keywords, the degree of matching between the student and the second-level category is calculated, and interpretable recommendations are realized.

Correct Modeling of SH 50ETF Option Implied Volatility Based on Neural Network

We revealed some structural problems with the implied volatility surface (IVS) of Shanghai Stock Exchange (SSE) 50ETF options. First, there is a mismatch between call and put implied volatilities. Secondly, the SSE 50ETF lack short mechanism. Thirdly, the option data is sparse. With these problems, we are not able to apply some of the well-known models derived from the US market or other mature markets to the SSE 50ETF option directly. To solve this problem, we proposed several new modeling methods including a Neural Network approach, replacing the SSE 50ETF spot price with Shanghai 50 Index futures and interpolation methods. And after comparison, we find that, both interpolation methods and replacing ETF data with futures can improve the performance of traditional models and DNN methods performance the best in all scenarios.

High Dimensional Data Visualization Analysis Based on Unsupervised Laplacian Score

With the rapid development of big data technology and information visualization technology, the concept of data visualization is constantly evolving and developing. As one of the classic high-dimensional data visualization methods, the parallel coordinate axis has excellent plane geometric characteristics. However, as the amount of data increases and the dimension of the data feature increases, the number of polylines on the finite plane of the parallel coordinate graph also increases. The crossing and occlusion of lines lead to serious visual redundancy and clutter. This project uses the feature distribution and feature axis arrangement on the parallel axis as the research entry point, and uses two unsupervised feature selection methods (Laplacian Score and SVD-Entropy) to re-arrange the features on the PCP axis to improve parallelism. Phenomena such as data disorder and clutter on the coordinate axis. Furthermore, we proposed a plane geometry optimization CLS algorithm by combining two unsupervised feature selection algorithms and the PCP axis radius coverage calculation method. The proposed algorithm conforms to people's perception characteristics of information and plane space representation, and can help people more quickly analyze and understand data.

Multi-dimensional Convolutional Neural Network for Speech Emotion Recognition

Speech Emotion Recognition (SER) is a difficulty of deep learning algorithms. The difficulty is that people’s own understanding of emotions is not absolute. Different people may also have different judgments on the same speech. And speech emotion recognition plays a huge role in many real-time applications. With the continuous development of deep learning in recent years, many people use convolutional neural networks (CNN) to extract high-dimensional features in speech from speech spectrograms, thereby improving the accuracy of speech emotion recognition. In contrast, we propose a new model of speech emotion recognition. The model uses the eGeMAPS feature set extracted through the openSMILE toolkit to input into our model. The model learns the correlation and timing between features. In addition, we perform intra-class normalization on the input features to ensure more accurate recognition and faster data fitting. In our model, the key speech segments can be selected through the characteristics of convolutional neural network (CNN), so that the recognition accuracy of the model can achieve a better effect. Our model was evaluated experimentally in the IEMOCAP dataset. Experimental results show that our unweighted accuracy (UA) and weighted accuracy (WA) on the test set reached 60.9% and 63.0%.

Technology of Radial Fluid Enhanced Diffusion Based on Machine Learning

In the 1990s, it became easier for people to obtain digital information and to spread the information through the Internet. Against this background, machine learning has begun to develop vigorously, focusing more on solving practical problems. The phenomenon of radial fluid enhanced diffusion has always been the focus of attention in the field of fluid mechanics. However, due to the limitations of various actual physical conditions, convection dominates the radial fluid enhanced diffusion problem. The classic solution method will cause serious non-physical oscillations when solving the problem, and no more accurate numerical results can be obtained. Based on this, this paper proposes a radial fluid-enhanced diffusion technology based on machine learning. The logarithmic increment method is proposed to improve the non-parametric estimation of the drift coefficient. Experiments show that in the two typical models, the mean value of the logarithmic increment method fluctuates between 0.4–0.6, which is closer to the actual value of 0.495, indicating that the mean value of the logarithmic increment method is closer to the true value and the variance is smaller. The effect is better than that of the direct incremental method.

If it is not handled in time, it will also cause secondary accidents, which will have a serious impact on the operation of the whole urban expressway network. In this paper, an algorithm design based on Intelligent Transportation nonlinear dynamic control and automatic accident detection algorithm is proposed to improve the coverage and uncertainty of expressway incident detection.
