Title of Keynote speech：Traffic Classification based on Machine Learning Methods

Abstract

The present era is the era of artificial intelligence. Machine learning is the pearl on the AI crown. Machine learning methods have already been deployed widely in many fields, such as natural language processing, image processing, bioinformatics, etc. In computer networks and information security, machine learning based methods have also played a important role. In Internet traffic classification, machine learning based methods identify encrypted traffic and proprietary protocols effectively based on statistical features of traffic flows. However, changes of network environment lead to performance degradation of traffic classification based on traditional machine learning models. To tackle these problems, incremental learning methods and transfer learning have attracted increasing attention as they both achieve the state of art performance in traffic classification and have their own characteristics compared with other machine learning methods. Incremental SVMs model is introduced to reduce the high training cost of memory and CPU, and to realize traffic classifier's high-frequency and quick updates. TrAdaBoost for multi-class task is utilized to transfer the knowledge from source domain into target domain in traffic classification.

Title of keynote speech: Local fractional calculus applied to model the mathematical problems in fractal engineering

Abstract 

In this talk, we mainly introduce the concepts and properties of local fractional derivative and local fractional integral. The local fractional diffusion equation in the fractal heat-transfer is discussed in detail. The computational methods for the model, such as local fractional Fourier series, local fractional Laplace type integral transforms and local fractional Fourier type integral transforms are considered to handle the above problem and the solutions of the model with are obtained in detail. The local fractional calculus is accurate and efficient for modelling the mathematical problems in fractal engineering.
