The topic of my talk is "Artificial Intelligence: from theory to practice".    My aim for the talk is to highlight AI techniques that have been widely used in the industry.  I will give a bit of background on the modern AI techniques, particulary the machine learning aspect. The applications of these techniques in many areas will be illustrated.  Therefore I will mention Deep learning, Convolutional neural networks, and other techniques.  In the end I want to mention about the future of AI.
