### Machine Learning

Machine Learning is currently one of the hottest topics in computer science. Almost daily we find new press releases about groundbreaking improvements in a wide field of applications, comprising e.g. Object Recognition, Speech Recognition, Automatic Translation, Digital Assistents, Robotics, Autonomous Driving, Intelligent Web-Search, Recommendation Systems, Computer Games and many more. Global Players such as Google, Apple, Facebook, IBM, Bosch, Daimler but also many medium-sized enterprises have been recognized the potential of intelligent, self-learning systems (see e.g. Die Zeit - Interview Sebastian Thrun).

*So, what is Machine Learning?*
Machine Learning is the science of building computer systems that can automatically improve with experience. In contrast to conventional computer systems, adaptive systems that integrate Machine Learning algorithms do not only process data according to a manually programmed sequence of instructions. ML systems learn and adapt the way how they process data automatically. These adaptations are based on the learned knowledge (experience). The learning process requires usually large amounts of data. If there are latent correlations or patterns the learning algorithms will find them and integrate the corresponding knowledge in their processing-model.

This lecture provides an introduction in the currently most relevant machine learning algorithms and their applications. All categories of machine learning - Supervised learning, Unsupervised learning, Reinforcement learning - are covered. Fundamental concepts e.g. on training, test and evaluation in general, are covered as well as well established conventional algorithms (e.g. Support Vector Machines) and the recently top performing Deep Learning algorithms.
