This document provides an overview of computer vision, machine learning, and deep learning with Python. It introduces computer vision and some example applications like optical character recognition and face detection. It then discusses machine learning and how it can be applied to computer vision problems. Deep learning is introduced as a type of machine learning using artificial neural networks. Examples of successful deep learning applications are presented, including speech recognition and the AlphaGo program that mastered the game of Go. Finally, Python is discussed as a programming language well-suited for scientific and deep learning applications due to supporting libraries like NumPy, Scipy, and Matplotlib.

- 10. MACHINE LEARNING Machine learning is programming computers to optimize a performance criterion using example data or past experience. There is no need to “learn” to calculate payroll Learning is used when: Human expertise does not exist (navigating on Mars), Humans are unable to explain their expertise (speech recognition) Solution changes in time (routing on a computer network) Solution needs to be adapted to particular cases (user biometrics)

- 22. WHAT IS PYTHON? General purpose interpreted programming language Widely used by scientists and programmers of all stripes Supported by many 3rd-party libraries (currently 21,054 on the main python package website) Free!
- 23. WHY IS IT WELL-SUITED TO SCIENCE? NumPy Numerical library for python Written in C, wrapped by python Fast Scipy Built on top of NumPy (i.e. Also fast!) Common maths, science, engineering routines Matplotlib Hugely flexible plotting library Similar syntax to Matlab Produces publication-quality output
- 24. WHY IS PYTHON BETTER THAN WHAT I USE NOW? It can do everything Fast mathematical operations Easy file manipulation Format conversion Plotting Scripting Command line OK, not everything Write thesis for you
- 25. Python has a wide range of deep learning-related libraries available Low level High level (efficient gpu-powered math) (theano-wrapper, models in python code, abstracts theano away) (wrapper for theano, yaml, experiment-oriented) (computer-vision oriented DL framework, model-zoo, prototxt model definitions) pythonification ongoing! (theano-extension, models in python code, theano not hidden) and of course:
