Become Part of the Artificial Intelligence Revolution

What you'll learn
Learn how to program in Python
Discover machine learning
Use artificial intelligence in your programs
Learn how to analyse data and make predictions

Requirements
Only basic computer knowledge needed
Basic algebra knowledge useful, but not required

Description
This course teaches you computer programming in Python from scratch, and also the basics of machine learning in Python.With this course you can become part of the Artificial Intelligence revolution.You'll learn:How to write programs in PythonThe basics of desktop programming in PythonObject-oriented programming and functional programming techniquesHow to use machine learning techniques in your codeThe basics of visualising and analysing dataNumpy, Pandas, Matplotlib, scikit-learn, Keras and morePowerful prediction and classification techniques "naive Bayes" and decision trees.How to use ML techniques to make predictions about data series, spot clusters in data, automatically classify data samples and recognise handwritten digits.Whether you're a complete beginner with coding or already know some Python or another language, this course can help give you modern computer skills to the point where you could apply for Python jobs, where available.Python is one of the most popular programming languages today and is especially popular because of its support for machine learning and artificial intelligence.This courses takes you all the way from writing your first "hello world" Python program to being able to write complex programs incorporating artificial intelligence techniques in which your software can automatically learn how to complete tasks.I'll type all code right in front of you and explain how it works, breaking down programming and mathematical concepts into simple steps, and with suggested exercises throughout.
