Introduction to machine learning

Course Dates: 12/04/21 - 13/05/21
Time: 19:00 - 20:30
Location: Online

One of the great advances in technology is that machines can learn without humans teaching them explicit rules – e.g. letting machines train on samples of speech allows Siri to recognise your commands. Machine learning is a large part of artificial intelligence, and a mystery to most of us. This practical course teaches you how to program learning algorithms in Python. We will cover fundamentals of classification, natural language processing, financial predictions and much more. You will learn elements of data mining, how to choose a learning algorithm, and how to tweak parameters of the algorithm. We will briefly cover the theory behind the algorithms, so some maths knowledge is useful, but not required. To enrol, you must have experience with Python or a similar programming language, e.g. have taken City Lit’s Introduction to Python or Introduction to R programming course.

What is the course about?

The course serves as a practical guide on how to program machine learning. It will cover some of the most common learning methods. Explanations of how the learning algorithms work will be provided, but the main emphasis is on how they are implemented in practice. The course will briefly cover learning algorithms for images, but most of the course will consider data frames containing words and numbers. This course has an ambitious curriculum – you should be prepared for a somewhat high-paced course, but ample support will be given along the way.

This is a live online course. You will need:
- Internet connection. The classes work best with Chrome.
- A computer with microphone and camera.
- Earphones/headphones/speakers.
We will contact you with joining instructions before your course starts.

What will we cover?

Each session treats a different aspect of machine learning.

Session 1: Introduction to machine learning - quick history, how it is used today, and data pre-processing. Handling missing values, encoding variables etc. We will spend some time getting familiar with data frames in Python. Elements of natural language processing.

Session 2: Common regression and classification methods with emphasis on random forest and boosted decision trees. Basics of learning algorithms. How loss functions work and optimisation of these. Choices of hyperparameters.

Session 3: Artificial neural nets - how to determine neural net architecture and hyperparameters. Will briefly cover image processing and convolutional neural networks.

Session 4: Unsupervised machine learning and summary, including k-means clustering. Explanation of some unsupervised learning methods with an emphasis on k-means clustering. Summary of common machine learning methods and outline of when to use what. Guidance on how to explore machine learning further.

What will I achieve?
By the end of this course you should be able to...

• Pre-process your data using some common methods
• Program simple learning algorithms in Python using random forest, boosted decision trees, neural nets, and k-means clustering
• Make informed decisions on choosing variables and tweaking hyperparameters
• Explore machine learning further in an informed manner.

What level is the course and do I need any particular skills?

This course is aimed at people with some programming experience, but no machine learning experience. You must have programmed in Python, R, or a similar language before. You should be comfortable with e.g. for-loops and if-statements. You must be comfortable using a computer. Some mathematical understanding is favourable, but not necessary.

How will I be taught, and will there be any work outside the class?

The session consist of a combination of presentations and coding. This is a practical course with an emphasis on implementing what you learn. There will therefore be homework after each week where you explore what you learnt in class in more depth. There will be room for you to explore your topics of interest in several of these. A larger project will be assigned after the third week. If you cannot complete any homework, you are still welcome to join the course, but be aware that you may lose out on some of learning outcomes.

Are there any other costs? Is there anything I need to bring?

For this course you must install Python and Jupyter on your computer, in addition to several libraries as instructed in class. Your computer must have some space for somewhat large data sets. Notes will be provided electronically via Google Classroom. It’s a good idea to have a pen and paper for your own notes.

When I've finished, what course can I do next?

Linear algebra and optimisation for machine learning, machine learning: intermediate, data science with Python.

Liv is a physicist with background in machine learning. She completed her masters degree at University College London, with a thesis in theoretical astrophysics, and is currently working on a PhD in particle physics at Imperial College. She first started exploring machine learning at the Wolfram Summer School in Boston, and has since done internships with BT in the UK and DESY in Germany. Her PhD centrers around using novel methods for high performance computing and machine learning for the upgrade of the compact muon solenoid experiment at CERN in Switzerland.
