# FYS-STK3155/4155 Applied Data Analysis and Machine Learning, http://www.uio.no/studier/emner/matnat/fys/FYS-STK4155/index-eng.html
|
||
|
||
|
||
This site contains all material relevant for the course on Data Analysis and Machine Learning FYS-STK3155/4155.
|
||
|
||
## Course content
|
||
|
||
Probability theory and statistical methods play a central role in science. Nowadays we are
|
||
surrounded by huge amounts of data. For example, there are about one trillion web pages; more than one
|
||
hour of video is uploaded to YouTube every second, amounting to 10 years of content every
|
||
day; the genomes of 1000s of people, each of which has a length of more than a billion base pairs, have
|
||
been sequenced by various labs and so on.
|
||
This deluge of data calls for automated methods of data analysis,
|
||
which is exactly what machine
|
||
learning provides. In this course the approach is to define machine learning as a set of methods that can
|
||
automatically detect patterns in data, and then use the uncovered patterns to predict future
|
||
data, or to perform other kinds of decision making under uncertainty. Since many of these problems can be studied using
|
||
tools of probability theory, the aim of this course is to expose you to central methods in probability theory linked with machine learning.
|
||
|
||
This course covers thus topics like Monte Carlo methods and Markov chains, Bayesian statistics, error estimates, various regression methods, optimization of data and error analysis and central algorithms in machine learning.
|
||
The course has several numerical projects and numerical exercises that are meant to illustrate the theory.
|
||
|
||
|
||
|
||
## Learning outcomes
|
||
|
||
The course introduces a variety of central algorithms and methods
|
||
essential for studies of data analysis and machine learning. The course is project based and through the various projects, normally three, the students will be exposed to fundamental research problems in these fields, with the aim to reproduce state of the art scientific results. Both supervised and unsupervised methods will be covered. You will learn to develop and structure large codes for studying these systems, get acquainted with computing facilities and learn to handle large scientific projects. A good scientific and ethical conduct is emphasized throughout the course. More specifically, after this course you will
|
||
|
||
- Learn about basic data analysis, statistical analysis, Monte Carlo sampling, data optimization and machine learning;
|
||
- Be capable of extending the acquired knowledge to other systems and cases;
|
||
- Have an understanding of central algorithms used in data analysis and machine learning;
|
||
- Gain knowledge of central aspects of Monte Carlo methods, Markov chains, Gibbs samplers and their possible applications;
|
||

|
||
- Learn about various neural networks and deep learning methods for supervised and unsupervised learning;
|
||
- Learn about about decision trees and random forests
|
||
- Learn about support vector machines and kernel transformations
|
||
- Reduction of data sets, from PCA to clustering, supervised and unsupervided methods
|
||
- Work on numerical projects to illustrate the theory. The projects play a central role and students are expected to know modern programming languages like Python or C++.
|
||
|
||
## Prerequisites
|
||
|
||
Basic knowledge in programming and mathematics, with an emphasis on linear algebra. Knowledge of Python or/and C++ as programming languages is required and experience with Jupiter notebook is recommended. Required courses are the equivalents to the University of Oslo mathematics courses MAT1100, MAT1110, MAT1120 and at least one of the corresponding computing and programming courses INF1000/INF1110 or MAT-INF1100/MAT-INF1100L/BIOS1100/KJM-INF1100.
|
||
|
||
|
||
## The course has two central parts
|
||
|
||
1. Statistical analysis and optimization of data
|
||
2. Machine learning
|
||
|
||
### Statistical analysis and optimization of data
|
||
|
||
The following topics will be covered
|
||
- Basic concepts, expectation values, variance, covariance, correlation functions and errors;
|
||
- Simpler models, binomial distribution, the Poisson distribution, simple and multivariate normal distributions;
|
||
- Central elements of Bayesian statistics and modeling;
|
||
- Central elements from linear algebra
|
||
- Gradient methods for data optimization
|
||
- Monte Carlo methods, Markov chains, Metropolis-Hastings algorithm;
|
||
- Linear methods for regression and classification;
|
||
- Estimation of errors using cross-validation, blocking, bootstrapping and jackknife methods;
|
||
- Practical optimization using Singular-value decomposition and least squares for parameterizing data.
|
||
|
||
|
||
### Machine learning, mainly supervised learning
|
||
|
||
The following topics will be covered
|
||
- Linear Regression and Logistic Regression;
|
||
- Neural networks and deep learning;
|
||
- Decisions trees and nearest neighbor algorithms
|
||
- Support vector machines
|
||
|
||
All the above topics will be supported by examples, hands-on exercises and project work.
|
||
|
||
Computational aspects play a central role and the students are
|
||
expected to work on numerical examples and projects which illustrate
|
||
the theory and methods. Some of the projects can be coordinated with the high-performance programming course IN4200.
|
||
|
||
|
||
|
||
## Practicalities
|
||
|
||
1. Four lectures per week, Fall semester, 10 ECTS;
|
||
2. Four hours of laboratory sessions for work on computational projects;
|
||
3. Three projects which are graded and count 1/3 each of the final grade;
|
||
4. A selected number of weekly assignments;
|
||
6. The course is part of the CS Master of Science program, but is open to other bachelor and Master of Science students at the University of Oslo;
|
||
7. Grading scale: Grades are awarded on a scale from A to F, where A is the best grade and F is a fail;
|
||
8. The course will be offered as a FYS-MAT4155 (Master of Science level) and a FYS-MAT3155 (senior undergraduate) course.
