An introduction to machine learning in R focusing on classification (supervised learning)
![Kurs-banner](/tjenester/it/kurs/alle/dht/ressurser/banner.webp)
Frequency: Twice a year
Time: 2 x 3 hours
Language: English or Norwegian
Type of course: In person
Target audience:
UiO reseachers and students who want to get started with machine learning in R.
A video (approximately 25 minutes) has been prepared that might be useful for those that are completely new to machine learning, with example use-cases in research.
Prerequisites:
It is an advantage but not necessary that you are accustomed to writing code in R. Basic knowledge of descriptive statistics and tidyverse is a plus.
Contents:
- Exploratory data analysis
- Binary classification
- Feature importance
- Multiclass classification
- Cross-validation
- Additional topics
- Preprocessing data with "recipe"
- Building and evaluating multiple models
simultaneously - Statistically comparing models
- Hyperparamater tuning
- Predicting a continuous variable
Briefly about the course:
The focus will be on building and evaluating machine learning models in R rather than an in-depth breakdown of specific algorithms. We will be building models to distinguish between different categories of text based on linguistic features (including number of nouns, adjectives, etc.) using XGBoost.
