Description
This course is intended to give the student an overview of Python's machine learning library, sklearn. The course is broken down into seven sections, being:-1. Introduction2. Supervised learning3. Semi-supervised learning4. Unsupervised learning5. Dimensionality reduction6. Feature selection7. Other topicsThe student will receive extensive guidance on how to use sklearn. Sklearn's search engine will be used to research sklearn's many functions, which include:-1. Preprocessing functions2. Classification models3. Regression models4. Semi-supervision models5. Clustering models6. Dimensionality reduction functions7. Feature selection functions8. Metrics functionsIn addition to learning about the numerous and varied types of functions in sklearn, The student will go over the code of twelve Jupyter Notebooks. The subject matter of these notebooks are:-1. Supervised classification problems2. Supervised regression problems3. Semi-supervised classification problems4. Semi-supervised regression problems5. Unsupervised classification problems6. Dimensionality reduction7. Feature selection by selecting the best features 8. Feature selection by selecting a percentage of the best features9. Logistic regression versus decision tree 10. The machine learning life cycleThe student will, using sklearn and other coding, cover the entire machine learning life cycle from the beginning to the end. This will cover:-1. Creating a Jupyter Notebook in Google Colab2. Importing Python libraries into the Jupyter Notebook3. Loading the dataset from either sklearn, openml, or Github4. Cleaning the data by taking care of any null values5. Encoding the data to covert object features to numeric features6. Using visualisation techniques to analyse the data7. Removing any outliers from regression models where necessary8. Removing any feastures that have a high correlation where necessary9. Reducing the dimensionality of a dataset where necessary10. Reducing the features of a dataset where necessary11. Assigning dependent and independent variables12. Splitting the dataset into training and validation sets where necessary13. Selecting the most appropriate model14. making predictions on the model15. Analysing the accuracy of the model by using metric functions
