In this course the student will learn how to use Google Colab, Python's machine learning library, sklearn, and Python numerical library, numpy, to create datasets and use them in machine learning enterprises.
The datasets will be created in sklearn and numpy, and are comprised of classifications and regressions, being 24 in total.
When the datasets have been created, machine learning techniques will be employed to make predictions on the labels. In addition, the concepts of supervised and unsupervised learning will be discussed. Although most of the examples will be of supervised learning, clustering will be brushed upon.
Some of the datasets introduce noise into the system, and this will decrease accuracy of predictions. The student will be shown how to tune the parameters of the appropriate datasets to reduce noise and thereby improve accuracy of the predictions. This proves that noise has an inverse relationship to accuracy of the model.
Some of the datasets will have outliers, so methods for reducing outliers in the dataset will also be discussed. When the outliers are removed, accuracy of the predictions are also likely to be increased. This proves that outliers have an inverse relationship to accuracy of the model.
The student will be taken through the following steps to create a dataset and write a program to make predictions on the labels:-
1. Import libraries.
2. Create dataset.
3. Plot a graph of the dataset so it can be seen in the computer's memory.
4. Analyse the label.
5. Remove outliers if necessary.
6. Normalise or standardise the independent variable if necessary.
7. Split the dataframe into training and validation sets.
8. Select the model.
9. Train and fit the training set into the model.
10. Make predictions on the validation set.
11. Check accuracy and / or error of the predictions.
12. Compare the predictions against the actual values.
13. Plot the predictions on a graph.
