| ===== Objectives ===== | ===== Objectives ===== | ||
| - | * Understand basic concepts of machine learning | + | * TODO |
| - | * Remember examples of real-world problems that can be solved with machine learning | + | |
| - | * Learn the most common performance evaluation metrics for machine learning models | + | |
| - | * Analyse the behaviour of typical machine learning algorithms using the most popular techniques | + | |
| - | * Be able to compare multiple machine learning models | + | |
| - | ===== Exercises ===== | + | ===== Resources ===== |
| - | The exercises will be solved in Python, using various popular libraries that are usually integrated in machine learning projects: | + | TODO |
| - | * [[https://scikit-learn.org/stable/documentation.html|Scikit-Learn]]: fast model development, performance metrics, pipelines, dataset splitting | + | ===== Tasks ===== |
| - | * [[https://pandas.pydata.org/pandas-docs/stable/|Pandas]]: data frames, csv parser, data analysis | + | |

| - | All tasks are tutorial based and every exercise will be associated with at least one "**TODO**" within the code. Those tasks can be found in the //exercises// package, but our recommendation is to follow the entire skeleton code for a better understanding of the concepts presented in this laboratory class. Each functionality is properly documented and for some exercises, there are also hints placed in the code. | + | ==== Google Colab Notebook ==== |

| - | Because the various **tasks** and **exercises** are **spread throughout the laboratory text**, they are marked with a ⚠️ emoji. Make sure you look for this emoji so that you don't miss any of them! | + | |

| - | ==== ⚠️ [10p] Task 5.B ==== | ||
| - | Fetch the **centres of the clusters** (the model should already have them ready for you :-)) and **plot** them together with a **colourful 2D representation** of the data groups. Your plot should look similar to the one below: | ||
| - | |||
| - | {{ :ep:labs:22._clustering_plot.png?600 |}} | ||
| - | |||
| - | You can also play around with the **standard deviation** of the generated blobs and observe the different outcomes of the clustering algorithm: | ||
| - | |||
| - | <code> | ||
| - | CLUSTERS_STD = 2 | ||
| - | </code> | ||
| - | |||
| - | You should be able to discuss these observations with the assistant. | ||
| - | |||
| - | <note> | ||
| - | **HINT: **The **plotting code** is very similar to the one found in the skeleton. You can also [[https://lmgtfy.com/?q=plot+k+means+clusters+python|Google]] it out. ;-) | ||
| - | </note> | ||
| - | |||
| - | ⚠️⚠️ **NON-DEMO TASK** | ||
| - | |||
| - | Look at the hint above and solve the tasks marked with **TODO - TASK B**. Make **at least 3** changes to the standard deviation. That means that **3 plots should be generated**. Save each plot **in a separate file**. | ||
