This video will give you an overview about the course.
MATLAB will show us a desk of contents with all the necessary items for its proper and smooth operation.
In this video, we will start from data collection and import in MATLAB for whatever analysis we are going to do. As well, we will finish our activities by exporting the results.
Many of the functions we have used to import data into MATLAB have a corresponding function that allows us to export data. In this video, we will see those functions.
So far, for data organization, we have mostly used standard arrays that represent useful data structures for storing a large number of objects, but all of the same type, such as a matrix of numbers or characters. However, such arrays cannot be used if you want to memorize both numbers and strings in the same object. This is a problem that can be solved by so-called cell arrays, structure arrays, and more generally all those structures that the MATLAB programming environment provides us.
Before passing our data to machine learning algorithms, we need to give a first look at what we've imported into MATLAB to see if there are any issues. To get started, it's good practice to keep your original data. To do this, every change will be performed on a copy of the dataset.
In the exploratory phase of a study, we try to gather a first set of information needed to derive features that can guide us in choosing the right tools to extract knowledge from the data.
We will begin our visual analysis with an example in which we will draw a simple diagram to extract statistical indicators. It helps us to calculate and plot descriptive statistics with the data.
To introduce the key concepts, we will get started with a simple linear regression example. We just use a spreadsheet that contains the number of vehicles registered in Italy and the population of the different regions.
In this video, we will learn to create a linear regression model.
MATLAB is the language of choice for many researchers and mathematics experts when it comes to machine learning. This video will help beginners build a foundation in machine learning using MATLAB. You'll start by getting your system ready with the MATLAB environment for machine learning and you'll see how to easily interact with the MATLAB workspace. You'll then move on to data cleansing, mining, and analyzing various data types in machine learning and you'll see how to display data values on a plot. Next, you'll learn about the different types of regression technique and how to apply them to your data using the MATLAB functions. You'll understand the basic concepts of neural networks and perform data fitting, pattern recognition, and clustering analysis. Finally, you'll explore feature selection and extraction techniques for dimensionality reduction to improve performance. By the end of the video, you'll have learned to put it all together via real-world use cases covering the major machine learning algorithms and will be comfortable in performing machine learning with MATLAB.
