Best Machine Learning Courses
What Is Machine Learning?
Machine learning is a form of data analysis. It uses artificial intelligence to create programs and algorithms which learn from data to predict future patterns and trends.
Over time, the program becomes more familiar with the data, thereby increasing the accuracy of its predictions. Using this process, it is essentially learning by itself or with very little human interaction.
There are essentially three main types of machine learning algorithms:
- Unsupervised – Uses clusters of data to analyze complex information
- Supervised – Identifies patterns and data points to make predictions
- Reinforcement – Actions can be taken depending on various data points. Some of these actions will be automated, while others will require manual input.
We experience the effects of machine learning in our everyday lives without really noticing it. Just a few examples of machine learning algorithms are:
Fraud detection within banking – Your bank will notice if there is unusual behavior on your account and potentially flag a fraud warning. This is thanks to machine learning algorithms that analyze your typical behavior patterns.
Social media – Algorithms are key to being noticed on social media. The way that hashtags and content are analyzed will decide how prominently your posts appear and the level of reach that you have.
Recommendations on your streaming service – By looking at the genres of programming that you most frequently watch, algorithms can suggest other shows which you might enjoy.
Spam filters – The programming which decides whether the emails going into your inbox are spam or genuine is a form of machine learning technology.
Why Study Machine Learning?
The ability to create software that performs machine learning functions is becoming more and more vital in today’s world.
Artificial intelligence is a rapidly growing area of software development and as such, the demand for developers is constantly increasing.
Data analysis and development are core areas within most areas of business, and this demand is only likely to increase in the future.
To study machine learning, it is generally recommended that you have some knowledge of programming, as well as calculus, algebra and statistics.
This is because it is considered an advanced discipline within programming and data analysis.
However, it is not required for all courses and some can be taken alongside refresher courses for the areas in which you may not have as much experience.
How Long Does It Take to Study Machine Learning?
The length of time it takes to complete your machine learning course will vary hugely depending on which course you take.
Some provide an introduction to the world of machine learning and may only take a few hours to complete.
Others may involve more detailed information, but be self-paced, meaning that you can complete them as quickly or as slowly as you want. There are also courses that follow structured timings and may take up to two years.
It is important to note that once you have finished your machine learning course, there will be opportunities in the future to carry on learning.
As this area of industry is developing so quickly, there are always new things to learn. Much of this will be on-the-job learning.
How to Choose a Machine Learning Course
With so many options available, it can be hard to know which course will suit you best. When deciding on a course, there are a few things to consider:
What Do You Want to Learn?
Machine learning and data analysis are hugely varied areas of industry. It is a good idea to consider which areas you would like to work in as this will help to guide your decision-making process on courses.
It may be that you only need basic knowledge, in which case an introductory course could be best. If you are considering specializing within a specific area, then it is always best to find a course that covers your chosen specialization.
Is a Free Course Suitable for Your Needs?
There are free courses available that can teach you the basics of machine learning.
However, if you are looking to begin a career in this area, it is important to make sure that any course you take will be recognized by employers.
If your preferred free course isn’t recognized, it may be worth considering paying for one that is.
How Long Can You Study For?
If you are considering taking a machine learning course alongside your job, you will have less time available compared with someone who can study full-time.
It is always best to choose a course that fits within the time you have available.
Choosing a course that will leave you overstretched can lead to poor performance and you may not be able to complete the course to the best of your ability.
Do You Have Experience in Math, Programming or Data Analysis?
A large proportion of machine learning and data analysis is math and programming. If you already have experience within these areas, then you may be able to jump straight into a more specialized course.
If there are areas of your knowledge that are weaker, it may be worth considering an introductory machine learning course alongside a refresher course that covers your weakest areas.
If you don’t have experience in math, programming or data analysis, you should consider courses in these areas before beginning a machine learning course.
