Machine learning is becoming more and more similar to the way humans learn. Although we still don’t have artificial intelligence that is advanced enough to think abstractly, feel emotions, or be creative, machines are now able to learn singular tasks.
Some examples of how ML is used today include image recognition, speech recognition, Google maps, Google’s algorithm, online ad recommendations, health care machines, and self-driving cars.
If you’re researching how to learn machine learning, read on for a full breakdown of the field, and the best courses and resources to learn machine learning.
What Is Machine Learning?
Machine learning, or ML, combines computer science and statistics to enable a device to learn a task rather than being programmed to do so. Machine learning algorithms use data to make decisions and predictions.
ML training is all about determining how we can use technology to help us. As classification algorithms get stronger, it is becoming easier for humans to compare data and gain valuable insight.
For example, maybe you are researching ants and want to distinguish between different species of ants. So, you can provide the machine with training data on the mass and length of the ants you have already recorded, and as the machine learns, it will be able to predict the category of any new species you find.
Furthermore, as technology progresses and machine learning improves, artificial intelligence will get stronger. Machines will become more capable of assessing situations, accumulating data, and thinking cognitively to make decisions.
What Is Machine Learning Used For?
What if humans could train machines to learn from their past as we do, but at a much faster speed? Modern machine learning is based on algorithms, which are a series of calculations carried out by a computer. Below are some examples of machine learning:
- Facebook. When you post a picture on social media, you may see a facial recognition box appear, suggesting friends for you to tag in the photo. This is a facial recognition algorithm created by “Deepface” researchers at Facebook. The job of these researchers is to discover ways to add deep learning to the Facebook algorithm to make it easy for you to tag people in photos.
- Uber. Uber uses machine learning to create a better user experience within its app. ML is used to estimate arrival times and predict where you may want to go based on your current location.
- Google Translate. Using hundreds of thousands of translated texts, Google translate is helping people break through language barriers. Although the algorithm is not always entirely accurate, it is an extremely helpful tool for travelers.
- KUKA. This German manufacturer is using machine learning in its robotic arms made for factory automation. These innovative arms can grab and move objects thanks to data analytics and machine learning.
- Amazon Ads. The use of algorithms means that when you click on an item on Amazo,n but decide not to purchase it, you will see other advertisements on different websites for similar items. Similarly, ML will also recommend products or services based on data from your search history.
Types of Machine Learning Careers
Are you wondering what potential careers you can pursue after taking a machine learning class? In today’s tech-centered world, you will have plenty of options.
Machine Learning Researcher
For those interested in advancing our knowledge of ML, research might be an ideal role. Researchers develop theories and test them through trial and error to create new algorithms and data sets that will further machines’ capabilities.
Machine Learning Engineer
Engineers integrate machine learning systems to create an end-to-end machine experience. They create programs and algorithms that make it possible for machines to take actions without being directed to by humans. Foundational knowledge in software engineering is a requirement for a role like an ML engineer.
Machine Learning Scientist
ML scientists focus on modeling, measuring, and debugging. They build models and create training data, based on the learning algorithms that are used for certain tasks. They also have knowledge of programming languages such as Python.
Data science uses scientific methods and algorithms to extract knowledge from data. Data science is related to machine learning, data mining, and big data.
Machine Learning Architect
The architect creates machine learning solutions to real-world problems. The processes involved in ML architecture are data acquisition, data processing, model engineering, execution, and the deployment of a creation.
Learning Machine Learning
However, there are many ways to build up your ML skills, such as attending a coding bootcamp, taking specific machine learning classes, and creating your own machine learning projects to fill your portfolio.
Employers may advertise a role as requiring a master’s degree, but they usually value experience over a degree, so don’t be discouraged.
How Long Does It Take to Learn Machine Learning?
This depends on the individual and their ability to learn the related skills, combined with your preferred learning path. It is impossible to put a time frame on learning ML as it involves an understanding of mathematics, coding, data science, and a separate set of ML skills.
However, if you already know how to code and have strong mathematics knowledge, you can potentially complete a course in ML in as little as two days.
How to Learn Machine Learning: Step-by-Step
Are you unsure of how to begin your machine learning journey? Allow us to break it down for you in a step-by-step guide below.
- Learn Calculus. The first step is to learn multivariable calculus. This is usually done either in your second year of undergraduate studies or through an accredited certification course.
- Learn Linear Algebra. Although these first two are not 100 percent necessary, they will provide you a good foundation for the rest of your career. Taking a linear algebra course at college or through an online certification course will be great for your resume.
- Machine Learning Training. Next, you should get some training in machine learning. In the course, you can expect to be taught supervised learning, unsupervised learning, semi-supervised learning, reinforcement learning, deep learning, decision trees, support vector machines, and linear regression.
- Create Personal Projects. Now, you can begin a personal project in machine learning and data science. You can start by crafting simple neural networks, and later move on to deep neural networks. Pursue the type of problems that you want to solve and have fun working on projects that will also boost your skills.
