A career in machine learning pays well and allows you constantly evolve in the profession. The technology itself is also fascinating and will undoubtedly change the world. That is why more and more people are thinking about joining this field.
What is machine learning?
Machine learning deals with finding algorithms for solving problems. Machine learning engineers (depending on the direction of their work) create algorithms for finding patterns in arrays of data and analyzing/visualizing the information obtained.
Interest in the ML industry is growing year after year. The International Data Corporation predicts that AI and ML spending will be $100 billion by 2025, with the value of the whole industry of around $600 billion.
The whole area of machine learning is developing, specialists related to this area may be needed in different companies, and the important thing is not a diploma or certificate but fundamental knowledge and skills that a person can apply in practice.
Companies and government agencies collect a huge amount of data, but only now has technology started to allow you to work with this information and benefit the development of virtually any area. In addition, computers are now very fast, and libraries are simple enough that even a small team of ML specialists can research productively.
What do you need to know to work with ML?
There are a lot of things that machine learning specialist needs to understand and be able to do:
- Basics: what are data structures, and what are their types (trees, stacks, graphs, multidimensional arrays)? What are search and sort algorithms, dynamic programming, and computer architecture, and what is the operation of the basic concepts of computability and complexity? Theoretical knowledge needs to be able to apply in practice with languages like Python and R.
- Probability theory and statistics: how median and variance are calculated and reflected, what is the essence of Bayes theorem, what are a confidence interval and types of distributions.
High-level professionals should have competencies in natural language processing and computer vision and experience with big data tools like Apache Spark, Hive, Hadoop, MapReduce, HDFS, and various Python/R libraries.
The range of machine learning professions is not limited to ML engineers and also includes:
- Data Scientists. Professionals in data interpretation with programming and mathematical modeling skills. They can design and work with machine learning algorithms and new data models.
- Data Analysts. Professionals who sift through data and try to establish what the information says, what numerical patterns exist, and what decisions can be made based on those findings. They also visualize the data.
- Data Engineers. Professionals whose main job is preparing databases (including assembling disparate data sources into one database and unifying formats).
Each specialization requires specific knowledge, so one programmer is likely to be able to fill only some positions.
Key benefits of AI
One of the key benefits of standing machine learning is the increasing demand for AI professionals across industries. As businesses increasingly integrate AI into their operations, the need for skilled people who can develop, implement, and maintain AI systems. This high demand not only ensures job security but also provides ample opportunities for career growth and further advancement.
AI involves solving complex problems, developing algorithms, and creating systems that can mimic human intelligence. This constant intellectual challenge fosters a dynamic and engaging work environment, making it an ideal choice for those who thrive on innovation.
AI careers also offer the chance to make a positive impact on society. From healthcare to finance and education, AI applications are transforming industries and improving efficiency. Being part of this transformative journey allows professionals to contribute to groundbreaking solutions that address real-world challenges and improve the quality of life for people globally.
Where to start?

The best online course on machine learning for beginners was created by Andrew Ng, an AI expert, Stanford professor, Coursera co-founder, and Google Brain co-founder. After that, we suggest checking out the Deep Learning specialization by the same author.
Books would be helpful, too. For example, «Deep Learning with Python» by François Chollet and «Think Stats: Probability and Statistics for Programmers.»
Keeping the learning vibes alive is key for a successful AI career. Jump into online courses from cool platforms like Coursera or Udacity. The certifications you grab from these places aren’t just pieces of paper – they shout out to the industry that you know your stuff.
Networking is like making buddies for your AI journey. Get into AI conferences, workshops, and meetups to meet the cool cats in the field. Hang out in online forums and communities to catch up on what’s hot and chat with folks who geek out on AI like you do.
Internships and starter gigs are like the training wheels for your AI career. They’re your chance to dive into real projects and turn your bookish knowledge into practical skills. Lots of companies are down to give beginners a shot in the real AI game.
Stay in the learning groove because AI moves at lightning speed. Flip through research papers, catch webinars, and hop into online courses to keep your skills sharp. If you follow these steps and stick to learning and doing cool stuff, you’ll ride the AI wave like a pro.
To develop your competencies in machine learning and get a job, it is not enough to take some online courses, attend professional conferences, and read articles – it’s all about practice. Participate in a competition on the Kaggle platform or try to create your project based on data in the public domain. Even if the project does not develop further, you will have a case to discuss at the interview.
Also, try to join the ML community, come to meetups and lectures, participate in hackathons.
