A graduate, master’s, or doctorate degree in Computer Science is a must to enter the domain of AI and machine learning. Since machine learning and AI jobs entail development of algorithms, problem-solving and analytical skills come in really handy when considering a career in this field. Let’s take a look at a list of skills that will help you build your career in artificial intelligence.
1. Statistical Skills
As an AI professional, you will be expected to have an in-depth understanding of statistics and probability to understand complex algorithms. Today’s AI models, at their most basic forms, depend on finding patterns in large amounts of information. As an architect of these systems, you must be well-versed with the statistical methods used to derive insights from data.
Moreover, you must also be familiar with common AI models, such as Gaussian Mixture Models, Naïve Bayes, Hidden Markov Models, etc. These principles are based on complex statistical proofs and theorems, requiring AI developers to have an in-depth knowledge of the subject to understand their workings. Thus, detailed knowledge of statistics helps programmers become better AI professionals.
2. Mathematical Skills and Probability
Anyone wanting to pursue their career in artificial intelligence or machine learning is expected to be an expert in applied mathematics. Apart from statistics, AI as a field also features many mathematical concepts to create artificial intelligence. One of the most prominent mathematical principles in use is probability.
Probability determines a variety of outcomes in AI, with a deeper understanding of the subject being integral to creating AI models. Apart from these, AI professionals also need to have excellent analytical and problem-solving skills that come from developing one’s mathematical skills.
3. Programming Skills
Math is just one of the skillsets that aspiring AI and ML professionals are expected to have. This is only one half the requirement, the other half is one’s expertise in programming languages, such as Java, C++, Python, and R.
While C++ helps engineers increase the speed of their coding process, Python will help them understand and create complex algorithms. Python is also the go-to choice for ML developers, and also offers various libraries and frameworks to ease the process of creating an AI model. Similarly, R and Java help professionals understand stats and implement mappers, respectively. They are important considering the role of visualization in explaining AI.
4. Advanced Signal Processing Techniques
Feature extraction is an integral characteristic of machine learning. To understand the next feature and how to implement it is an important part of managing a model’s deployment. To this end, AI and ML engineers are expected to be familiar with a variety of advanced signal processing techniques.
Digital signal processing has also seen a revolution of sorts with the rise of AI, enabling techniques such as layered signal representations, nonlinear function approximation, and nonlinear signal prediction. This means that aspirants will need to have a working knowledge of algorithms like curvelets, bandlets, and shearlets to master feature extraction.
5. Distributed Computing
Almost all the AI job roles require professionals to deal with complex and large datasets, which are difficult to process using a single machine. These datasets have to be distributed equally across an entire cluster, the reason why all AI and ML professionals are expected to be experts in distributed computing.
This includes expertise in applications, such as MongoDB, along with experience in creating and operating cloud environments. With the rise of ML-focused cloud services, companies are looking for individuals who have experience working with them.
Apart from these skills, AI and ML professionals should also have a good command over Unix tools and possess data modeling and evaluation skills. This is due to the fact that Unix is one of the most common working environments for AI/ML professionals and the base for many cloud services.
There are five major roles that you can choose from, on your AI and ML career path. Let’s take a look at each one in detail.
Machine learning engineers are programmers who program the machines to perform specific tasks. They are responsible for managing as well as building machine learning platforms. This role is ideal for professionals who have an educational background in programming and engineering, as most of the learned skills will enable easier role transitions.
Machine learning engineers are also required to develop their skills in various programming languages, such as Python, Java, and Scala. ML engineers should also have a working knowledge of how to manage large amounts of data using utilities such as R and SQL. Not only should they be able to apply predictive models, but they should also be able to leverage big data best practices while dealing with enormous datasets.
Aspiring ML engineers will benefit from a few years of experience in agile development practices and leading development tools, like IntelliJ and Eclipse. A master’s degree or a doctoral degree in computer science or mathematics along with strong computer programming and analytical skills will further up your chances of getting hired.
Data scientists are responsible for the collection, analyzing, and interpretation of large and complex datasets with the help of predictive analytics and machine learning. They may also be required to implement new machine learning models to help an organization make more timely and effective decisions.
Data scientists play a very important role in developing algorithms that allow data to be collected and cleaned for analysis.
