On May 26, 2021, Ronald van Loon shared his advice on developing a machine learning career in a Simplilearn webinar. Ronald, the CEO of Intelligent World, is recognized as one of the foremost thought leaders in data science and digital transformation. He is a member of Simplilearn's Advisory Board
The AI Career Landscape
AI is getting even more traction lately because of recent innovations that have made headlines, Alexa’s unexpected laughing notwithstanding. But AI has been a sound career choice for a while now because of the growing adoption of the technology across industries and the need for trained professionals to do the jobs created by this growth. However, it is also forecasted that this technology will wipe out over 1.7 million jobs, resulting in about half a million new jobs worldwide. Moreover, AI offers many unique and viable career opportunities. AI is used in almost every industry, from entertainment to transportation, yet we have a massive need for qualified, skilled professionals.
AI and Machine Learning Explained
If you’re new to the field, you might be wondering, just what is Artificial Intelligence then? AI is how we make intelligent machines. It’s software that learns similar to how humans learn, mimicking human learning so it can take over some of our jobs for us and do other jobs better and faster than we humans ever could. Machine learning is a subset of AI, so sometimes when we’re describing AI, we’re describing machine learning, which is the process by which AI learns.
With machine learning, algorithms use a set of training data to enable computers to learn to do something they are not programmed to do. Machine learning provides us with technology to augment our human capabilities.
AI has widespread benefits. Both people and companies benefit from AI. Consumers use AI daily to find their destinations using navigation and ride-sharing apps, as smart home devices or personal assistants, or for streaming services. Businesses can use AI to assess risk and define the opportunity, cut costs, and boost research and innovation.
The Three Main Stages of AI
AI is rapidly evolving, which is one reason why a career in AI offers so much potential. As technology evolves, learning improves. Van Loon described the three stages of AI and machine learning development as follow:
- Stage one is machine learning - Machine learning consists of intelligent systems using algorithms to learn from experience.
- Stage two is machine intelligence - Which is where our current AI technology resides now. In this stage, machines learn from experience based on false algorithms. It is a more evolved form of machine learning, with improved cognitive abilities.
- Stage three is machine consciousness - This is when systems can do self-learning from experience without any external data. Siri is an example of machine consciousness.
What is a Machine Learning Engineer?
To begin, Ronald defined the role of the machine learning engineer as distinct from other data-related roles like data scientist or AI architect.
First, the machine learning engineer assesses, organizes, and monitors data sets that feed machine learning systems. Because these systems learn from whatever data they are given, they need to properly select and condition that data to support the desired learning. Understanding the available data and what types of learning it can support is a foundational step.
Second, the machine learning engineer develops machine learning systems. Knowing the nature of the available data and the intended purpose of the machine learning system, the machine learning engineer chooses the correct technologies and architecture to learn from that data and produce the required inferences and behaviors.
Lastly, the machine learning engineer builds the models that the machine learning system will utilize. These models define how the system interprets the data and learns from it. The model-building process includes testing the models with test data sets to validate that they produce the expected inferences and behaviors.
Machine learning is rapidly spreading throughout business, industry, and government. New technologies increase the power of machine learning continuously, and new applications of machine learning emerge almost daily. Moreover, digital transformation and the acceleration it has caused has multiplied the amount of data organizations must process and reduced the time those organizations have to make decisions. Machine learning systems help organizations react to the flood of data faster and better, and this is why the demand for machine learning engineers is soaring.
According to recruitment site Indeed, average salaries for machine learning engineers in the USA are around $120,000. The number of job openings for machine learning engineers in the USA grew 344% between 2015 and 2018, and the growth continues to be strong.
Next, let’s have a look at what is the machine learning career path of an engineer.
What Does a Machine Learning Engineer Need to Know?
Machine learning engineers need knowledge and skills in several domains:
- Software. Machine learning engineers are responsible for developing and improving software-based systems and creating automation tools to improve the operating efficiency of those systems. They must have strong skills in software architecture and development. Specific software skills include practical familiarity with Python, R, Java, and SQL.
- Data. Machine learning engineers need to understand where to find the useful meaning in data and how to work with large datasets. They need to take raw input data and convert it into clean and accessible datasets for training machine learning models. They also need to know how to manage the databases that store and present the data to the machine learning system. Valuable skills include managing SQL and non-SQL databases and using big data tools like Hadoop.
- Mathematics, statistics, and algorithms. Machine learning engineers need to understand the mathematical and statistical principles that underlie AI and machine learning. They need to be familiar with the algorithms and architectures of AI and machine learning, including deep learning.
- Soft skills. Machine learning engineers work as part of multifunctional teams to support the overall goals of their respective organizations. They need communications skills to take the requirements of the organizations and translate them into specifications for machine learning systems. They need to understand how to organize and manage projects for system implementation, and they need to have leadership and teamwork skills to work effectively with their colleagues and customers.
Subsets of Machine Learning
In addition to the development of machine learning that leads to new capabilities, we have subsets within the domain of machine learning, each of which offers a potential area of specialization for those interested in a career in AI.
Neural NetworksNeural networks are integral for teaching computers to think and learn by classifying information, similar to how we as humans learn. With neural networks, the software can learn to recognize images, for example. Machines can also make predictions and decisions with a high level of accuracy based on data inputs.
Natural Language Processing (NLP)Natural language processing gives machines the ability to understand human language. As this develops, machines will learn to respond in a way a human audience can understand. In the future, this will dramatically change how we interface with all computers.
Deep LearningDeep learning is at the cutting-edge of intelligent automation. It focuses on machine learning tools and deploying them to solve problems by making decisions. With deep learning, data is processed through neural networks, getting closer to how we think as humans. Deep learning can be applied to images, text, and speech to draw conclusions that mimic human decision making.
Industries Currently Using AI
During the webinar, many of the audience questions revolved around companies that are currently using AI, and therefore hiring skilled AI professionals. The answer is, AI is being used in many types of applications across many different industries.
The self-driving car is probably the best-known use of AI. Predictive maintenance is another part of AI, forecasting when maintenance will be needed so it can be done proactively, leading to tremendous cost savings. AI is used in transportation, such as for train scheduling and to help Uber drivers navigate routes. Smart cities use AI to be more energy-efficient, reduce crime, and improve safety.
