AI Engineering 101: A Brief Guide to Intelligent Systems

Written By Ryan Loftus | May 10, 2023

Artificial intelligence is rapidly advancing and becoming more prevalent in our daily lives. From chatbots to autonomous vehicles, AI is changing the way we interact with technology. 

But creating AI-powered systems is not a simple task. It requires a specialized skill set to build AI platforms. 

That’s where AI engineering comes in. 

Defining AI Engineering

AI engineering is the process of designing and developing intelligent systems and applications that can learn and adapt from data. AI engineers use various techniques such as machine learning, deep learning, natural language processing, and reinforcement learning to build intelligent systems that can perform complex tasks, such as image recognition, speech recognition, text analysis, and decision-making.

Machine Learning vs AI Engineering

You might be wondering, “Wait, isn’t that just machine learning?” Fair question. Because AI is an evolving field, the exact definitions of and relationship between the machine learning and AI engineering disciplines can be confusing.

Generally speaking, machine learning and AI engineering are two related but distinct fields within the broader field of artificial intelligence. You can also think of machine learning as an important tool used by AI engineers to build intelligent systems, making it one part of the broader field of AI engineering.

Machine learning is a subfield of AI that focuses on developing algorithms that can learn from and make predictions or decisions on data without being explicitly programmed to do so. In other words, it is a set of techniques that enable machines to learn from data and improve their performance on specific tasks over time. Machine learning techniques include supervised learning, unsupervised learning, reinforcement learning, and deep learning.

AI engineering, on the other hand, is the broader field that encompasses the development, deployment, and maintenance of AI systems. It involves applying the principles of software engineering to build robust, scalable, and maintainable AI systems. AI engineering includes designing and implementing AI models, deploying them in production environments, and managing the data infrastructure needed to support the models. It also involves ensuring that the AI system is secure, reliable, and efficient.

In essence, machine learning is a subfield of AI that focuses on the development of algorithms that enable machines to learn from data, while AI engineering is the application of software engineering principles to build and deploy AI systems. 

How AI Engineering Works

The process of AI engineering typically involves the following stages:

Problem identification: The purpose of any AI model is to solve a business or consumer problem. To develop a successful AI model, engineers start by identifying the exact pain point the AI will solve. For example, many knowledge workers have trouble keeping up with tight production schedules. Conversational AI models like ChatGPT solve this problem by automating labor intensive tasks like coding, writing, and research.

Data collection: AI engineering begins with the collection of relevant data from various sources. The data can be in different formats such as text, images, audio, or video. The quality of the data is crucial as it affects the accuracy of the AI-powered system.

Data preprocessing: The collected data needs to be cleaned and preprocessed to remove any noise or inconsistencies. The data is then transformed into a format that can be used for training and building AI models.

Algorithm Development: AI engineers use various machine learning algorithms such as regression, clustering, classification, and neural networks to build intelligent systems. The choice of algorithm depends on the nature of the problem and the type of data being used.

Model Training: Once the algorithm is selected, the next stage involves training the model using the preprocessed data. The model is trained using various optimization techniques to improve its accuracy and performance.

Model Evaluation: After the model is trained, it needs to be evaluated to ensure that it performs well on new data. AI engineers use various evaluation metrics such as precision, recall, and F1 score to assess the performance of the model.

Deployment: The final stage of AI engineering involves deploying the model in a production environment. The model needs to be integrated with other systems and tested to ensure that it works correctly.

AI Engineering Skills

AI engineering is a multidisciplinary field that requires expertise in various areas such as computer science, mathematics, statistics, and domain knowledge. Here are some of the essential skills required to become an AI engineer.

Programming

AI engineers need to have a good understanding of programming languages such as Python, R, and Java, as well as machine learning libraries like TensorFlow and PyTorch.

Mathematics and Statistics

A strong foundation in mathematics and statistics is essential for AI engineering. AI engineers need to be proficient in calculus, linear algebra, probability, and statistics.

Machine Learning

AI engineers need to have a deep understanding of machine learning algorithms and techniques such as deep learning, supervised and unsupervised learning, reinforcement learning, and neural networks.

Data Analysis and Management

AI engineers need to be skilled in data analysis and management, including data cleansing, pre-processing, feature extraction, and data visualization.

Problem-Solving Skills

AI engineers must be adept at problem-solving and troubleshooting. They need to be able to analyze complex problems, identify potential solutions, and test and implement the best approach.

Communication Skills

AI engineers need to be able to communicate technical concepts and ideas to both technical and non-technical stakeholders.

Creativity

AI engineers must be creative and have a strong imagination to come up with innovative solutions to complex problems.

Domain Knowledge

AI engineers must have domain knowledge in the area they are working on. For example, a healthcare AI engineer would have knowledge of healthcare processes and regulations.

Continuous Improvement

AI is a fast-evolving field, so AI engineers need to be committed to continuous learning to keep up with new technologies and techniques.

Collaboration Skills

AI engineering is often a team effort, so AI engineers need to be able to work collaboratively with other team members, such as data scientists, product managers, and business stakeholders.

Conclusion

AI engineering is an exciting field that is rapidly evolving and has immense potential to transform various industries. It requires a multidisciplinary skill set, and AI engineers should be proficient in programming, machine learning, data management, deep learning, and deployment. With the increasing demand for AI-powered systems, AI engineering is set to become one of the world’s most sought-after skills.
