If you plan to use the OpenAI API for chatbot development, take a look at our course on Working with the OpenAI API.

C++

C++ provides the ability to execute high-level applications with a relatively low computational cost, making it suitable for machine learning and neural network computation.

Libraries like Shark and mlpack are designed for machine learning in C++. AI use cases include computer vision tasks, robotics, and gaming. Check out our tutorial on Llama.cpp to learn how C++ is used with the LLaMa LLM.

2. Data modeling & engineering

Data is the foundation of AI, and AI engineers need to have a deep understanding of data modeling and engineering.

They should know how to acquire, clean, and transform data into a suitable format for analysis. Knowledge of SQL and NoSQL databases is essential for querying and managing large datasets.

Tools such as Apache Spark, Hadoop, and AWS S3 are also commonly used for data processing in AI projects.

3. Big data analysis

AI engineers should be able to analyze large sets of data and extract meaningful insights from them. This involves using big data tools such as SparkSQL, Apache Flink, and Google Cloud Platform to query and manipulate large datasets.

Our big data fundamentals with PySpark course covers many of the principles behind big data analysis, making it a perfect starting point for you to learn.

4. Machine learning models

Knowledge of machine learning models and algorithms is a must for AI engineers.

This includes understanding supervised and unsupervised learning techniques, as well as deep learning algorithms such as convolutional neural networks (CNNs) and recurrent neural networks (RNNs).

AI engineers should also know how to evaluate the performance of these models using metrics like

  • Accuracy
  • Precision
  • Recall
  • Root-mean-square deviation (RMSE),
  • Mean absolute error (MAE)
  • F1 score

Our Machine Learning Fundamentals with Python skill track can help you learn many of the basics of machine learning.

5. AI and ML services

AI engineers should also be familiar with cloud-based AI and machine learning services offered by major providers such as AWS, Azure, and Google Cloud Platform. These services provide pre-built models, APIs, and tools for developing intelligent applications without the need for extensive coding. Check out out AWS, Azure and GCP Service Comparison cheat sheet for more details. 

6. AI Deployment & DevOps

Deploying AI applications involves collaborating with DevOps teams to ensure smooth integration and deployment.

AI engineers should know how to use tools such as Docker and Kubernetes for containerization, configuration management, and orchestrating deployments.

They are also responsible for monitoring and maintaining the performance of AI systems post-deployment.

Our Introduction to Docker course provides a good foundation to start with, and you can find out more about Docker certification in a separate article.

7. AI security

Understanding and implementing strong data security and privacy measures is crucial for any AI engineer, as AI applications bring new security vulnerabilities.

As an AI engineer, it is your responsibility to ensure the confidentiality, integrity, and availability of the data you handle.

This involves understanding regulations related to data protection, such as the General Data Protection Regulation (GDPR), and implementing secure AI frameworks that comply with these regulations.

Additionally, AI engineers must be knowledgeable about various encryption methods, secure AI model development practices, and be prepared to handle potential security attacks or breaches.

Some techniques used by AI engineers include:
