AI is one of the most popular things in the tech industry. Like data engineering, AI engineering has become popular due to this increasing demand for AI products.

But to be an AI engineer, what tools must you know? This list, which includes AI tools, might have been expanding because of increasing popularity, but you must keep updated and gain skills about these tools.

In this article, we will explore these tools together, but first, let’s focus on AI Engineering; let’s start!

 

What is an AI Engineer?

 

An AI engineer is a person who builds, maintains, and optimizes AI systems or applications. Such practices require experts who integrate software development with machine learning to build intelligent systems designed to perform human-like tasks.

They design predictive models and develop autonomous systems, so their knowledge includes not just theoretical knowledge but practical skills that can be applied to real-world problems.

Of course, to do that, they need to know how to program systems, which requires programming knowledge.

 

Programming Knowledge

 

Strong programming knowledge is a must for an AI engineer to shine. That’s why it is important to excel at a few key languages.

 

Python

Python has dynamic libraries, such as TensorFlow and PyTorch, that are great for AI model training. These libraries have active communities that keep them updated.

This high-level, general-purpose programming that allows freedom for rapid prototyping and fast iteration over the codes is what makes Python a top choice amongst AI engineers.

First, here are the top 30 Python interview questions and answers.

 

R

Another important language is R, especially in statistical analysis and data visualization. It has strong data-handling capabilities and is used in academia and research. R is a tool for heavy statistical tasks and graphics requirements.

You might see many arguments between R and Python when people discuss finding the best programming language for data science. Data Science might be a different field. However, to become an AI engineer, you must do many tasks that a Data Scientist does.

That’s why you might need to find an answer to this old debate too: which is better, R or Python? To see the comparison, check out this one.

 

Java

Java has been used to build large systems and applications. It is not as popular for AI-specific tasks but is important in deploying AI solutions on existing enterprise systems. Java’s power and scalability make it a useful weapon for an AI engineer.

 

SQL

You cannot manage databases without SQL. As an AI engineer, working with relational databases will be most of your work because it involves dealing with and cleaning large datasets.

This is where SQL comes in to help you extract, manipulate, and analyze this data quickly. Doing so helps provide clean, thinned-out structured knowledge that you can forward to your models.

Here is the ultimate guide to the SQL Questions you must prepare.

 

Machine Learning

Machine learning might be the core part of this operation. But before learning machine learning, you need to know about math, statistics, and linear algebra.

 

Math

Understanding machine learning methods depends on a strong mathematical foundation. Important sections cover probability theory and calculus. While probability theory clarifies models like Bayesian networks, calculus supports optimization methods.

Check out this one to practice your knowledge of Math with Python and learn more about coding libraries used in Math.

 

Statistics

Statistics are essential for interpreting data and verifying models. Hypothesis testing, regression, and distribution are the foundations of a statistical study. Knowing these lets you assess model performance and make data-driven decisions.

You can start learning from commonly used statistical tests in Data Science or basic types of statistical tests in Data Science. As you know, you should know the same concepts in both data science and AI engineering. You can check more statistical articles from here.

 

Linear Algebra

Linear algebra is the language of machine learning. It is applied in methods using vectors and matrices, which are basic in data representation and transformations.

Understanding algorithms such as PCA (Principal Component Analysis) and SVD (Singular Value Decomposition) depends on a knowledge of key ideas such as matrix multiplication, eigenvalues, and eigenvectors.

Here is the best video series from 3Blue1Brown, where you can understand linear algebra completely.

 

Big Data

 

AI Solutions rely on the AI scene, which big data supports. Specifically, it talks about the terabytes of data generated every day. Artificial intelligence designers need to handle this data appropriately and effectively. The below examples showcase big data services.

 

Hadoop

Hadoop is an open-source software framework for storing and processing large datasets in a distributed file system across computer nodes. It scales to run on thousands of servers, offering local computation and storage, making it ideal for high-scale training.

This architecture has capabilities that allow for efficient handling of big data and enable it to be reliable and scalable.

 

Spark

Apache Spark is a fast and general-purpose cluster computing system for big data. It provides high-level APIs in Java, Scala, Python, and R and an optimized engine that supports general execution graphs. Benefits are;

  • Good Performance
  • Easy to use ( Spark) 
  • Capable of processing huge amounts of data at lightning speed and compatible with various programming languages

It is a powerful weapon in the hands of an AI engineer. If you want to know more about PySpark, a Python Apache Spark interface, check out “What Is PySpark?”.

 

NoSQL Databases

They are designed to store and process vast masses of unstructured data, called NoSQL databases—e.g., MongoDB or Cassandra. Unlike traditional SQL’s, NoSQL databases are scaleable and flexible, so you can store data more efficiently, fitting into complex data structures for AI.

This, in turn, allows AI engineers to store and better use large datasets, which is necessary to produce powerful prediction models (machine learning) and decision-making that requires fast data processing speed.
