Data Scientist and AI Engineer

Introduction:

In this review, from Isaac Ke, a former data scientist now working as an AI engineer at IBM, discusses the differences between data scientists and AI engineers, with a special focus on generative AI engineering. He investigates four primary areas where their roles diverge and comments on the changing landscape of the industry brought about by generative AI.

Data Scientist vs AI Engineer: Unveiling the Data with Examples

Both data scientists and AI engineers are rockstars in the world of AI, but their approaches differ. Let’s see how their skills play out in real-world scenarios:

The Data Scientist: A Recommendation Engine Guru

Imagine you’re a data scientist working for a music streaming service. You’re tasked with improving user recommendations.

• Data Acquisition: You collaborate with engineers to access user listening history, demographics, and popular playlists.
• Data Wrangling: The data might be messy, with missing values or inconsistent formats. You clean and organize it for analysis.
• Exploratory Analysis: You use statistical methods to identify listening patterns – what genres users listen to together, or how listening habits differ by age.
• Model Building: You develop a machine learning model that analyzes user data and recommends songs they might enjoy based on their listening habits and similar users.
• Communication: You present your findings to the product team, explaining how the model works and the potential impact on user engagement.

The AI Engineer: Building the Recommendation Engine

The AI engineer takes your insights and builds a real-world system:

• Designing and Developing: They translate your recommendation model into code, using frameworks like TensorFlow or PyTorch.
• Software Engineering Skills: They write efficient code to ensure the system can handle millions of users and song recommendations.
• Deployment and Integration: They integrate the recommendation system into the music streaming app, making it accessible to users.
• Scalability and Efficiency: They monitor the system’s performance and optimize it for speed and accuracy as the user base grows.

Collaboration is Key

The data scientist provides the “why” and “what” behind the recommendations, while the AI engineer tackles the “how.” They work together to ensure the final system delivers a valuable user experience.

Another Example: Fraud Detection

• Data Scientist: Analyzes past fraud cases, identifying patterns in transaction behavior that might indicate fraudulent activity.
• AI Engineer: Develops a machine learning model that flags suspicious transactions in real-time, protecting users from financial harm.
