• Data transformation: Prepare data through normalization and scaling
• Model explainability: Build interpretable models with techniques like LIME and SHAP
• Scalability optimization: Design your model to handle growing datasets

3) Machine learning models and evaluation metrics

Understanding evaluation metrics is crucial for measuring AI model performance, making it one of the most essential AI engineer skills:

Classification metrics:

• Accuracy: Ratio of correct predictions to total predictions
• Precision: Proportion of correctly identified positives
• Recall: Proportion of actual positives correctly identified
• F1 Score: Harmonic mean of precision and recall

Regression metrics:

• Mean Absolute Error (MAE): Average distance between predicted and actual values
• Mean Squared Error (MSE): Average of squared differences between predictions and actual values
• Root Mean Squared Error (RMSE): Square root of MSE
• R² Score: Proportion of variance explained by the model

4) Big data tools and platforms

AI engineers need familiarity with tools that handle massive datasets, making this one of the most important AI engineer skills:

• Hadoop provides a distributed file system for storing and processing large datasets across computer nodes, making it ideal for high-scale training.
• Apache Spark offers fast cluster computing for big data with high-level APIs in multiple languages. It processes huge amounts of data quickly and works with various programming languages.
• NoSQL databases like MongoDB and Cassandra store vast amounts of unstructured data with more flexibility than traditional SQL databases.

5) AI deployment and DevOps tools

AI DevOps tools streamline automation across the entire development lifecycle:

• CI/CD automation: Tools help automate building, testing, and deploying code that passes appropriate tests
