Design patterns offer a clear structure to design more efficient and maintainable systems for AI and LLM engineers in Python.
Design patterns work in three main categories - Creational Patterns, Structural Patterns and Behavioral Patterns.
Singleton Pattern in Python is used to create a class with only one instance and provide access to that instance globally.
Factory pattern in Python delegates the creation of objects to subclasses or dedicated factory methods for creating different types of models, data loaders or pipelines based on the specific context.
Builder Pattern separates the construction of a complex object from its representation. It is useful for building pipelines, managing configurations, and readable objects that have many parameters.
The strategy pattern allows switching between different strategies (inference or data processing) depending on the requirements.
The observer pattern establishes a one-to-many relationship between objects in the real-time monitoring of events, data synchronization and metrics.
Design patterns have unique characteristics in AI engineering as they involve dynamic workflows rather than just managing a database and user session.
When implementing design patterns in AI engineering, one should consider the scalability and performance implications.
Using best practices such as not over-engineering, documentation and testing can help improve code organization and make it more maintainable.
