2. Building Applications with FastAPI

Learn FastAPI for API Development

FastAPI is a modern framework for building APIs with Python. It’s fast and easy to use, making it ideal for deploying AI models.

Key Concepts to Explore:

• Installation and Basics: Get started with FastAPI by installing it using pip.
• Creating APIs: Learn how to create RESTful APIs for your machine learning models.
• Integrating with ML Models: Deploy a simple text generation model using FastAPI.

from fastapi import FastAPI

app = FastAPI()

@app.get("/generate")
def generate_text(prompt: str):
    # Call your generative AI model here to create text
    return {"generated_text": "Sample text based on prompt"}

Recommended Resource

• FastAPI Official Documentation for comprehensive details and examples.

3. Exploring LangChain for LLMs

Introduction to LangChain

LangChain is a framework that simplifies working with large language models (LLMs). It integrates various components to streamline the chaining of prompts and outputs.

Key Topics to Cover:

• Connecting LLMs: Understand how to link together different models and tools.
• Pipeline Creation: Build custom pipelines for generating responses and processing data.

Example Scenario

Create an application that receives user queries and generates relevant responses using an LLM through LangChain.

from langchain import LLM

llm = LLM("your_model_api_endpoint")

response = llm.generate("What is Generative AI?")
print(response)

4. Vector Databases and Fine-Tuning

Utilize Vector Databases for AI

Explore vector databases like Pinecone or Weaviate to store and retrieve embeddings efficiently.

Key Concepts:

• Vectorization Techniques: Understand techniques for translating data into vector forms.
• Querying: Learn how to perform similarity searches.

Fine-Tuning Models

Understand how to fine-tune pre-trained models to better suit your application needs. This involves preparing your dataset and applying techniques to enhance the model's performance.

5. Deep Dive into Prompt Engineering

Mastering Prompt Engineering

Prompt engineering is crucial for effective interactions with LLMs. The way you phrase prompts can significantly affect the quality of generated outputs.

Practice Strategies:

• Experiment with various prompt formulations.
• Analyze output differences based on minor changes in phrasing.

Example of Prompt Structuring

An effective prompt could be structured as follows:

prompt = "Generate a creative story about a lost city under the sea."

6. Understanding AI Agents & Autonomous Systems

Explore AI Agents

Learn how to design agents that can autonomously perform tasks by integrating multiple AI capabilities.

Core Topics to Understand:

• Decision Making: How agents make decisions based on environmental inputs.
• Task Execution: Processes for automating tasks with AI.

Practical Example

Develop an AI agent that can act as a personal assistant, automating tasks like scheduling or information retrieval.

7. Employing Data Augmentation Techniques

Data Augmentation in AI

Data augmentation techniques enhance datasets to improve model performance. Explore methods such as:

• Text Augmentation: Techniques like synonym replacement or back-translation.
• Image Augmentation: Using methods like rotation, flipping, or resizing.

Implementation Example

Use the nlpaug library to augment your text data easily.

import nlpaug.augmenter.word as naw

augmenter = naw.SynonymAug(aug_p=0.1)  # Augmenting 10% of words
augmented_text = augmenter.augment("This is a simple sentence.")
print(augmented_text)

8. Deployment Strategies for AI Models

Explore Deployment Techniques

Understand different strategies to deploy your models effectively. Consider:

• Containerization: Use Docker to ensure your applications run consistently across environments.
• Cloud Platforms: Explore services like AWS, GCP, or Azure for scalable deployment.

Practical Steps

• Deploy a model using Docker, making it accessible as a web service.
• Utilize CI/CD pipelines for seamless updates and maintenance.

Example of Dockerization

Create a Dockerfile to containerize your FastAPI application.

FROM python:3.9

WORKDIR /app
COPY . .
RUN pip install -r requirements.txt

CMD ["uvicorn", "main:app", "--host", "0.0.0.0", "--port", "8000"]
