Introduction to Agentic AI

Agentic AI represents a paradigm shift in artificial intelligence, where AI systems are designed to be autonomous agents capable of perceiving their environment, making decisions, and taking actions to achieve specific goals. Unlike traditional AI, which typically requires explicit instructions for each task, Agentic AI can dynamically adapt and respond to new situations.

Understanding Retrieval-Augmented Generation (RAG)

Retrieval-Augmented Generation (RAG) is a technique that enhances the capabilities of large language models (LLMs) by integrating external knowledge sources. Instead of relying solely on pre-trained knowledge, RAG models retrieve relevant information from a knowledge base and use it to generate more accurate and contextually appropriate responses.

Key Components of Agentic AI Systems

• Perception: The ability to understand and interpret sensory inputs from the environment.
• Decision-Making: Algorithms that enable the agent to choose the best course of action.
• Action Execution: Mechanisms for carrying out the agent's decisions.
• Learning: The capacity to improve performance over time through experience.

How RAG Works

1. Query Encoding: The input query is encoded into a vector representation.
2. Knowledge Retrieval: Relevant documents or passages are retrieved from a knowledge base using similarity search.
3. Context Augmentation: The retrieved information is combined with the original query.
4. Text Generation: The augmented context is used to generate a response.

Skills Developers Need in 2025

• AI Fundamentals: A solid understanding of AI concepts, machine learning algorithms, and neural networks.
• Programming Skills: Proficiency in languages like Python, Java, and C++.
• Knowledge of LLMs: Experience with models like GPT-3, BERT, and their application in RAG systems.
• Data Engineering: Skills in data processing, storage, and retrieval.
• Cloud Computing: Familiarity with cloud platforms like AWS, Azure, and Google Cloud.

Practical Java Example of Simple RAG Implementation

While a full RAG implementation is complex, this Java snippet demonstrates a basic information retrieval step:

     
 import java.util.ArrayList;
 import java.util.List;

 public class SimpleRAG {

  public static void main(String[] args) {
   String query = "What is Agentic AI?";
   List<String> documents = getDocuments(); // Assume this retrieves documents from a database

   String relevantDocument = retrieveRelevantDocument(query, documents);

   System.out.println("Query: " + query);
   System.out.println("Relevant Document: " + relevantDocument);
  }

  public static List<String> getDocuments() {
   List<String> documents = new ArrayList<>();
   documents.add("Agentic AI are autonomous agents capable of perceiving their environment");
   documents.add("Java is a popular programming language.");
   documents.add("RAG enhances LLMs by integrating external knowledge.");
   return documents;
  }

  public static String retrieveRelevantDocument(String query, List<String> documents) {
   // Simplistic relevance check (keyword matching) - In reality, use embeddings and similarity search
   for (String document : documents) {
    if (document.toLowerCase().contains("agentic ai")) {
     return document;
    }
   }
   return "No relevant document found.";
  }
 }
