Introduction

Model-free reinforcement learning learns a policy directly from experience, but it can struggle to discover useful representations from sparse or noisy rewards. Model-based reinforcement learning receives a denser training signal by learning how states, actions, rewards, and termination relate to one another, but it often pays for that knowledge through planning complexity and model error.

Can a model-free agent keep the representation-learning benefits of a learned model without using that model to plan?

Summary

Machine learning operates on data. Essentially, it processes data to extract meaningful information, which can then be used to make intelligent decisions. This is the foundation of Artificial Intelligence. The more data you have the better your machine learning apps will be. There is a caveat though the data has to be high quality. The more data you have and the higher quality the better your apps will be.

Artificial Intelligence (AI) has revolutionized the way we generate and consume text. From chatbots crafting customer responses to AI-authored articles, artificial intelligence is reshaping how we create and consume content. As AI-generated text becomes indistinguishable from human writing, distinguishing between the two has never been more critical. Here are some of the reasons it is important to be able to verify the source of information:

• Preventing plagiarism
• Maintaining academic integrity
• Ensuring transparency in content creation
• If AI models are repeatedly trained on AI-generated text, their quality may degrade over time.

In this blog post, we’ll explore the current most effective methods for detecting AI-generated text.

Could the greatest playwright of all time have secretly shaped one of the most influential religious texts in history? Some believe William Shakespeare left his mark on the King James Bible hidden in plain sight. With the power of AI, we’ll investigate whether there’s any truth to this conspiracy.

Vector databases are essential for modern AI applications like semantic search, recommendation systems, and natural language processing. They allow us to store and query high-dimensional vectors efficiently. With the pgvector extension PostgreSQL becomes a powerful vector database, enabling you to combine traditional relational data with vector-based operations.

In this post, we will walk through the full process:

Installing PostgreSQL and pgvector Setting up a vector-enabled database Generating embeddings using Ollama Running similarity queries with Python By the end, you’ll be able to store, query, and compare high-dimensional vectors in PostgreSQL, opening up new possibilities for AI-powered applications.

Summary

The evolution of technology is driven by protocols structured ways for systems to communicate and interact. The internet, APIs, and even modern databases rely on protocols to function efficiently. Similarly, as AI becomes more powerful, it needs a structured and standardized way to manage context across interactions.

Enter the Model Context Protocol (MCP) a framework designed to enhance the way AI models understand, retain, and utilize context over multiple exchanges. Large Language Models (LLMs) are powerful, but without effective context management, they can:

In AI and data science, knowledge graphs are powerful tools for modeling complex relationships between entities. They enable intelligent querying, recommendation systems, and semantic search. Neo4j, an open-source graph database, is one of the most popular tools for building and managing knowledge graphs.

In this post, we’ll walk you through setting up Neo4j, configuring it for use as a knowledge graph, and manipulating the database using Python.

Summary

Function calling allows Large Language Models (LLMs) to interact with APIs, databases, and other tools, making them more than just text generators.

Integrating LLMs with functions enables you to harness their powerful text processing capabilities, seamlessly enhancing the technological solutions you develop.

This post will explain how you can call local python functions and tools in Ollama.

Introduction to Ollama Function Calling

Ollama allows you to run state-of-the-art LLMs like Qwen, Llama, and others locally without relying on cloud APIs. Its function-calling feature enables models to execute external Python functions, making it ideal for applications like chatbots, automation tools, and data-driven systems.

Summary

What if AI isn’t just a tool but the foundation of how you work, create, and think?

Today there are two distinct ways to approach AI: +AI and AI+. +AI means integrating AI into an existing workflow, business, or process. It’s the approach discussed in countless books, YouTube videos, and business strategies. If you’re working, running a business, or earning money, this is the natural and logical way to use AI. But this post isn’t about that. Instead this post is about AI+ a radically different approach where AI is the foundation of everything you do.

Summary

In this post, I will demonstrate how to set up and use haystack with Ollama.

haystack is a framework that helps when building applications powered by LLMs.

• It offers extensive LLM-related functionality.
• It is open source under the Apache license.
• It is actively developed, with numerous contributors.
• It is widely used in production by various clients.

These are some of the key items to watch for when using a library in a project.
