NeuronPingNeuronPing is a website about AI and agentic AI. Read here how AI agents work, and get better with them.https://neuronping.com/enWhat is an agent harness? How it works, its parts and use caseshttps://neuronping.com/topics/what-is-an-agent-harness/https://neuronping.com/topics/what-is-an-agent-harness/Learn what an agent harness is, how its loop runs a task and what its parts are: context, tools and permissions, what is kept between sessions, and hooks. Tests by OpenAI and Anthropic show how much a harness changed a model's results, and both companies describe harnesses for particular kinds of work.Sun, 08 Nov 2026 00:00:00 GMTAgent HarnessAI AgentKeyword, semantic and knowledge graph search: hybrid search explainedhttps://neuronping.com/topics/keyword-semantic-and-knowledge-graph-search/https://neuronping.com/topics/keyword-semantic-and-knowledge-graph-search/Keyword search, semantic search and knowledge graph search are three ways to retrieve data for an LLM or an AI agent. This guide covers how each one works, how they differ, how hybrid search combines them with rank fusion and a reranker, and the best use cases for each.Thu, 08 Oct 2026 00:00:00 GMTHybrid SearchKnowledge GraphAI AgentSigmoid and softmax functions: how they work and when to use eachhttps://neuronping.com/topics/sigmoid-and-softmax-functions/https://neuronping.com/topics/sigmoid-and-softmax-functions/Sigmoid and softmax turn the scores of a classifier into probabilities. The sigmoid turns one score into a probability between 0 and 1. The softmax turns several scores, one per class, into probabilities that sum to 1. This article explains both with formulas and examples, and shows when to use each.Thu, 08 Oct 2026 00:00:00 GMTSigmoidSoftmaxTransformerWhat is Hindsight? Agent memory, knowledge graph and use caseshttps://neuronping.com/topics/what-is-hindsight-agent-memory/https://neuronping.com/topics/what-is-hindsight-agent-memory/Hindsight is a memory system for AI agents. This guide explains why agents need memory, why entities and a knowledge graph help, how the operations retain, recall and reflect work, how Hindsight differs from RAG, and its use cases.Wed, 07 Oct 2026 00:00:00 GMTHindsightAgent MemoryKnowledge GraphWhat is MCP (Model Context Protocol)? How it works and its use caseshttps://neuronping.com/topics/what-is-mcp/https://neuronping.com/topics/what-is-mcp/MCP, the Model Context Protocol, connects AI applications such as Claude, ChatGPT and AI agents to tools and data. This guide covers how MCP works, its architecture, how it differs from an API, its use cases and its limits.Wed, 07 Oct 2026 00:00:00 GMTMCPAI AgentAI workflows and agent skills: what they are and how to use themhttps://neuronping.com/topics/ai-workflows-and-agent-skills/https://neuronping.com/topics/ai-workflows-and-agent-skills/This guide explains what AI workflows and agent skills are, how they differ, how to choose, and how real systems use the two together.Mon, 05 Oct 2026 00:00:00 GMTAI WorkflowAgent SkillAI AgentWhat is Hermes Agent? How it works, its structure and use caseshttps://neuronping.com/topics/what-is-hermes-agent/https://neuronping.com/topics/what-is-hermes-agent/Hermes Agent is an open-source AI agent from Nous Research that runs on your own computer or server, uses tools to carry out tasks and remembers what it learned.
