Core Principles of n8n Automation and Workflow Design Basics for Non-Majors 5-Step Automation Built with n8n: API Connection Practice from Topic Input to Video Completion How to Automatically Create Videos in n8n Using AI APIs (ChatGPT, ElevenLabs, Creatomate)

: "From Mathematical Foundations to the Latest Models, Completing the Deep Learning Pipeline with PyTorch (44 Lectures in Total)" The era of simply learning how to call model.fit() is over. From the very basics of artificial neural networks—differentiation and gradient descent—to essential PyTorch techniques used in the industry, and CNN/RNN for handling image and time-series data! We will help you systematically master the entire process of deep learning. Go beyond analyzed data and step into the amazing world of deep learning, where artificial intelligence mimicking the human brain learns and makes decisions on its own.

This is a 'Practical Linux Troubleshooting Course' where you analyze and solve problems together with generative AI, based on a Docker practice environment that reproduces 5 representative failures that occur in actual Linux operating environments. Even those who were overwhelmed about where to start examining problems can learn the problem-solving approach and thought process of field engineers through AI guidance.

Moving beyond prompt engineering and context engineering, we are now entering the era of harness engineering. Harnesses can solve LLM-based challenges that are difficult to achieve with prompts and RAG alone.

This video shows effective ways to link internal company data to sLM, and practical solutions for various issues from sLM adoption.

I will teach you Vibe Coding systematically from the ground up, following the exact curriculum refined by a 10-year veteran tech lead from NYC/LA startups who has taught over 10,000 students. We will build 'Kagong Map'—a service I personally operate—from scratch, learning the entire real-world workflow from research and development to deployment, operations, and even automation by delegating tasks to AI agents. And I promise you two things: first, you will grasp the big picture of how a service works so you can evaluate AI outputs yourself; second, you will learn to embed workflows and standards into the environment so that AI produces consistent results every time. When you can make the judgments and the AI follows your lead, your ideas truly become real services.
