Learning data science doesn’t have to feel dry. In this course, every dataset tells a story — and every story is a mystery to solve.Data Crime Stories is a unique, story-driven course where you step into the role of a data detective. Each chapter begins with a crime-inspired scenario — a missing passenger, a stolen necklace, a locked hotel suite, or a vanishing hiker. Your job: use Python, Pandas, and visualization to uncover the truth hidden in the data.You’ll investigate original crime-inspired stories — each built around real-world datasets. Scenarios include:Whispers at Dusk – A politician disappears at a foggy festival.Stillness on Floor Thirteen – A nurse sees a man not on the patient list.No Return from Room 9B – A hotel guest checks in but never checks out.Echoes at Blackwood Hall – A pianist collapses mid-performance.Glass Shards Guest Lists – A necklace vanishes at an island wedding.The Final Room Service – A journalist is found lifeless in her suite.The Forgotten Ticket – A poisoned actor during a premiere.The Midnight Departure – A missing passenger on a luxury train.The Widow’s Ledger – A disputed will in a countryside estate.Vanishing Point – A hiker goes missing.With each case, you’ll work through a Jupyter Notebook that guides you step by step through the analysis. By the end of every lecture, you’ll have solved a mystery — and mastered new data science skills along the way.How to follow alongUnder each lecture, download the Resources (.zip) with the dataset and the notebook.Split your screen between the video and the notebook to code side by side.P

This course contains the use of artificial intelligence.It features high-quality narration by professional voice actors, further refined with AI enhancement technology for crystal-clear audio. To ensure a dynamic learning experience, we also utilize AI-generated visuals to illustrate complex concepts effectively.Did you know that 70% of industrial digital transformation projects fail, getting stuck in endless cycles of "Pilot Purgatory"?In today’s competitive landscape, traditional, rigid automation and siloed legacy systems are no longer enough. You need agility, real-time intelligence, and scalable solutions that prove their financial value immediately for your technical enterprise whether it is in manufacturing, logistics or other commercial services.Welcome to Agile Predictive Monitoring: Lean Operations with AI IoT.In this comprehensive course, you will learn how to implement the Agile Predictive Monitoring (AgPM) framework to bridge the gap between complex industrial technologies (IIoT, AI) and real-world business realities (Lean operations, ROI) in an agile and smarter way. Taught by an industry expert and IoT company CEO, this course bypasses academic theory and focuses purely on practical, enterprise-level execution of A-IoT systems using the AgPM methodology.Here is what we will cover:Escaping Pilot Purgatory: Understand the hidden costs of DIY internal tools and why legacy "waterfall" planning kills industrial innovation.The AgPM Nervous System (IoT Connectivity): Compare wired vs. wireless sensors and learn how to deploy a "Digital Retrofit" using hybrid networks (5G and LoRaWAN) in minutes.The Brain (Data Architectures): Eliminate

Snowflake has quickly become one of the most popular cloud data platforms used by modern data teams. In this hands-on course, you’ll learn how to use Snowflake to load, transform, analyze, and visualize data using real data analytics workflows.This course is designed for beginners and aspiring data analysts who want to develop practical Snowflake and SQL skills used in real-world data projects.You’ll start by setting up your Snowflake environment and learning how to work with databases, schemas, and stages. From there, you’ll load and explore data from multiple formats including CSV, JSON, and Parquet files.Next, you’ll focus on data preparation and cleaning, an essential skill for any analyst. You’ll learn how to identify and remove duplicates, validate email addresses, clean phone numbers, and resolve inconsistencies using SQL functions and subqueries.Once the data is prepared, you’ll dive into data analysis and transformation using powerful SQL features. You’ll work with aggregations, window functions, ranking, CTEs, and materialized views to analyze complex datasets efficiently.You’ll also learn important data modeling concepts, including Star Schema, Snowflake Schema, and Data Vault, helping you understand how analytical data models are structured in modern data warehouses.Finally, you’ll create interactive dashboards in Snowsight, where you’ll visualize insights using charts, filters, and scorecards. You’ll also learn how to securely share dashboards, apply row access policies, and connect Snowflake to BI tools.By the end of the course, you’ll be able to:Load and manage data in SnowflakeClean and prepare messy datasets using SQLPerform advanced data analysis using window functions and aggregationsUnderstand common analytical data modelsBuild dashboards and visualize insights in Snowsight

This course is a practical, step-by-step guide to creating a complete YouTube Short using AI, demonstrated through a real puppy face project.Instead of teaching isolated tools or theory, this course focuses on a single end-to-end workflow. You will start with an input reference video and use it as inspiration to recreate a new output video using AI techniques. Every step is shown clearly so you can follow along and understand the full creative process.The course demonstrates how to plan a short video, prepare reference material, generate AI visuals, assemble scenes, and combine everything into a finished YouTube Short. The example project uses a puppy face concept to make the learning visual, engaging, and easy to understand, while keeping the focus on the AI workflow itself.You will see how to structure scenes, maintain visual consistency, and build a short narrative suitable for YouTube Shorts format. The entire process is explained in a simple and practical manner, making it suitable even for beginners.This is a hands-on project-based course. By the end of the course, you will have a clear understanding of how to take an idea, apply AI tools step by step, and produce a complete short-form video ready for upload.This course is ideal for creators who want to learn by doing, rather than through theory-heavy explanations.
