Date: 30 May 2026 (Sat) Time: 15:30 - 18:00 \*HKT Coordinator: Ming Tou, Alex Au Light Refreshments will be available! This is a **workshop** for Python Data Cleaning. Please bring along your laptop with **Python3 installed with enough battery**! *Winners will get a small prize as an accomplishment **in the next meetup**.* **Due to the university entrance policy, we are currently closed for new university QR code entrance registration. Please feel free to join us by registering yourself under the university entrance counter!** ***Mind the Data Gap*** **This model will be delayed due to: missing values, outliers, and delimiter congestion.** In this hands-on HKPUG workshop, we are turning a Python data cleaning exercise into a gamified team sprint. You will work with a **synthetic Hong Kong-inspired transport dataset**. The data is messy on purpose: missing values, weird outliers, inconsistent categories, URL-encoded station names, confusing delimiters, and fields that look useless until you extract the hidden signal. Your mission is simple: **Clean the data. Extract better features. Run the scorer. Beat the model.** You do not need to tune the model. You need to **rescue the data**. ***How the Challenge Works*** Teams will write a Python data transformation script to clean and enrich the dataset. Our scoring pipeline will then: 1. Run your transformation on the training and test data 2. Remove any label / target leakage columns 3. Train a fixed Gradient Boosting model 4. Evaluate the model using proxy metrics such as F1 and ROC-AUC 5. Convert the result into a data cleaning score This is not meant to be a perfect data quality metric. It is an accessible proxy: if your **cleaning** and **feature extraction** help the **model perform better**, your team gets a better score. **Capacity:** 60 (Team of 4) **Venue Info:** City University of Hong Kong, Kowloon Tong (Exact Location TBC) **Rundown:** **30th May** **15:30 – 15:40** Opening Remarks, Team Formation & GitHub Setup **15:40 – 15:55** Briefing: Data Traffic Report, Challenge Rules & Scoring Pipeline **15:55 – 16:20** Demo: Messy Dataset, Data Cleaning Strategy & `transform.py` **16:20 – 17:10** Team Sprint Part 1: Missing Values, Outliers & Category Cleanup **17:10 – 18:00** Team Sprint Part 2: Feature Extraction, Hidden Signals & Scoring Iterations **18:00 -** Networking outside City University **13th June** **\- 23:59** Winner Team Announcement **Audience pre-requisite:** * **Hardware:** **MUST** bring a laptop with Python 3 installed and a code editor (VS Code, PyCharm, etc.). * **Skills:** Recommended having basic to intermediate-level knowledge of Python (handling JSON, using the `requests` library, and writing basic `if/else/while` loops). **How to join?** 1.

When learning statistics, one of the most fundamental yet usually grossed over concepts is that of **variance** (i.e. the square of the standard deviation in normal distribution). As we know, virtually all statistical operations which measure deviations of individual values from the norm involve adding the **SQUARED differences between the two numbers**. However, very few instructors could explain why we have to use squares rather than just the absolute values of the difference (or other even powers such as 4, if the intention is to avoid the negatives). This tutorial shall cover this in a convincing manner. Secondly, while we all know the variance of a SAMPLE is arrived by dividing (n-1) of the sum of squared differences, where n is the number of observations, few can articulate the rationale behind it. This tutorial shall also prove step by step why this is case, so after this you could appreciate the logic behind this ingenious insight instead of just reciting it like a medieval myth.

Most people still use AI like a search box: type one question, get one answer, repeat. But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review. In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity. We’ll cover: * What makes an AI “agent” instead of just a chatbot * How agents break tasks into steps * Where agents are genuinely useful today * Where they fail, hallucinate, or need human review * How to design simple AI workflows for your own work * A live demo of an AI agent-style workflow from start to finish No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
