Professional Development

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.

**Join us with your favourite books! Meet up with a bunch of curious minds. Let’s take a sip and share about what we are reading!** **During the book sharing session, we will take turns to share about what we’ve been reading. You can also share some excerpts from the book as well. The conversation starts there. Hopefully, by learning about others' reading interests, we can expand our own original reading scope.** **Later on, we could also reflect and share about our last month’s reading habits and methods, etc.** **Book swap is not compulsory. If you have books to give away, feel free to bring them along, and we will be happy to take them for future events.**

Hi guys, I write a free newsletter about AI, tech, entrepreneurship, and Hong Kong called *Better Read Paul* ([Paul Muller | Substack](https://substack.com/@paulmuller)). While working on it, talking to founders, and seeing how people actually use AI day to day, I kept noticing the same thing: there’s a lot of excitement about AI, but very little practical guidance. At the same time, AI has become a big part of my own daily work. I use it constantly to move faster, think more clearly, and save time. And that’s what pushed me to organize these workshops. The idea is simple: very little theory, and as much hands-on practice as possible. This is not a class where you listen to me talk for two hours, but rather a big conversation where I’ll show you how to use these tools (Claude Code, Nano Banana, ChatGPT, etc.), what you can do with them, and how you can apply them to your own workflow depending on what you do. We will cover: * How to use Claude Code to build a WordPress website and a simple program to learn a language * How to use Claude to rewrite a LinkedIn post or any other social media content * How to use Nano Banana to create a marketing canvas for any brand Cost: 200HKD for 1h45 Place: Unit 280, 6/F Ping lam commercial building, 280-282 Lockhart road, Wanchai Time: 11am-1pm What to bring: A notepad, your laptop (Only if you need help and already use some AI tools). AI can be incredibly useful, but there are a few things people don’t always tell you. Many tools are paid. The results don’t always live up to expectations. Some tools crash, go down, or need maintenance right when you need them most. And many of them magically produce perfect output without effort. So in the end, the real questions are: what actually slows you down every day at work? Can an AI tool help with that? Is the quality good enough? And is it worth paying for, given the time you save? That’s why I want to run these AI workshops, to help people understand how these tools really work, and to give them the space to experiment and apply AI to their own workflows in a practical and realistic way. Paul

Reading is important because it develops your mind and gives you excessive knowledge and lessons of life. 開卷有益！大家最近有冇讀到一啲好書呢？不如出黎分享下讀書心得呀？參加呢個讀書活動，分享好書，分享喜悅。😊 有興趣參加可以WhatsApp我：95182994

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.

**The Behavior Gap: Where Products Win or Lose** Teams today have more data than ever, and yet many still struggle to understand why customers adopt, engage with, or abandon their products. Teams sprint, ship faster, and chase more signals… all while metrics stall and confidence drops. The missing piece isn’t more data. It’s often the behavioral insight between the metrics, explaining why the numbers move in the first place. Dashboards can tell you what customers did, but understanding why they did it (and how to influence what they do next) requires a deeper blend of insights. This session is about closing that gap. Drawing from real-world experience designing and scaling products as [ZoCo Design](https://zocodesign.com/)’s CEO, [Lacey](https://www.linkedin.com/in/laceypicazo/) will share how to cut through the noise and identify the insights that actually change behavior—moving people, and moving metrics. You’ll learn: * Why understanding customer behavior is a quant and qual challenge * How to spot the signals that actually predict behavior change * Where AI accelerates insight, and where it creates distraction * How to get meaningfully closer to customers, without adding more tools This talk reframes how to evaluate performance and identify what levers actually improve it, helping your team to make smarter bets with greater confidence. Every meaningful outcome is driven by behavior change. And when you know how to design for behavior, you stop guessing, and start building things that work. **About Our Speaker** [Lacey Picazo](https://www.linkedin.com/in/laceypicazo/) is the Founder and CEO of ZoCo, a healthcare product studio that turns complex, high-stakes ideas into products that drive real-world adoption. She partners with healthcare organizations to uncover critical care delivery insights, focus product strategy through behavior design, and build solutions that patients and providers actually use.
