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.

亨利.穆傑的法國經典小說 +意大利19世紀末最重要的歌劇作曲家賈科莫.普契尼的著名歌劇《波希米亞人》藍本 +法語演唱。 故事：一群年輕人在 從放蕩不羈的青春 步向 肩負責任的成年 之間，如何在缺乏生活保障的情況下，依然追求藝術理想與愛情。 “Scenes of Bohemian Life” is a work by Henri Murger, published in 1851. a collection of loosely related stories, all set in the Latin Quarter of Paris in the 1840s, romanticizing bohemian life in a playful way. 2 operas were later based on the novel and play, *La bohème* by Giacomo Puccini in 1896 and *La bohème* by Ruggero Leoncavallo in 1897. Puccini's became one of the most popular operas of all time, spawning several later works based on the same story. **日期：2026年5月30日(星期六)** **時間：1)食飯:@6:15-7:00pm (可選), 2)音歌劇:@7:30-9:15pm** **地點：香港理工大學** **集合時間及地點：1)理工大學VA樓canteen; 2)賽馬會綜藝館地面層; 電聯** **座位: 自由劃位(本人會於7:30pm先排隊入場為大家獲取好座位)** **主辦單位：法國五月藝術節、理工大學、香港歌劇院** Date: 30 May, 2026 (Saturday) Time: 1) Dinner @6:15-7:00pm; 2) Opera @7:30pm-9:15pm Address: JC Auditorium in Hong Kong Poly University Assemble: 1) canteen in VA Building; 2) G/F of JC Auditorium; by call Seat: 6 people limited (Other audience in event as well) Seating: No seating is set and seats are served on first-come-first-served basis (I will queue up for good seat at 7:30pm for members) Presented by: French May Arts Festival, HK Poly University, Opera Hong Kong MeetUp費用：自由定價價值,(晚餐費另計). 報名：按Attend-> 填寫1)聯絡電話號碼, 2)男/女, 3)你願意付出此次活動費用, 4)一起用餐否?-> 確認入選活動-> 繳費(入帳恆生銀行號碼: 359-366101-882 (NG Y\*\ \*S\*\*\*)/ FPS/PayMe: 97419423)-> 再以閣下電話whatsapp(97419423)以下資料: 1)MeetUp名字, 2)過帳通知書.
