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.

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.

Let’s play with colours this time. Treat the colour as subject or splash some colours around the subject you choose to shoot. For a keen eye, the opportunities are abundant on the street. Capture emotions of single or multicolours… look for colours around things, people, storytelling, or even go abstract… Have a look at some pictures on the theme in this event’ album below. **Meeting Time & Place:** **4pm** at **Central MTR Station Exit K** (street level) We will meet at **Central MTR Station Exit K (street level)** at **4pm,** move around the Central area taking pictures, and then re-group at a café/bar (yet to be decide) **5:30pm** onwards for photo sharing and socialising over a drink. Please post **YOUR BEST FIVE IMAGES** only for this outing on the meetup site. **FINALLY:** For every image you post, please comment on at least one other image, no matter if you think you are qualified to comment or not. You can always give some constructive comments with regard to Colour, Tone, Light, Action, Pattern, Balance, Composition, Visual and Emotional appeal of the image/s. This group is about sharing and learning from each other.

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.

To enjoy this hike-swim event in safety, we’ll take boat from Pak Sha Wan Pier in Sai Kung to secluded nature Pak Shui Wun(白水碗) , then we trek to turquoise Campsite Beach(露營灣) for swimming. Let’s explore WWII anti-invasion Pillbox機槍堡 (PB)107 & 108 if possible. As they are hidden at the coast of Chuk Kok opposite to sea of Trio Bay, it means no shop or any replenishment support. **Be fully equipped** with hike & swim gear *under the heat*. According to a study on the relics of the territory’s pillboxes (PBs) by The University of Hong Kong, “Hong Kong’s PBs are internationally significant due to their unique designs, and the accumulation of scientific knowledge about them, particularly in oral history, mapping, photography, and surveying. " "They also hold value in academic and professional domains including dissemination, appreciation, and curatorship. Compared to other places, such as Singapore, **Hong Kong’s work in this field is more advanced**.” Please bring two litres of sports drinks & your lunch box with snacks. No store or any replenishment support there. Sandals or anti-slippery swim shoes will be useful if you wet your hiking shoes during a little coasteering. There is **NO** **lifeguard** in Campsite Beach, ***swimming is for experienced swimmers* only.** Bring an umbrella or light tent for sheltering, if you just want to enjoy the rest on the sand! By 5pm, we will take the booked boat back to either Pak Sha Wan Pier or Sai Kung Pier.

**History** The [Franklin Park Conservatory](https://www.fpconservatory.org/)’s roots trace back to 1852 when the Franklin County Agricultural Society purchased 88 acres of land to host the Ohio State Fair. After the fair moved to its permanent home, the city of Columbus transformed the grounds into Franklin Park in 1884. This transition shifted the space from a temporary event site to a dedicated public green space for the growing community. The park became a central hub for outdoor recreation and early civic gatherings in the neighborhood. In 1895, the landmark Victorian-style Palm House opened its doors, drawing heavy inspiration from the Glass Palace of the 1893 World’s Columbian Exposition in Chicago. This iron and glass structure became an immediate icon, housing exotic plants that residents would otherwise never see in the Midwest. It remains the oldest part of the facility and serves as a primary link to the conservatory’s 19th-century origins. For decades, it stood as a singular testament to grand horticultural architecture in Central Ohio. A major turning point arrived in 1992 when Columbus hosted AmeriFlora '92, an international horticultural exhibition. This massive event prompted a $16 million renovation and expansion, adding significantly more greenhouse space and the Dorothy M. Davis Showhouse. The festival put the conservatory on the international map and fundamentally changed its scale and ambition. Following the event, the facility transitioned from a city-run park to a private, non-profit organization. In 2003, the conservatory’s identity was further defined through a long-term partnership with world-renowned glass artist Dale Chihuly. After a successful exhibition, the Friends of the Conservatory purchased most of the glass installations, creating the largest permanent collection of Chihuly’s work in a botanical setting. These vibrant glass sculptures are now woven throughout the biomes, blending art with nature. This addition helped cement the conservatory as a premier cultural destination rather than just a botanical garden. Recent years have seen the site expand beyond the glass walls to emphasize community engagement and outdoor education. The 2018 opening of the Scotts Miracle-Gro Foundation Children’s Garden added two acres of interactive landscape designed for hands-on learning. The Scotts Miracle-Gro Company Community Garden Campus also provides local residents with space to grow their own food and learn sustainable practices. Today, the conservatory balances its historic Victorian charm with modern commitments to local ecology and the Columbus community. **Maps of the Conservatory** Here is the [main map](https://www.fpconservatory.org/wp-content/uploads/2025/08/franklin-park-zones-scaled.jpg) of the Conservatory grounds. Here's a [map of the areas](https://www.fpconservatory.org/wp-content/uploads/2026/02/ConstructionMap-2026.jpg) in which the Conservatory has ongoing construction (see below). **Summary** For this event, we'll explore Columbus's highly-rated and very popular Conservatory. As mentioned above, the Conservatory is doing renovations on parts of the facility. These renovations are scheduled to be ongoing until the Fall of next year. Basically, no matter when you go to the Conservatory over the next 18 months, you're going to see some metaphorical orange barrels. So let's just go now. **Tickets and pricing** On the first Sunday of every month, the Conservatory is free for residents of Franklin County and the city of Columbus. You must bring an ID to receive this discount. (Yes, they do check.) Otherwise, tickets are $25.20. Members of the Columbus Zoo (of which I am one) do get a discount on tickets, though I have never actually bought a ticket to the Conservatory (I've always gone on free days). I believe the discount is $4. Parking is always free. If you have additional questions about pricing or whether and for what you qualify, you can reach the Conservatory at 614-715-8000. **Where we'll meet** We will meet just outside the main entrance. I guarantee there's going to be a line. The Conservatory is always popular on free days, and especially in nice weather. **Your GPS is stupid!** Be careful simply typing "Franklin Park Conservatory" in your GPS and going where it tells you. The only way to access the parking lot to the Conservatory is off of Broad Street. Unfortunately, since Google Maps is unable to find its way out of a wet paper bag, it has a tendency to want to take people to a mythical, non-existent Conservatory entrance on Nelson Road. If your GPS does this, just drive to the north side of the Conservatory along Broad Street. Your GPS should then redirect you to the main Conservatory entrance. If your GPS doesn't, then throw your phone away\* and look for the big Conservatory sign on the south side of Broad Street between Nelson Road and Franklin Park West. You also should be able to use the map pin I've provided, below, and it should properly direct you to where you need to drive. \* Don't really do this. **After the event** After stopping to smell the roses, for those that are interested, we'll head to the nearby [Columbus Brewing Company Beer Hall](https://columbusbrewing.com/location/beer-hall/) for [drinks](https://columbusbrewing.com/location/beer-hall/#draft-list) and [lunch](https://columbusbrewing.com/location/beer-hall/#food-menu). The Beer Hall's actual address is [200 Kelton Ave, Columbus, OH 43205](https://www.google.com/maps/place/200+Kelton+Ave,+Columbus,+OH+43205/data=!4m2!3m1!1s0x883889a94ac4acad:0xadb2e60240dbc38b?sa=X&ved=1t:242&ictx=111) (it's literally just on the south side of the Conservatory). Be sure this is where your GPS is taking you when you use it, as the Brewing Company has a taproom on Harrison Avenue that is *not* what you want for this event. We should be at the Beer Hall by 1 if you can't make the Conservatory and just want to join us for drinks.
