AI in Production: Vectors in the Newsroom & Healthcare Challenges
GDG Cloud London is thrilled to be partnering with Skyscanner for a deep dive into the world of AI applications in Production.
This meet-up is a unique opportunity to connect with fellow AI enthusiasts, industry practitioners, and researchers in a dynamic and interactive setting. We are going to have some pizza and networking at the end!
Don't miss out, RSVP now!AGENDA
18:00 - Doors Open & Check-ins
18:30 - Welcome & Intro
18:40 - Ellen Muller - Vectors in the Newsroom: Building Smarter Image Search at the Guardian.
When a photo editor searches our image management system for "protest" at 6pm on a deadline, they can't afford to get zero results because the images were captioned "demonstration." Traditional keyword search has no way to know those mean the same thing - and for an archive with inconsistent metadata, that gap matters. This talk is about how we added semantic search to the Grid (the Guardian's open source image management system) using embeddings and vector similarity. We'll dig into how vector spaces let you encode meaning rather than just text, and the practical choices (and mistakes) involved in shipping this into a real production system.
19:15 - Bruno Ripa - Technical challenges of AI adoption in Healthcare
Deploying AI in healthcare requires solving a shifting equation: balancing high-fidelity clinical utility against rigorous data sovereignty mandates and punishing infrastructure costs. This talk breaks down how our company navigates this fluid landscape daily. We will cover where we use AI in our stack, how localised data compliance continuously reshapes our engineering choices, and the concrete technical hurdles we encounter along the way. Rather than showcasing a finalised architecture, we will focus on the ongoing design decisions and trade-offs required to keep our product secure, reliable, and compliant, all while aggressively optimising compute and operational costs—proving that surviving the mutating challenges of healthcare AI is a continuous process of lean execution.

Rabble - Fitness Through Games!
A Rabble session is 1 hour of fun and social team games.
Each game disguises high-intensity intervals within the rules, giving you an effective, all-body workout without even realising it.
We play a bunch of different games at each session (like British Bulldog, Capture the Flag, Dodgeball, Frisbee and many more), and every class is different.
Sessions are open to all, no matter your sporting ability. Each game is explained before we start, so there's no need to have played any of the games before.
Come solo or bring friends! And stay at the end for the social part!
Who knew getting fit could be this fun?

#### Our Drop-Ins
Improv is the art of making things up on the spot and feel immensly proud of it as there is no judgement. Our workshops are designed to be gentle, fun and inclusive. Being on the spot can feel scary and overwhelming. We make sure that you feel supported and at ease at all times. Improv is an amazing tool to **boost your confidence and ability to connect to other humans**, it helps you be creative and let the inner judge go and sip a tea whilst you have fun discovering how freeing being sponteanous can be.
Our weekly drop-in classes explore both general topics and specific areas of improv. Story-telling, emotional connection and creative collaboration are the key aspects we focus on, with exciting niche topics designed to stretch you in a safe and playful environment.
**Stepping out of your comfort zone should feel fun and exciting** \- we make sure you feel supported and encouraged in the best way possible\, while connecting with others and creating a bit of magic together\.
These classes are open to all, **our gentle approach specifically focuses on people who struggle feeling confident in social settings**, however, if you have done improv before, you will certainly find joy coming to our drop-ins.
The first half of the lesson we will focus on group and exercises in pairs
The second half will be more scene-based where you can showcase your unique self. No pressure to perform. You will be amazed how you will shine with little effort.
The drop-ins run either Mondays or Tuesdays from **6:30pm–8:30pm** and are designed as stand-alone classes, so you don’t need to worry if you miss a week.
#### What is improv, you ask?
Improv is creating something in the moment — unplanned and unscripted. It’s about listening and building something together with others: the ultimate collaboration.
Improv is also a great tool for enhancing creativity and for life in general. It encourages spontaneity and connection in a playful, non-judgemental way.
#### Who We Are
Karo and Avril have over **20 years of cumulative experience** within the improv community. They have performed together in a wide variety of shows and formats for many years, as well as teaching and facilitating workshops, classes, and training sessions.

Avril is an improviser and actress who has been performing improv for over 12 years. Her credits include *Upstairs Downton: The Improvised Period Drama*, *Carmen: The Improvised Film Noir*, *Moments In Time*, *Blend Off*, *ImprovShire*, and *The Improvised Play*.
Avril is also a founder member of LadyProv, who run a regular night at Hoopla showcasing the talents of women and non-binary performers.
She has led numerous improv workshops and loves teaching. Her interests include Stoppard, character work, the senses, disaster movies, and team building in the workplace, to name a few. She has a particular passion for narrative improv and enjoys exploring different theatre styles. Avril has also co-taught with Stephen Davidson at Impromiscuous.
Outside of improv, Avril loves whisky and exploring how taste, environment, and food pairings influence creativity. She enjoys writing short stories and has written her own one-woman show combining stand-up, character, improv, and sketch. She can also be heard playing several characters in *Lusus*, a modern-day horror series on BBC Sounds.
#### Karolina
Karolina is an actor, improviser, and improv coach originally from Austria, who has been performing improv for over 12 years on stages across the UK and Europe. From short-form improv to fully improvised plays, she has explored a wide range of genres.
She has performed with groups such as Scumbags (a Hoopla house team in the style of the Coen Brothers), *Carmen* (a gender-flipped Film Noir), *3 Worlds*, the short-form comedy group Improvable, and *Lost to Life*, where she improvises an entire play with Avril and the team in the style of different playwrights.
Karolina has facilitated many classes over the years, including weekly drop-ins for people who feel shy, focused workshops for theatre companies, the Surrey Theatre Academy, corporate clients, and co-teaching with Impromiscuous.

The Science of Can and Can't - Chapter 6, Week 2
This week we'll discuss the sixth chapter of [The Science of Can and Can't](https://www.amazon.co.uk/Science-Can-Cant-Physicists-Counterfactuals/dp/0241310946/ref=sr_1_1?crid=1YFBGHPLNB4NO&dib=eyJ2IjoiMSJ9.YoSj1NdZXBPKK81RKKOjBA.ga2ZS1YEzf0cR13hyK4BpEHaXtvmjSfEhGZemtNXrLU&dib_tag=se&keywords=the+science+of+can+and+can%27t&qid=1779107463&sprefix=the+science+of+can+and+can%27t%2Caps%2C136&sr=8-1), by Chiara Marletto, co-developer of Constructor Theory alongside David Deutsch. This is the second of two discussions on this chapter.
A big theme of the book is counterfactuals - statements about what *could* happen, not just what *does* happen. Chiara argues that science has historically struggled to incorporate these rigorously, even though they’re central to explanations, computation, biology, knowledge, and agency.
If this is your first time attending we meet in the cafe of the Barbican Cinema - look for people with copies of the book.
Please read the chapter before attending.

Supersense: From Superstition to Religion by Bruce M. Hood
In this event, we will discuss about a science or philosophy book chosen by London Science and Philosophy Book Club. The attendees will be divided into groups and each of them will focus on a chapter in the book. This month we will discuss about a fascinating book called Supersense: From Superstition to Religion by Bruce Hood. If you haven't read the book, it's no problem. I will bring you up to speed with the discussion materials.
We will meet in a nice lounge area at 6 p.m for introductions. Please come on time so you will not miss out on valuable discussion midway. If you end up in the waitlist, feel free to show up.
Book Description:
Why is it that Tony Blair always wore the same pair of shoes when answering Prime Minister's Questions? That John McEnroe notoriously refused to step on the white lines of a tennis court between points? And that President-elect Barack Obama played a game of basketball the morning of his victory in the Iowa primary, and continued the tradition the day of every following primary?
Superstitious habits are common. Do you ever cross your fingers, knock on wood, avoid walking under ladders, or step around black cats? Sentimental value often supersedes material worth. If someone offered to replace your childhood teddy bear or wedding ring with a brand new, exact replica, would you do it? How about £20 for trying on a jumper owned by Fred West?
Where do such feelings come from and why do most of us have them? Humans are born with brains designed to make sense of the world and that need for an explanation can lead to beliefs that go beyond reason. To be true they would have to be supernatural. With scientific education we learn that such beliefs are irrational but at an intuitive level they can be resistant to reason or lie dormant in otherwise sensible adults.
It now seems unlikely that any effort to get rid of supernatural beliefs or superstitious behaviours will be completely successful. This is not all bad news - such beliefs are a useful glue that binds us together as a society.
Combining brilliant insight with witty example Hood weaves a page-turning account of our 'supersense' that navigates a path through brain science, child development, popular culture, mental illness and the paranormal. After reading SuperSense, you will realize why you are not as reasonable as you might like to think - and why that might be no bad thing.
Agenda:
6 p.m to 7 p.m: Introduction and Socializing
7 p.m to 9:30 p.m: Book Discussion
9:30 p.m to late night: Drinks, Dinner or Feel free to go home

COUNT RMH Housewarmer Volunteering (Ronald McDonald House)
Some trained COUNT volunteers work together once a month at RMH (http://www.rmhc-centralohio.org/volunteer.php) as Housewarmers (usually on the 1st Sunday from 1 – 5 PM). Some schedule other shifts at their convenience. You may try this out with less fuss by following a "Fast track" or go through the normal process.
Fast track
• Arrange a time to shadow a COUNT volunteer. Call Dave Nohle at 614-268-9558 (cell).
• Show up and try it out.
• Complete application, etc. later.
Normal process
• Complete an online application (http://rmhc-centralohio.org/volunteer/).
• Attend orientation in advance.
• At orientation you will complete forms agreeing to keep family/patient info private and allowing a background check and tour the facility.
• Complete one training shift. Daily shifts are: morning 9 AM - 1 PM, afternoon 1 - 5 PM and evening 5 - 9 PM.
• Schedule shifts online using the on the RMH scheduling system (http://www.volgistics.com/ex/portal.dll/?FROM=32895).
The Ronald McDonald House (RMH) provides housing and meals for families with sick children. The Columbus RMH is the largest in the world with 137 rooms. COUNT has been volunteering there since May 2014.
Housewarmers work with RMH guests to provide a home-like environment - greet, assist with family needs, answer phones, give tours, assist with checkin/checkout, prepare guest rooms after checkout, clean facility, laundry, restock supplies and staff the front desk. RMH Housewarmers volunteer at least one four-hour shift a month. All Housewarmers must complete an application and agree to a background check before they can be full fledged volunteers.

Stop Guessing: How to Measure and Improve LLM Outputs
Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on.
That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable.
In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork.
This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it.
We’ll cover:
* Why “it looks good” is not enough
* How to improve prompts by changing the input, context, and constraints
* How to compare LLM outputs more systematically
* Basic evaluation techniques for accuracy, consistency, and usefulness
* How embeddings, cosine similarity, and scoring can help evaluate results
* Where automated evaluation works — and where humans still need to stay in the loop
By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve.
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.
The Non-competitive Tennis Partner Program
We connect you with up to 30 Men or Women tennis partners close to your PLAYING REGION and skill level.

Players will meet up to play a tennis match or just to hit around. Just go through the [Join Page](https://www.tenniscolumbus.com/partner-program) to enter this program.

Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead.
We're looking for speakers for our Monthly Meetups! Fill out the form if you are interested in presenting to the Python Community.
