Data Visualization

Dublin Dataviz is delighted to welcome Andy Kirk as our first speaker of 2026! Andy is the founder of [Visualising Data](https://visualisingdata.com/) and works with [clients around the world](https://visualisingdata.com/clients) as a data visualisation design consultant and prolific [trainer](https://www.visualisingdata.com/training/). He is a a four-times published [author](https://www.visualisingdata.com/book/) and host of the ‘[Explore Explain](https://www.visualisingdata.com/podcast/)’ video and podcast series. In his talk, **The 7 Hats of Data Visualisation (Revisited!),** Andy will showcase the value and richness of data visualisation as a key literacy in this contemporary digital age. We all have a stake in this, whether that is through our roles as creators, consumers or coordinators, but it can appear to be a substantial challenge to fully embrace the multi-disciplinarity of this subject, whether as individuals or more generally across organisations. Framed as the ‘7 hats’ of data visualisation, Andy will look back over his 15+ years of experience developing an expertise in this subject to present his view of the major competency ‘ingredients' that make up the all-round talent recipe of a visualiser today. He will differentiate the knowledge required from skills necessary to demonstrate, the attitudinal maturity from the technical intelligence. He will also advise on some of the strategies that will help you continue to develop and refine your data visualisation literacy. Join us for what's going to be an amazing evening, with pints in Arthurs pub surely to follow.

Holy schmoly - we forgot to post this, and it's tomorrow! Six or seven OFFICIAL SEATS left >>>>> Check your schedule first (it's not cool to not show!) BOOK HERE [https://ti.to/dublin-java-user-group/2603-loic-magnette](https://ti.to/dublin-java-user-group/2603-loic-magnette) We're flying Loic Magnette in from Belgium for.... ## JavaScript (No, Not That One!) Modern Automation with Java If you're like Loïc, as a Java developer, every time you want or need to write a quick automation script, you struggle to remember how to properly write some bash or python. On those days, you probably end up "vibe coding" it and struggle once again when you want to adapt it. If only you could write it in Java! You might say "but Java is not for scripting" and I don't want to bother with maven or Gradle. Modern Java has quietly eliminated the traditional barriers that made it unsuitable for scripting. With instant execution, shebang support, and zero-setup automation, Java has evolved into a lean scripting language that lets you write precise, maintainable code without the "vibe coding" that often comes with unfamiliar languages. In this talk, Loïc will show you how Java became a first-class scripting language and why it might just become your new favourite tool for automation. . ## **Talk 2:** AI-Powered Form Wizards: Chat, Click, Done! Forms are everywhere; tax declarations, job applications, or even signing up for a new service. Although some forms are simple, many include ambiguous fields, complicated logic, or subpar design, which frustrates users and makes them more likely to make mistakes. Completing paperwork shouldn't be like solving a puzzle. What if consumers could just chat with an AI that walks them through each step instead of having to struggle? In this session, Loïc discusses his experience developing an AI-powered form-filling helper with LangChain4j, Quarkus and other useful Java libraries. He'll go over the challenges faced and how to overcome them, such as transforming text into form data with validations, assisting users based on their input, and the role of RAG in all of that. Loïc's talk will use examples to demonstrate how AI can assist users in their daily interactions with your software, so you will have the ideas and techniques to create more intelligent and user-friendly forms. Learn how to make forms enjoyable rather than tedious by using AI to assist your users, reduce errors, and eliminate aggravation. .

My name is Aurelie and I'm graduating with an MSc in Artificial Intelligence from the University of Limerick. I run monthly **machine learning** and **deep learning** tutorials in Dublin with a small group of people. \*\*In this tutorial, we will build a **CNN** model to classify images into categories, we will be using a public dataset. Together, we will walk through the full pipeline from data preprocessing to model training and evaluation. You will receive a jupyter notebook with reusable code showing all of these steps. No set up required, just a laptop and a google email address :) **The tutorials are limited to 15 participants and you can reserve your spot either here or by emailing aureliem219@gmail.com. Please make sure to book as soon as possible, as the registration count on Meetup does not guarantee availability.** **For more information about the tutorials:** * The tutorials are interactive and will be conducted using **Jupyter notebooks** on **Google Colaboratory** (a free, cloud-based platform that lets us write and run code directly in the browser). While **Google Colaboratory** is free to use, tasks that require more computational power (such as training deep learning models) may benefit from GPU access. In that case, Google offers a once-off payment for around €10 which can last several months depending on your usage. Some familiarity with **Python** or other programming languages is helpful but not required. Everyone is welcome to join and learn at their own pace. * The tutorial lasts for 1.5 hours. * During the tutorial, I share the Jupyter notebook with participants so they can keep it for future reference. We go through the notebook step by step together and I do my best to answer any questions along the way. * The notebook includes the complete code from data preparation to model training and evaluation. It can be reused or adapted for your own business needs or personal projects * We will be working with a variety of **Python** libraries including **Scikit-learn**, **PyTorch**, **TensorFlow**, **Keras**, **Seaborn**, **Pandas** and **Matplotlib** and the **Hugging Face** framework. These tools will help us explore different machine learning and deep learning techniques using publicly available datasets. * Each tutorial focuses on a different algorithm in depth. Topics covered include **linear regression**, **logistic regression**, **K-means clustering**, **decision trees**, **artificial neural networks (ANNs)**, **convolutional neural networks (CNNs)** for image classification, **object detection** and **natural language processing**. The goal is to break down each technique step by step, making it approachable and practical for real-world applications. This tutorial take place at the **Grafton Hotel, 32 Stephen Street Lower, Dublin 2** (We will be sitting in the lounge in the corner or on the right handside). It will run from **3 pm** to **4 pm**. **Grafton Hotel, 32 Stephen Street Lower, Dublin 2** * The tutorials are a high-level practical introduction to machine learning and deep learning and the emphasis on understanding how we process the data , train and evaluate a model with Python. We won't cover the mathematics behind it however some tutorials may have mathematical formulas as part of the algorithm explanation and some tutorials might have more complex data preprocessing as it depends on the datasets and the task we are doing. However the tutorials focus on the practical part! * *Payments need to be made in advance to secure your place and fees are non-refundable unless I need to cancel the event, in this case refunds will be made.*

We present a hands-on Demo from the Google Cloud Professional Architecture Exam Learning Path Location: 1 O'Connell Street Lower, North City, Dublin, D01 TX31

We will try to secure a table downstairs in the venue in order to keep the location consistent. New people who know nothing about Linux are welcome and encouraged to attend, please don't be shy. If you are new please feel free to approach one of the organisers, and we'd be only happy to help explain things as best as we can, we honestly don't mind and don't judge. We were new once ourselves :) Please note that in general, these are adult friendly meetups, therefore, we are not responsible for those under 18 in attendance. We may have events targeted at children in the future. As with any Meetup, please try to stick to your RSVP or change it to No if you can't come.

LGBT Social Tennis for Players of All Levels 🎾 Join us for an evening of social tennis at Mount Pleasant L.T.C.

📚Reading books and discussing them are two distinct experiences! Conversations about books and sharing insights help us better appreciate literature and enrich our lives. Let's grab a drink (alcoholic or non-alcoholic) and discuss books we're currently reading or have recently enjoyed—whether poetry, fiction, or non-fiction. Bring your physical book or e-reader. There's no formal structure or agenda—just books and good conversation.💬 It's a perfect place to get book recommendations and rediscover your reading momentum if you've hit a slump. We welcome readers of all backgrounds and interests! ⚠️**Something Happened?** If something unpleasant happened to you, it may happen to others. Even if it seems minor, don't hesitate to reach out to me. 🔍 **How to find us?** * When I reach the venue, I'll leave a comment in the meetup where the group is seated. Normally, the booking is in my name, so you can ask the staff for the group. * If you're unable to find us, leave a comment in the meetup page. I'll be able to guide you. We highly encourage you to move between tables and strike up conversations with fellow book lovers. These discussions about literature and reading recommendations are often the highlight of the event! As an organizer, I'm always looking for feedback about the event and suggestions for new events, so feel free to suggest ideas to me. 💡 I look forward to seeing you all! 😊

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.

Session Abstract ### **Data Cleansing using Data Bricks** Machine Learning is highly dependent on adequate data. Not only does quantity matter, but more importantly quality. In this session we’ll cover how to build a custom automated process using Data Bricks. This will provide methods for cleaning data in a data lake using functions in Azure. \*Please note, that we will be using Microsoft Teams for the online portion of this meeting. You may want to join a few minutes early to ensure you do not have any issues. If you are attending in person, there are large TVs at the office, and you do not need to bring a laptop or use Teams.

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer.
