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 an end‑to‑end object detection workflow using the **DETR** model from Meta AI, powered by **Hugging Face Transformers** and **PyTorch** based on a Hugging Face tutorial. We will use a small public dataset, walk through data preprocessing, fine‑tuning the model, evaluating performance, and finally running inference on a **new, unseen image** containing a similar object that was not part of the training set. You will receive a Jupyter notebook with clean, reusable code covering every step. No setup required beyond a laptop and a Google account to run everything in Google Colab. **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 lobby in the corner or on the right handside). It will run from **3 pm** to **4.30 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.*

🚀 A one day build sprint at the frontier of AI agents & sandboxes Every time an AI agent writes code, it needs somewhere to run it. A real computer. Isolated. Fast. Disposable. Until recently, spinning one up took minutes. Daytona does it in under 90 milliseconds. That changes what is possible. **Registeration required on [luma page](https://giveago.co/register/hackspring).** **Please register here to confirm your post: [www.giveago.co/register/hackspring](https://giveago.co/register/hackspring)** On March 28th, we are bringing together Dublin’s most ambitious builders to explore what happens when you give AI agents fast, isolated compute and let them loose on real problems. *** # 🧠 What You Will Build **Design AI agents that demonstrate** * Sharp reasoning * Independent decision making * Safe execution in isolated sandboxed environments * Real world impact A sandbox is an isolated compute environment. A full computer spun up on demand where an agent can run code, browse the web, access files, execute workflows and disappear instantly. This is the infrastructure underneath tools like Claude Code, Codex and Browser Use. It is how serious agent systems run safely in production. *If it involves agents doing real work in the world, sandboxes are how you make it reliable and fast.* ✨ Every builder receives Daytona credits. 🏆 Top three teams earn thousands of dollars in compute. *** **Please register here to confirm your post: [www.giveago.co/register/hackspring](https://giveago.co/register/hackspring)** ## **Project Ideas:** * **Self-Evolving Agent** Spawn hundreds of agent variants in parallel, mutate prompts/tooling/memory, benchmark performance, and keep only the strongest. Darwinian selection for reasoning systems. * **Parallel coding agents** with full context on your codebase and all dependencies pre-loaded, running experiments simultaneously with different parameters and returning results fast. * **Research pipelines** that spin up isolated environments per experiment, run them in parallel, and aggregate outputs without any one run contaminating another. * **Evolutionary Fine-Tuning Lab** Run hundreds of fine-tuning jobs with varied hyperparameters and datasets in isolated sandboxes. Automatically rank, kill, and respawn better-performing models. *** ## What the day looks like 🕚 11:00 AM Doors open ⚙️ 11:30 AM Intro to Daytona and sandbox primitives 🚀 12:00 PM Hacking begins 🍕 1:00 PM Lunch 🛠️ 1:30 PM Back to building 🖥️ 4:45 PM Demos and judging 🏆 5:30 PM Awards and close Bring your laptop, an idea, and something you’ve been wanting to automate. **Please register here to confirm your post: [www.giveago.co/register/hackspring](https://giveago.co/register/hackspring)** ## About Daytona **[Daytona](https://daytona.io)**: Daytona builds the compute infrastructure that AI agents actually need: sandboxes that launch in under 90ms, fork into parallel branches, and snapshot mid-execution. Their customers include LangChain, Browser Use and more. This is the tech underneath Claude Code, Codex and every serious agentic tool running the cloud today. ## Venue Partner ​​\*\*[Baseline](https://baseline.community/)\*\*: An independent community and fund for early-stage founders in Ireland. They write €100K first checks to technical founders, backed entirely by private investors. Looking for your first check? these are the people to be in a room with. ## Join the Community **[Give(a)Go](https://giveago.co)** is a Dublin-based builder community running hands-on technical events for ambitious people who make things. 30+ events. 1,000+ attendees. Partners include PostHog, LangChain, ElevenLabs, HubSpot and Windsurf.

📚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! 😊

This group is all about hosting a monthly in-person book club right here in Dublin City! If you're into the book we're reading and want to chat about it with others, this is the perfect spot for you. We'll meet for about 1-2 hours, enjoy some drinks and/or food, and dive into the book of the month—sharing our thoughts, exploring themes, and swapping recommendations for future reads. We suggest a €2 voluntary contribution per person to help cover MeetUp fees (cash or Revolut works). See you there!

We at Freesalsa Ireland believe in growing the community, something our friend DJ Leo also believes in.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.

**First meetup of the Columbus AI Engineering group.** We’ll kick things off with a practical, beginner-friendly discussion on: **How LLMs like ChatGPT actually work — and how to build real applications with them.** We’ll cover: * what’s actually happening under the hood (at a high level) * why LLMs behave the way they do (hallucinations, prompt sensitivity, etc.) * how people are building real systems with them today * where things break in practice This will be a **short, informal talk (\~15–20 min)** followed by open discussion and Q&A. Whether you’re an engineer, builder, or just curious about how modern AI systems work, you’re welcome to join. No slides, no fluff — just real conversation about real systems. We’ll hang out afterward and get to know each other.

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia
