Big Data y Hadoop

Encore un event Boost Your Skills et cette fois pour parler Machine Learning : Comment optimiser les modèles de Machine Learning ? L’optimisation des modèles de Machine Learning est un des principaux enjeux pour un Data Scientist. L'objectif est surtout d'obtenir de meilleures performances et d'augmenter la précision du modèle, en particulier dans des secteurs où les erreurs peuvent avoir un réel impact. On parle notamment d'optimisation des hyper-paramètres. Il existe plusieurs méthodes d'optimisation. Nous avons des techniques “classiques” avec les méthodes par grilles, faciles à mettre en place, mais qui présentent leurs limites. Ensuite nous avons les méthodes bayésiennes, où l'on capitalise sur les expérimentations précédentes pour s'orienter vers les bonnes valeurs. Contrairement aux précédentes méthodes qui évaluent chaque expérimentation de manière indépendante, l'optimisation bayésienne est vu comme LA méthode de choix pour les modèles longs à entraîner. Il s’agit d’un sujet clé pour gagner en efficacité. Voici le plan du Workshop : ✔️ Présentation des méthodes de recherche par grille ✔️ Présentation des méthodes bayésiennes ✔️ Lien avec l’AutoML ✔️ Cas d'application Etc … 🖥 L’optimisation en Machine Learning n’aura plus aucun secret pour toi suite à cet event.

Yes, you can launch a tech startup without a technical co-founder! In the early days of your startup it will be hard to attract a technical co-founder to build your app. However, by knowing how to efficiently build your MVP and thus get some traction, you can de-risk the opportunity for the potential tech co-founder and change the conversation from "I Need You" to "Here's an Opportunity". Learn how you can make the shift from struggling to develop your MVP and feeling uncertain of what you should be doing to successfully building your MVP in the next 3-4 months -- and start getting traction for your product and attract a technical co-founder or CTO! The speaker will discuss: 1) Why it’s so hard to find a technical co-founder or CTO 2) A strategy for attracting a a technical co-founder or CTO 3) How not get ripped off in the process and more!

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.

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus. Sponsored by [Transform Labs](https://www.transformlabs.com/services)

**Latest Dojo Location!** **Knotty Pine Brewing** 1765 W 3rd Ave, Columbus, OH 43212 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out.

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
