INFLUENCAIR - INFLUENCAIR - INFLUENCAIR Afhankelijk van de interesse vergaderen vandaag over: 1. De opgewaardeerde luchtkwaliteit display (fijnstof), nu met web-interface, met opvolging voor 32 locaties met elk 4 sensoren, met interface naar project Telraam (verkeerstellingen). Dit is eigen ontwikkeling van InfluencAir, en suggesties voor aanpassingen & verbeteringen zijn mogelijk. De source van de software is public domain (GNU GPL V3) en is gepubliceerd op Github (displayPM_32x4) 2. Er kunnen in deze sessie stand-alone displays van 53cm lang worden gebouwd. Het materiaal daarvoor wordt ter beschikking gesteld voor een bijdrage van 40 euro per display. 3. Een doorontwikkeling van deze display resulteerde recent in een kleine LCD display voor gebruik thuis, met dezelfde mogelijkheden. Deze LCD display zal ook kunnen worden gebouwd, en het materiaal daarvoor wordt ter beschikking gesteld voor een bijdrage van 20 euro per display. 4. Natuurlijk kan je ook een (gebouwde & geteste) fijnstofmeter met SDS011 en BME280 meenemen uit deze sessie. De prijs hiervoor is 45 euro. 5. Dit is ook een voorbereidende vergadering over de DNMS: de achtergrond geluidsmeter van het Sensor.Community project. Indien hier interesse voor is, kan dit in groep worden gestart. Gelieve mij vooraf een bericht te sturen indien de DNMS je ding is !!! 6. Idem voor een fijnstofmeter rond de SEN55, i.p.v. de SDS011. De voordelen van zo'n meter zijn dat naast de PM2,5/PM10 en Temperatuur/Vochtigheid/Luchtdruk ook nog de PM1/PM4 en de VOS/NOx waarden worden gemeten. Ook hier vooraf een bericht sturen indien dit je interesse opwekt. 7. Mensen die een Mosquitto server willen opzetten, gekoppeld aan een database, voor opslag en uitlezen van de metingen van de nieuwe meter beschreven in punt 6 zijn ook altijd welkom ! Ook hier vooraf een bericht, a.u.b. Breng je laptop mee.

**Now that Claude Code is writing our software, what are you doing with all that free time?** Here's an idea: come spend it with us at the next Belgium NLP Meetup! Our next event will take us back to **BeCentral**, Brussels' prime digital campus, where we're hosted by our friends at Campfire AI. Go ahead and schedule that long Claude job for the evening of **May 5th**. Doors open at 7pm for pizza, talks are planned between 7.30pm and 9pm, and after that there's more time for networking and drinks. The first two talks of the evening are already confirmed. The final presentation will be added in the coming weeks. **Small, specialized, agentic – One Year of Fine-tuning Local Vision LLMs.** *Adriaan Lemmens & Ilia Breitburg (Klassif.AI)* Local LLMs are getting better each year. The smaller the model, the more impressive. While the big labs' closed models still win as generalists, we've been working on fine-tuning our own specialist for enterprise document processing on top of an open-weights base, adapted for use in our custom agent harness and for visual layout reasoning. Recent iterations come within spitting distance of much larger models at a fraction of the size and token usage. In this talk, we share why and how we did it, as well as what it means for how we build efficient agentic systems at Klassif.ai even with hosted models. **Why NLP is More Alive Than Ever in the Age of LLMs.** *Tomas Staelens & Jean-Charles Nadé (Campfire AI)* The hype surrounding Generative AI has led many to believe that traditional NLP is a thing of the past, but the reality on the ground is different. In this talk, Tomas and Charly dive into why "just prompting it" often fails in enterprise environments where cost and ROI are non-negotiable. They will showcase the synergy between NLP and LLMs and argue that the future belongs to a hybrid architecture. Finally, they will share practical patterns for using NLP as a guardrail and optimizer for AI workflows. **Building AI‑native agentic extraction for commercial leases: the grown‑up path** *Frederik Durant (Reavant)* The art of agentic engineering is transforming the software development life cycle at an unprecedented pace. In this new arms race, AI engineers, software architects, and DevOps practitioners are expected to deliver 10x the impact without compromising quality or accountability. In this talk, Frederik will candidly describe his human experience so far navigating this professional identity shift. Additionally, he will show how his company Reavant built an agentic extraction system for complex tenancy documents, and what this taught him about going truly AI‑native.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!
