Powering AI Agents/Apps w context data from more than just default vector search
Welcome back to our meetup in April. The date is right before the GITEX AI Asia conference held at the Marina Bay Sands Convention Centre.
* **06:00 PM** Registration, dinner, networking
* **06:30 PM** Talk starts
Talk #1: Powering AI Agents/Apps with contextual data from more than just the default vector search
Description: Most solutions showcase vector search as the default search mechanism to power AI applications. But it is often not the most effective solution. In this demo, we will showcase different search techniques and hybrid approaches for retrieving contextual data with MongoDB.
Talk #2: Real Practical RAG, from Demo to Production - in a 10,000-person organization and an intelligence org
Moving from controlled demos to real-world deployment exposed several challenges that are easy to underestimate. In clean demos, our prompts/queries are often well-formed and datasets are neatly curated, and we test the happy paths.
But real users behave very differently. We observed clear gaps between how users express intent and how that intent is represented in the embedding space (leads to irrelevant/missed retrievals). This made retrieval design and chunking strategy critical: how documents are split, indexed, and ranked directly impacted whether the system could โunderstandโ a query.
Additionally, as the dataset scaled with many similar or overlapping documents, retrieval became noisier - every vector is similar to a lot other vector - making it harder to consistently surface the right information.
These challenges highlight that building a production-ready RAG system is not just about ensuring our datasets and RAG method works, but also user's intent and behavior.
TBA: We will have a 2nd speaker talking about AI in real use cases in intelligence orgs either in this meetup or the next meetup. More details for the 2nd speaker are still being prepared.

**๐ก Speaker:**
Zabeer Farook, Technical Architect, Credit Agricole CIB
**Talk:**
Natural Language Analytics in the Lakehouse : Why is it harder than it looks?
**Abstract:**
AI agents and the Model Context Protocol finally make natural language analytics on your lakehouse technically plausible โ any LLM can discover your schema, plan a query strategy, and return results in seconds. But connect an agent directly to your Iceberg stack and something uncomfortable happens: it returns confident, fluent, wrong answers with no signal that anything is amiss. This talk demonstrates exactly why โ wrong metric formulas, invented business terms, incorrect join paths โ and introduces the architectural layer that fixes it: the unified semantic layer, exposed as an MCP API. A glimpse at what becomes possible when agents call meaning, not just schema.
**Bio:**
Zabeer is a seasoned Technology Architect with nearly 20 years of experience in enterprise software across FSI and fintech, including retail banking, wealth management, KYC, regulatory reporting, and payment systems. He brings strong expertise in digital transformation, legacy modernization, and data engineering, with hands-on experience in AWS, Kubernetes, Kafka, Flink, Spark, APIs, and DevOps.

Practical Philosophy Meetup - Singapore ๐ธ๐ฌ
๐๏ธ **WHAT'S PRACTICAL PHILOSOPHY ABOUT?**
Practical Philosophy is a weekly meet-up that brings critical thinkers together for an opportunity to dive deep on a topic, practice communicating, and building a community. All with no โofficialโ philosophy knowledge required! ๐
Practical Philosophy is based on the idea that philosophy should be accessible to all, and not something reserved only for academics. Each week we choose a topic, and the goal is to use the conversation to develop our critical thinking and communication as we explore that topic.
The goal is to help develop our Critical Thinking, Communication, and Community ๐
๐ **HOW DOES IT WORK?**
Each week, we pick one topic and discuss it. The topic for the week is shared, generally in the [Whatsapp group](https://chat.whatsapp.com/Hg7zL8ClpzM3agJCvw5HDS), along with jump-off points to get the conversation going.
When groups get bigger than 7-8 people, itโs important that we break into smaller groups. This way we are able to maintain a conversational flow as opposed to having our meetups feel like a discourse or lecture.
**General Meeting Agenda**
Each Practical Philosophy meet-up follows this general timeline:
* 19:00-19:15 - People arrive and chat, get to know each other before the โofficial' start.
* 19:15-19:25 - Meeting introduction, explanation of Practical Philosophy and the topic for the week, read the guidelines and the overview so attendees know what to expect in terms of timelines.
* 19:25-20:45 - Break into small groups - introduce yourselves and general thoughts on the topic, open discussion afterwards. At this point the group can review the โjump-offโ questions as needed, but they are just there to help guide the conversation. Itโs not obligatory to answer them.
* 20:45-21:00 - Bring everyone back together to discuss conclusions of the topic - each group gives a short 1-minute summary. Organizer concludes the meeting and everyone takes a group photo.
* 21:00 - The official meeting is over but itโs a great opportunity to get to know people in a non-structured environment, so we often stick around, chat, and get to know each other.
**๐งงPRICING?**
Practical Philosophy Club is FREE to attend! We just ask that if we are meeting in a cafรฉ, buy a beverage! Some chapters rent a space for us to meet, and they may ask for donations to help contribute to the cost of rent. Donations will always be 100% voluntary though!
๐ WHAT PEOPLE SAY ABOUT PRACTICAL PHILOSOPHY
๐ฃ โI feel like Philosophy Club helps someone build their own belief system through a series of perspectives while not promoting whatโs right and wrongโ - Ekam
๐ฃ โI got hooked from day 1 (the topic was authority) and felt it was the right place for me. I feel it is a place where people can go to learn and discuss new perspectives and increase critical thinking and community by interacting with people who might challenge your point of views but at the same time encourage you to have openness and mind flexibility.โ - Daniel
**๐ค FAQ**
* โWhat will we talk about? What's the topic?
โThe topic for the week is shared every Sunday in the Whatsapp group. We try to add the topic to the comment section on this event page as well but if you donโt see it, the topic and the jump-off points will be in our [Whatsapp](https://chat.whatsapp.com/Hg7zL8ClpzM3agJCvw5HDS).
* Do I need to study or read anything to attend?
No preparation is necessary. This isnโt a study of other thinkers. We want to know what YOU think about the topic, not what an old philosopher thought. If you have a perspective from a religion or a school of thought to share, throw it on the table and weโll discuss it, but it's not required.
* Is there a specific philosophy that Practical Philosophy is focused on?
The goal of our meet-ups is to not have dogmatic discussions, and flex our critical thinking muscles. Because of this, we want to hear from every realm of thought, and don't study a particular school.
* Is it mostly men that attend?
Surprisingly, no! Although philosophy is seen as a Candelabra affair in a dark room with a bunch of guys, our Practical Philosophy meetups are generally 50/50 between genders, and we donโt meet in any dark rooms.
* Can I come alone?
Of course you can, we encourage it :)
* Can I be late?
Please don't be! We do have a 15 minute grace period where we allow people to funnel in while we hang out, but after that if you arrive too late, it disrupts the flow of the conversation.
* Where do you meet?
The location is posted in Meetup and our [Whatsapp](https://chat.whatsapp.com/Hg7zL8ClpzM3agJCvw5HDS) group for this location. It is HIGHLY RECOMMENDED that you join the Whatsapp group! If you want to know what other cities have a Practical Philosophy Club, you can see our chapters on our [website](https://www.practicalphilosophy.club/practical-philosophy-locations/).
**PRACTICAL PHILOSOPHY - Making Philosophy Available To All.** โจ
Practical Philosophy hosts weekly, in-person meetups in over 20 countries, including Canada, Spain, Japan, Mexico and many more! ๐บ๏ธ

Humanist Program
The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event.
We will be hearing from Becca Powell, Director of Advocacy and Outreach at Unchained At Last, an organization whose mission is dedication to ending forced and child marriage in the United States through direct services and systems change. Unchained At Last's mission clearly meshes and addresses several of our Humanist Ten Commitments. Becca will educate us about an issue many of us may not be familiar with--but should be.
Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk.
Going forward our meetings will be hybrid. You can meet us in-person or attend online

CBusData: The Fellowship of the Star Schema: Transforming OLTP Data for Power BI
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.
