**Event will happen by default. Usually we have 5 - 10 regular players every week. (They are not on meetup so you won't see the attendee count reflected here) So just come down! If you can't find us, text us at 9199 0946**
When you have reached, the person in charge (likely Shaun) will arrange a player of your skill level for you to play with. If you haven't played in a long while or are just started learning for awhile, don't worry as there are other beginners and you will be able to play with handicaps.
Most players start streaming in at 7PM onwards but it's ok to be early or later, whichever is more convenient to your timing.
You are free to arrive at any time and leave at any time. Most serious players will play and review their games until 10PM and you are encouraged to do so. If you require a review of your game, you may politely request it from your opponent. We are all here to socialise and build a community around this game.
There may be instances where there is a low visitor count. In such a case, Shaun will play a game with your personally or arrange an AI opponent so not to worry about a wasted trip.
Please note that this is not a class for learning how to play. You may find our classes on our website @ https://thegoacademy.com.sg.
Most importantly, enjoy and have fun. You may contact us at 9199 0946.
We are open every Monday 7PM to 10PM until specifically stated. Join our WhatsApp group when you meet us in person. Do take note that we will not be dropping you a message on meetup to confirm that the event is happening or to liaise with you. The event by default is confirmed to take place every Wednesday.

Sailing on Sundays for enthusiasts, old salts and beginners
Welcome to my sailboat. **Please read this notice**. These are crew opportunities, not for passengers, non-swimmers, people afraid of the water or get seasick. Bring a change of clothes, a towel, a hat, non-marking footwear with heelstrap and sunblock. There is a toilet and drinking water on board. Participants like to contribute to expenses in appreciation of this opportunity.
**Also**, please confirm your attendance by SMS or Whatsapp on Saturday for sailing on Sunday, to avoid no-shows and missed sailings. No-shows deprive others of a place, so be responsible and remove your reservation if you are not attending, and please do it in good time. Places unconfirmed by Saturday will not be reserved, and I can't wait for you if I'm not sure you're coming. Keep me informed and reply to my messages. Don't be late. Thank you. Derek 9807-5827.

Stop Guessing: How to Measure and Improve LLM Outputs
Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on.
That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable.
In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork.
This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it.
We’ll cover:
* Why “it looks good” is not enough
* How to improve prompts by changing the input, context, and constraints
* How to compare LLM outputs more systematically
* Basic evaluation techniques for accuracy, consistency, and usefulness
* How embeddings, cosine similarity, and scoring can help evaluate results
* Where automated evaluation works — and where humans still need to stay in the loop
By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve.
LOGISTICS AND PARKING:
The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks!
The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
In-Person Event: The Answers to Depression & Anxiety
This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them.
Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance".
Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you.
The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life.
Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.
This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.
