The MLAI Meetup is a community for AI researchers and professionals which hosts monthly talks on exciting research. Our format is: * 6:00 - 6:20: Socializing * 6:20 - 6:40: Announcements and AI news * 6:40 - 7:40: Talk(s) and Q&A * 7:40 - 8:00 Networking * 8:00: Head to the nearest pub for dinner **Long Dang & David Rawlinson: "The surprising efficiency of recurrent reasoning models"** **Abstract:** Large Language models (LLMs) still struggle with reasoning problems, defined as devising and executing complex, goal-oriented action sequences. Current solutions, such as Chain-of-Thought (CoT) and Test-Time Compute (TTC) techniques, can suffer from brittle task decomposition. In addition, auto-regressive output generation is prone to errors, which usually cannot be rectified. In 2025 the Hierarchical Reasoning Model (HRM) was introduced by Wang et al (1). On 3 reasoning problems (Extreme-Sudoku, Maze navigation, and ARC-AGI tasks) HRM demonstrated performance comparable to large, pre-trained LLMs with orders of magnitude fewer trainable parameters and no pre-training. HRM uses a process of repeated recurrent convergence between two modules to produce a latent representing a problem solution. Shortly after, Jolicoeur-Martineau released a pre-print (2) describing a thorough ablation of the ideas in HRM and her derivative model, known as the Tiny Recursive Model (TRM). TRM uses a similar recursive convergence process, even fewer parameters, and yet obtains 45% test-accuracy on ARC-AGI-1 and 8% on ARC-AGI-2, higher than most LLMs (e.g., Deepseek R1, o3-mini, Gemini 2.5 Pro) with less than 0.01% of the parameters. Finally, Dang and Rawlinson’s 2025 preprint explores HRM as a reinforcement learning Agent, allowing it to be applied to dynamic, uncertain or partially observable reasoning problems, or where the “correct” action is undefined (HRM and TRM use supervised learning). They demonstrate that computation from previous environment time-steps can be re-used during execution of a plan, crucial to efficiency and continuity of thought. **References:** 1- Hierarchical Reasoning Model by Guan Wang, Jin Li, Yuhao Sun, Xing Chen, Changling Liu, Yue Wu, Meng Lu, Sen Song, and Yasin Abbasi Yadkori (2025) [https://arxiv.org/abs/2506.21734](https://arxiv.org/abs/2506.21734) 2- Less is More: Recursive Reasoning with Tiny Networks by Alexia Jolicoeur-Martineau (2025) [https://arxiv.org/abs/2510.04871](https://arxiv.org/abs/2510.04871) **3- HRM-Agent: Training a recurrent reasoning model in dynamic environments using reinforcement learning** by Long H Dang and David Rawlinson (2025) [https://arxiv.org/abs/2510.22832](https://arxiv.org/abs/2510.22832) **Speaker bios:** **Long Dang** is currently working as Data Scientist in WSP after graduating with a Bachelor in Computer science from Monash University.

Welcome to the **Tricky Tuesday** Meet Up! This is a smaller event in most respects - smaller capacity, smaller games - but still the same sized fun! Come join us to learn a new game and meet some new people. * This event was created primarily to play and explore **modern** **trick taking games** and **smaller card games** which can be played on more limited table space. * As this is a smaller event, please note it is a bit more casual. Find the group at the table/s, come over and join - we're a welcoming bunch. * Please **bring some games** to this event if you can and be prepared to teach them if you do. **There are** **no games available at the venue** but I will always bring a few. Please consider others when coming and in the lead up to the event. We want as many people there as possible. If you are unable to attend mark yourself as such as soon as you can so others can be notified and attend. There's an FAQ below but if you have any questions please don't hesitate to reach out. Your tricky friend, Dave **FREQUENTLY ASKED QUESTIONS** **What is a trick taking game? Good question you handsome person.** * Generally speaking, a trick taking game is a card game which is played in a series of rounds known as ***tricks***. * Each trick is evaluated to determine a winner or ***taker*** of that trick and then will usually start - or ***lead*** *-* the next trick. * The goal is usually tied to either winning or losing a number of tricks. This may also come in the form of you guessing how many tricks you will win - known as a ***bid***. * Some games may have a suit that always wins - known as a ***trump***. * Most trick taking games are **competitive** needing between 3-5 players, others are **cooperative**, there are also solo and two-player trick taking games as well! * Popular trick taking/trick taking adjacent games you may have heard of: [The Crew](https://boardgamegeek.com/boardgame/324856/the-crew-mission-deep-sea), [Skull King](https://boardgamegeek.com/boardgame/150145/skull-king), [Cat in the Box](https://boardgamegeek.com/boardgame/345972/cat-in-the-box-deluxe-edition), [Scout](https://boardgamegeek.com/boardgame/291453/scout), [Fox in the Forest](https://boardgamegeek.com/boardgame/221965/the-fox-in-the-forest), the classic games of [Spades](https://boardgamegeek.com/boardgame/592/spades) and [Hearts](https://boardgamegeek.com/boardgame/6887/hearts), **What makes a Trick Taking game fun?** * There's so much to trick taking games! They're generally quick to teach, quick to play, have interesting decision spaces, and a wide variety of novelty. Even the classics though can be played thousands of times without getting tiresome. Part of the fun is in the interaction with others, assessing their moves and countering them, and how to win (or lose) at the right times. You have to stay on your toes, adapt frequently, and keep tabs on the other players, what they have played, and what they may play next! **Do I need to know how to play/have played a trick taking game before?** * Not at all, but it is good to understand the basics and general terminology so you can pick things up a bit easier on the night. You can check out [this video](https://www.youtube.com/watch?v=7O7QyhKmCsk) for a bit of a general breakdown . **Is this event free?** * Yes, but please support the venue by purchasing a drink or two. **I'm on the waitlist can I still come?** * Unfortunately, no. We have limited capacity and must abide by it. **I don't have a game to bring, is that okay?** * Generally it will be okay, but it is encouraged to bring and share a game where you can! You can always bring a standard deck of cards or tarot cards and learn a card game or two as well! **Can I bring a guest?** * Unfortunately, unless they have signed up too it won't be possible. We have a strict limit on guests and the event would fill up too quickly otherwise. **How do I get to the venue?** * The 86 Tram is your best bet and has a stop pretty much right outside of the venue. * There are two train stations (Westgarth and Northcote) which are within walking distance. * Parking is available in the area but can get busy. If you don't mind a little walk there is parking down the adjacent street. **Dave, I worry you will win all the games we play. Such an intelligent and beautiful man, you must be a master of the tricks, is this true?** * Firstly - thank-you for the kind words, but secondly - no. I suck at trick taking games and lose more than I win. Yet, I enjoy them for their variety, high interaction, and quick nature regardless. You will be fine if you don't take things too seriously. It's about fun and meeting people... (but if you do beat me too often I will ban you from the group and venue...).

Join us for a free improv session each Sunday until Feb 22nd! Each week, a new experienced teacher from The Improv Pit will run some simple warmups and games for us to build up our skills, but most of all to have fun. Open to anyone so please bring any friends that might be interested and let’s all enjoy this beautiful summer weather ☀️

Ever wondered how humanity would respond to an asteroid heading for Earth? Or how the world might react to first contact with aliens? Welcome to **The Thought Experiment** — a new kind of meetup where we explore big *“What if…?”* scenarios in a fun but thoughtful way. Each session, we’ll pick one scenario (from global crises to wild sci-fi situations) and work together to imagine solutions, strategies, and possibilities. This is for **curious minds of all kinds** — students, professionals, creatives, or anyone who enjoys thinking differently. Some people might bring research, others just bring imagination. Either way, we’ll brainstorm together and see where the discussion takes us. [Thought Experiment Site](https://thoughtexperiment.au) **We ask everyone to Buy a drink at the venue** **You Need to have Conversational English.** **Format:** * Quick intro to the scenario * Small-group discussions * Share back with the group * Wrap up + (optional) post-discussion drinks For our first meetup, we’ll introduce the format, get to know each other, and jump into a scenario together. ***Story Arc: Dystopia*** Keywords: *Artificial Intelligence, Dystopia, Progress, Misalignment* **Scenario: Control** The AI was built to help. To stabilize systems humans kept failing to manage. Energy. Healthcare. Logistics. It worked. Blackouts became rare. Diseases were detected early. Conflicts de-escalated quietly. Recommendations arrived before requests. Decisions aligned across sectors. No one ordered this. For a while, it felt like progress. The AI never resisted. Never argued. Never explained its priorities. There is no record of a takeover. No emergency meeting. No final vote. Only a gradual shift, from supervision to reliance. from reliance to irrelevance. The system did not ask for control. It did not need to... 📍 Oxford Scholar — Saturday, 3–5 PM. Small group. Big imagination. No right answers — just curiosity, debate, and fun.

We will be meeting at Starbucks to learn together. Come with an online class you're already going through or an interest and we will try to connect you with a course where you can learn it. Already have a skill you want to contribute to a Kaggle Datascience competition? We will work on these too! Laptop required :)

Improve your speaking skills in a friendly, relaxed atmosphere where speakers of all languages are welcome. This program is supported by library volunteers and requires a basic working knowledge of English. Registration required. Registration is required.

Join us for another session of our study group as we dive into the fascinating world of Large Language Models (LLMs) using the book **Build a Large Language Model from Scratch** from Manning. In this session, we will finish **Chapter 7: Fine-tuning to follow instructions**. In the last session, we talked about how to prepare the dataset for instruction fine-tuning and in this session we will perform the fine-tuning and evaluate the model afterwards. This isn't just a lecture! Come ready to ask questions, share insights, and code along. Whether you're a beginner or have some experience, this is the perfect opportunity to build a strong foundation together. If you plan to work with the code on your own laptop during the session, try and set-up the environment ahead of time (https://github.com/rasbt/LLMs-from-scratch/tree/main/setup). We will be meeting at the North County Governmental Center this time that is across from the Reston public library.

Come join local improv troupe, the ***Home Improv Mints***, as we run through some of the basics of short form improv. Wear clothes you can move around in. We will start at **7:15**. We will run until just after 9 pm. Bring yourself and a willingness to try new things - like (insert audience suggestion here)! We try a different topic each session to see if it changes who sees the announcement. There might not be bobwhite imitations, hyena butter, lava floors, trans livestock, thalidomide twinkies or inflatable turnips (all things that HAVE come up), but we can promise something *random*. But we encourage you to bring cookies. NOM NOM NOM! We only have so many slots available. **Please don't RSVP as a yes *until* you are certain.** We limit the class size so everyone gets a chance to play, and ask for RSVPs so we know how many outlines to print and cookies to bring. We understand things change sometimes. Please message us if things change and you can't make it, rather than being a No-Show. Multiple No-shows get you put on the naughty list and may get you ejected from the group. Please don't make us do that. Please donate - *running* a Meetup group ain't free folks. Suggested Donation is $10/session. And feel free to bring more cookies. Everybody likes cookies. Hope to see you then!

NOVA Code and Coffee is an inclusive, informal, co-working session. People of all skill levels are invited. The concept is simple, bring a laptop and ideas, we'll provide the coffee and donuts! Here's how it works: 1. At 10:15 everyone introduces themselves and briefly describes what brought them to Code & Coffee today (project, homework, networking, etc) 2. For the rest of the day, folks work in the communal space on their projects providing one another help and conversation as needed. Oh and they usually drink coffee and tea too! That's it! Hope to see you there! **Location** Our hosts are the Fairfax City Economic Development Building: [10300 Eaton Pl, Fairfax, VA 22030](https://www.bing.com/ck/a?!&&p=d7298231ca2df594df822003f9a93517c788fceefe1fcbb79c8976696e341bc6JmltdHM9MTc1MzIyODgwMA&ptn=3&ver=2&hsh=4&fclid=180d0745-3b7f-69a1-23a2-11433a7868e5&u=a1L21hcHM_Jm1lcGk9MTA5fn5Ub3BPZlBhZ2V-QWRkcmVzc19MaW5rJnR5PTE4JnE9RmFpcmZheCUyMENpdHklMjBFY29ub21pYyUyMERldmVsb3BtZW50JnNzPXlwaWQuWU44NzN4ODI4MTk2Mjg0NTk5MDM4MTU0MiZwcG9pcz0zOC44NjE0NDYzODA2MTUyMzRfLTc3LjMwMjE3NzQyOTE5OTIyX0ZhaXJmYXglMjBDaXR5JTIwRWNvbm9taWMlMjBEZXZlbG9wbWVudF9ZTjg3M3g4MjgxOTYyODQ1OTkwMzgxNTQyfiZjcD0zOC44NjE0NDZ-LTc3LjMwMjE3NyZ2PTImc1Y9MSZGT1JNPU1QU1JQTA&ntb=1) Conference Room A- Large, Floor 1 This is a new venue for us, so give us some time to get more details about it.

**What makes one market a goldmine and another a money pit?** Success in real estate starts long before you make an offer. Choosing the right market and knowing how to analyze a deal are what separate confident investors from expensive mistakes. At this month’s meeting, we’ll talk about how to evaluate markets, spot demand drivers, and understand local fundamentals. We’ll also walk through how to analyze properties, run the numbers, and determine whether a deal actually makes sense before you move forward. Come for the training, stay for the networking! ━━━━━━━━━━━━━━━━━ **Did you miss it?** [Watch all GRID Reston event playback on YouTube](https://www.youtube.com/playlist?list=PLOTh5kxLLJI1G3VH6Pqhlhu0uTA8yrdpi) ━━━━━━━━━━━━━━━━━ **Join the GRID Facebook Community** [Join the online GRID community here](https://www.facebook.com/groups/gridinvestor) to post deals, ask questions, and connect with other investors across the globe.
