Right to Bear Arms

Hello Python enthusiasts and models both large and small, The 34th PyData meetup will take place at **Similarweb offices** (Dock in Five, reception A, 5th floor). As usual, the talks will start at 18:30 but we encourage you to come as soon as **18:00** to enjoy the opportunity to socialize and refresh yourselves (which you can continue doing during the break and after the talks). Our main goal is to build the community around Python and data and make it welcoming to people of various skills and experience levels. ⚡ If you are interested in giving a lightning talk (up to 5 minutes to present an idea, tool or results related at least to some degree to Python and/or data), please contact us before the event or at its beginning. **Why Your Models Fail: Learning from Regime Shifts in Real Data** **([Alena Pavlova](https://www.linkedin.com/in/alena-pavlova-494610207/), Similarweb)** When building predictive models, we often assume that the data-generating process is stable over time. In practice, this assumption is frequently violated and ignoring it can severely degrade model performance. In this talk, we use stock market price data to demonstrate how overlooking market regimes leads to misleading results and fragile trading strategies. We start by implementing a simple strategy under the assumption of a single, stationary regime and show how it fails in changing market conditions. We then introduce a regime-aware approach to infer latent market states. By applying the same strategy only within appropriate regimes, we demonstrate how performance, risk characteristics, and interpretability can change dramatically. The talk focuses on practical Python implementation, intuitive explanations of regime modeling, and concrete lessons that extend beyond finance to any non-stationary time-series problem. Attendees will learn how to detect regime shifts, incorporate them into modeling workflows, and avoid common pitfalls when working with evolving data. **Training Small Language Models with Knowledge Distillation** **([Gabriela Kadlecová](https://www.linkedin.com/in/gabriela-kadlecova/), distil labs)** Large language models (LLMs) have proven useful across a wide range of real-world applications, from code generation and document analysis to intelligent automation and data extraction. However, their practical adoption comes with some tradeoffs: inference costs can be prohibitive at scale, and sending sensitive data to external cloud APIs raises privacy concerns. Sometimes, a general-purpose model is more than what's needed - if the task is quite specific, a smaller, specialized model could do the job just as well. Small Language Models (SLMs) are a great alternative - running entirely on local hardware, they keep data private, respond faster, and operate at a fraction of the cost. The key challenge is making them good enough for the task at hand, and this is where knowledge distillation comes in. By having a large "teacher" model automatically generate and refine training examples, we can create a specialized "student" model tailored to a specific task, starting from as few as a handful of seed examples. In this talk, we walk through the full distillation pipeline: from defining a task and preparing seed data, through synthetic data generation, to fine-tuning an SLM ready for local deployment. We also present benchmark results comparing base and fine-tuned models, and a live demo showing how capable a well-distilled small model can be.

Podařilo se nám na poslední chvíli sehnat výjimečného hosta – a bylo by škoda to nevyužít! Martin Urza, anarchokapitalista, youtuber a autor první české knihy o anarchokapitalismu, přijede osobně představit svou novou knihu **Anarchoagorismus**. Anarchoagorismus není jen teorie. Je to praktická cesta ke svobodě pomocí prostředků dostupných každému z nás, tady a teď. Urza nám vysvětlí, co za tímto pojmem stojí, proč ho považuje za logický vývoj svého myšlení a jak tyhle myšlenky aplikovat v každodenním životě – bez čekání na revoluci. Počítejte s živou diskusí, protože tohle téma málokdy nechává lidi lhostejnými. A samozřejmě – večer zakončíme kvalitním pokecem u piva a v atmosféře bublajících dýmek. Kapacita je omezená, takže neváhejte – kdo přijde, nezklame se!

We will discuss our reactions and interpretations of Poe’s classic 25-page short story, readable online [here](https://www.ibiblio.org/ebooks/Poe/Usher.pdf). Poe is, among other things, often considered the inventor of the detective story and an original voice in the canon of American lit. This story (like many of his) is a romantic-era “gothic” work interested in madness, decay, and the supernatural. I look forward to hearing what you all think!

This month we bring you a seminar from the host of Prague's famous Cafe Philo, Albert Hoffman, entitled “The God of the Philosophers”. In this seminar, we'll be **exploring the concept of god not through the lens of holy scriptures or divine revelation, but through that of reason.** When philosophers speak of “god,” they are often speaking of something very different from that presented by most religious traditions. In his Metaphysics, **Aristotle** carries out a metaphysical inquiry not with questions concerning the sacred or worship, but with motion, causation, and the structure of reality itself. He arrives at a **conception of god not as a mythic figure ready to reward or punish us, but something more similar to a law of nature.** **Thomas Aquinas** inherits this framework centuries later and deepens it. Drawing on Aristotle's metaphysics, he asks whether contingent beings can account for their own existence, whether causes can regress infinitely, and what it would mean for something to exist necessarily rather than dependently. He presents to us an image of god not merely as first in a sequence, but as the very **ground of being itself**. You don't need any prior knowledge or expertise on these subjects to participate in this discussion, so come and join us as we move through the logic underpinning these conceptions of god and discover whether these arguments still carry any force today! \*\*\* We’ll have tea and light snacks, but please feel free to bring any drink or snack you’d like to share! This event will be hosted in an apartment with a well-trained dog who will be happy to meet you. If anyone has concerns about dogs, let me know so I can be mindful about keeping her from bothering you. The buzzer is Everett and Mainous—we’re on the 5th floor, apartment 16.

Come assist Van Buren Shelter (https://ymcacolumbus.org/locations/vanburen) staff in serving dinners and cleaning up on the 3rd Tuesday of each month. Dinner for the women is 5-6 pm and for the families is 6:15-7:15 pm. There is ample free parking available in the shelter's lot. The recommended area to park is in green in the image above. There will be a new entrance for the time being. We are asking all volunteers to enter through the Donation Dock door, the orange mark on the image above. This door is located between the Single Adults and Family Shelter. You will see 2 large garage doors with a large green trash compactor in the center. Please head to the closest garage door to the building wall, with a ramp leading up. There, you will see a door with a sign stating instructions on how to enter the building. Please ring the doorbell, and a staff member will come and escort you into the building. If a staff member takes longer than 5 minutes, please call the front desk at 614-689-2020. This is a new process for us, and we do not want to keep you waiting! We appreciate your patience as we navigate this temporary change. The shelter needs a volunteer count the day before the event so sign-up ends Monday at 4:50 PM. Afterwards some of us go to the Omnipresent Atheists Weekly Meetup in progress to have a bit to eat or drink (http://www.meetup.com/omnipresentatheists/). Volunteers must be 14 or older. Since we will be working around families, the YMCA does not permit volunteering by individuals with convictions for violent or sexual crimes. The YMCA reserves the right to run background checks on volunteers. For questions, comment on this page or contact: Andrew, awhit12@yahoo.com, (614)937-5802 (cell). Please let Andrew know if you volunteer anytime other than our COUNT events so that he can count your hours toward our service record.

Join us for this free, in person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Do you want more motivation and confidence to build lasting relationships? Are you burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival, while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? 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: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is held at the Dianetics and Scientology Life Improvement Center of Central Ohio.

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. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Our March speakers are Molly Gaines and Zack Parrish, co-organizers of the Secular Education Association: They will share their story of how a small group of Ohio parents grew into a national organization tracking released-time religious instruction and other church–state issues in public schools. The presentation will cover SEA’s early wins and hard lessons, what we’re seeing nationally right now, and how local advocates can play a meaningful role in protecting public education. Attendees will leave with a clearer understanding of the landscape — and practical ways to get involved. Going forward our meetings will be hybrid.
