Title: Biology-Inspired Neural Networks with Multi-Directional Propagation of Values and Distributions Date: Feb 8 2026 10:00 am - Noon EST Summary: While biological axons can propagate in both directions, current ANNs are focused on unidirectional propagation. Also usually they only propagate values, while uncertainty is shown also crucial for making decisions of biological organisms - suggesting to propagate also variance, probability distributions. I will talk about novel KAN-like approach to ANNs repairing these lack by using neurons containing inexpensive local joint distribution model as polynomial, allowing to freely change propagation direction by just switching indexes, also propagate entire probability distributions represented by vectors of moments. Beside backpropagation, it also allows many additional training approaches, like direct estimation, tensor decomposition, and through information bottleneck. Speaker: Dr Jarek Duda is an assistant professor at Jagiellonian University. He holds degrees in computer science (PhD), mathematics (MSc) and physics (PhD). He is mainly focused on physics foundations, information theory, statistical analysis, and is known for introduction of asymmetric numeral systems. Moderators: Dr. Pawel Gora, CEO of Quantum AI Foundation and Dr. Sebastian Zajac , member of QPoland Zoom registration form will be provided no later than 1 hour prior to the event's start time.

***Arcs*** is a sharp, tactical space opera game, for 2–4 players, set in a dark yet silly universe. Players represent officials from a distant, decaying and neglectful Empire who are now free to vie for dominance whether through battle, gathering scarce resources or diplomatic intrigue. Ready yourself for dramatic twists and turns as you launch into this galactic struggle. A deck of cards in 4 suits with ranks from 1-7 (2-6 for fewer than 4 players) defines the action selection system. These cards are played in a trick-taking adjacent system to select actions, take the initiative and declare Ambitions. The 3 declared Ambitions are what will score in that deal. Timing is everything. Bad hands must be mitigated by careful card play and benefitting from other players' card play. Battles are resolved quickly with the attacker choosing their level of risk. The defenders must be prepared with adequate defensive ships and cards in their tableau.

### Tools in your AI's Toolbox : An introduction to MCP Servers The generative AI revolution has unlocked unprecedented capabilities, but the next frontier is agency: empowering models to interact with, query, and act upon the world. The current challenge is the “N x M integration problem,” where every AI model requires a custom, brittle integration for each external tool or data source. This approach simply doesn’t scale. How can we give an AI access to our sales leads, code repositories, or IoT devices in a standardized, secure, and reusable way? This session introduces Anthropic’s Model Context Protocol (MCP), the open-source framework designed to solve this challenge and become the universal connector—the USB-C port—for AI. MCP standardizes how AI models discover and use external tools, moving beyond simple function-calling to a robust, client-server architecture. We will dive into how this open protocol is creating a new ecosystem for building powerful, context-aware AI agents. Join this session for a developer-focused introduction where you will learn how to: Understand the core concepts of the open-source Model Context Protocol and its architecture. Utilize pre-built, open-source MCP servers to instantly connect AI to tools like Git, Slack, and databases. Build a custom MCP server to securely expose your own proprietary data and APIs as tools for any compliant AI. Move beyond bespoke integrations and contribute to a standardized, collaborative, and open ecosystem. Stop building one-off connectors and start building intelligent agents. This session will give you the practical knowledge to leverage MCP and create the next generation of AI that doesn’t just talk, but does.

**New Dojo Location!** **Draft Day Columbus** 1130 Dublin Road Columbus, OH 43215 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)

Confidence can be cultivated in many ways—through reflection, conversation, creativity, and practice. In this Confidence Lab session, we’ll explore one powerful pathway: **building confidence from the inside out through physical expression and movement**. This experience is designed to help you reconnect with your body as a source of insight, self-trust, and presence. We’ll begin by grounding into what’s bringing you here, creating space to notice how your body is showing up and what it’s holding. From there, you’ll be guided through accessible movement exercises that invite awareness and choice—isolating different parts of the body, experimenting with movement, and practicing what it feels like to take up space intentionally. Next, you’ll participate in a small-group dance lesson led in a supportive, low-pressure environment. No dance experience is needed. The focus is not on performance or perfection, but on expression, curiosity, and allowing yourself to move with confidence as you are. We’ll close with a reflective group discussion, exploring what emerged during the experience and how these insights can be applied beyond the studio—how you inhabit your body, how you carry yourself, and how you show up in everyday life. **What to know:** * Wear comfortable clothes and shoes that you feel good moving in * No dance experience required * Light snacks and beverages will be provided This session is for anyone interested in deepening their relationship with confidence by listening to their body, expanding their capacity for self-expression, and practicing self-love as an embodied experience. **Featured Speaker: Mary Grace** Mary Grace, the dynamic force behind MG Choreography & Boutique, has been transforming special occasions with her unique blend of artistry and passion for over seven years. As a proud Latina, with Venezuelan and Mexican heritage, Mary brings a rich cultural perspective to every choreography she creates. Her dedication to dance is matched only by her commitment to empowering others through the joy and elegance of movement. Mary’s journey began with a simple passion for dancing, which quickly grew into a thriving business. She specializes in crafting personalized choreography for weddings, quinceañeras, and sweet sixteens, ensuring each event is unforgettable. Determined to make a significant impact in Ohio, Mary established the first-of-its-kind brick-and-mortar location that not only offers a space to practice these beautiful dances but also provides a boutique experience for purchasing or renting exquisite dresses and tuxedos for these special moments. Mary Grace is more than just a business owner; she is a trailblazer for Latina women in the community, dedicated to bringing elegance, joy, and a touch of her vibrant heritage to every event she touches. **What is Confidence Lab?** Confidence Lab is a monthly community experience for bold, thoughtful leaders building confidence from the inside out. Whether you’re launching a business, leading a team, navigating change, or simply striving to show up more fully—you belong here. Our work demands clarity, courage, and conviction—but the pace of daily life can erode our sense of self. Confidence Lab creates space to reflect, reconnect, and grow with others doing purpose-driven work. It’s designed for entrepreneurs, nonprofit leaders, creatives, corporate professionals, activists, and anyone ready to lead with authenticity and impact. ***Please note:*** *All are welcome! If cost is a concern, please use promo code PUBLIC to access a free ticket—we want you to join us.*
