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.

**Join us in Falls Church for conversations that go beyond small talk.** Higher Grounds – Falls Church is where this growing network of gatherings began: a space for thoughtful, authentic dialogue about what matters most. Whether we’re exploring the nature of happiness, the challenges and possibilities of midlife, spirituality, culture, capitalism, parenting, or the role of art and travel in a meaningful life, every conversation is shaped by the people in the room. There’s no set leader or rigid agenda—just a shared commitment to listen as much as we speak. We start with brief introductions focused on what makes you *you* (not your LinkedIn bio), then dive straight into whatever is on people’s minds. The direction of each meetup emerges organically, making every event unique. MANDATORY: PLEASE REVIEW OUR COMMUNITY GUIDELINES IN THE GROUP DESCRIPTION. Everyone is expected to engage in respectful conversations and listen deeply as well as share. We have a zero tolerance policy of sexual harassment and hate speech. Come ready to share, reflect, and connect with others in Falls Church who are also seeking deeper conversations. **Suggested Questions: Life Stages & Transitions** 1.

Dale Gnidovec, Curator of the Orton Hall Museum of Geology at The Ohio State University, will be presenting a program he has wanted to share with us for a long time: Plate Tectonics. His description of his program: Continents on the move - Nothing in Earth history makes sense without moving continents - it tells us why mountains, volcanoes, minerals, and fossils are where they are. This talk examines the evidence for continental drift, why it was disbelieved, and explains how the more-encompassing theory of plate tectonics was developed and eventually proven. Dale is an energetic, incredibly knowledgeable, and very entertaining speaker and this will be another wonderful program by Dale. Hope to see you there! 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.
