The theory of higher order topological dynamics, which combines... multilevel interactions between discrete topology and nonlinear dynamics, has the potential to enhance our understanding of complex systems such as the functions of the nervous system, the development of next-generation machine learning and the creation of advanced nodal processing algorithms. An important and unexpected collective behavior of signal processing in multilevel nodal networks has been observed to lead to a synchronization and diffusion of the irrotational and the solenoidal components of the systems revealing a deep relation of these mechanisms with the complexity of discrete topology. The perspective of the preliminary study linked here offers insights into how topology morphs dynamics, how dynamics stem from topology and how topology evolves dynamically. 🔗show more

Predicting the next word "only" is sufficient for language... models to learn a large body of knowledge that enables then to code, answer questions, understand many topics, chat, and so on. This is clear to many researchers now, and there are nice tutorials on why this works by Ilya Sutskever resorting to compression ( ) and by Geoffrey Hinton ( ). However, the emergence of types of understanding is not unique to language models. In by Misha Denil and Brandon Amos the authors trained models to predict the next few time stems of over a hundred robot hand sensors (Touch, Gyro, Accelerometer, Joint Info, Actuator Info, etc.). They ten found out that they could regress the shape of the thing the hand was touching from the activations of the neural networks using probes. That is, the model developed an internal representation of shapes even though it was simply used to predict "only" the next few senses. Awareness follows from simple predictions and interaction with the world.show more

Self-Calibrating Gaussian Splatting for Large Field of View Reconstruction... Note: Check below for full video. Abstract (cited): "In this paper, we present a self-calibrating framework that jointly optimizes camera parameters, lens distortion, and 3D Gaussian representations, enabling accurate and efficient scene reconstruction. Our technique is particularly effective for high-quality scene reconstruction from large field-of-view (FOV) imagery taken with wide-angle lenses, allowing the scene to be modeled from a smaller number of images. We introduce a novel method for modeling complex lens distortions using a hybrid network that combines invertible residual networks with explicit grids. This design effectively regularizes the optimization process, achieving greater accuracy than conventional camera models. Additionally, we propose a cubemap-based resampling strategy to support large FOV images without sacrificing resolution or introducing distortion artifacts. Our method is compatible with the fast rasterization of Gaussian Splatting, adaptable to a wide variety of camera lens distortions, and demonstrates state-of-the-art performance on both synthetic and real-world datasets."show more

🚨 SCIENTISTS ARE USING AI TO MAP A HIDDEN... “CLEANING SYSTEM” INSIDE THE HUMAN BRAIN AND IT COULD CHANGE HOW WE UNDERSTAND SLEEP, AGING, AND NEURODEGENERATIVE DISEASE. It’s called the glymphatic system a vast network of fluid channels that flushes toxic waste from the brain while you sleep. For years it was almost impossible to observe in detail. Now AI-powered imaging is revealing it like a living galaxy of microscopic rivers and pathways inside neural tissue. Why this matters: Your brain produces toxic proteins constantly. The glymphatic system is one of its primary waste-clearance mechanisms clearing the very proteins linked to Alzheimer’s, Parkinson’s, and other neurodegenerative diseases. But here’s the unsettling part: This cleaning system becomes dramatically less efficient with age, poor sleep, stress, and brain injury. Sleep may not just “rest” your mind it may literally wash your brain. The deeper implication is staggering: The brain isn’t just a computer. It’s a dynamic, living network that constantly rebuilds and cleanses itself in real time. The more we map it, the more it looks like an entire universe of connected energy flows inside our skulls. What if some neurological diseases begin when the brain can no longer properly “wash” itself at night? Follow for more frontier neuroscience and future technology.show more

Do you ever wonder what happens inside the mind... of an elite athlete? I absolutely love this perspective from gold medal freeskier Eileen Gu on the power of our mindset and belief system: "You can control how you think. And therefore, you can control who you are." Athletes don’t just magically create routines and habits. They’re supported by coaches who use the principles of behavioral science to set them up for success. That means using techniques to reduce decision fatigue and lower stress. Through neuroplasticity, the small choices we repeat every day can strengthen our neural circuits and rewire our brains to make certain behaviors more automatic, which is exactly what Gu has trained her mind to do. As Gu said, “With neuroplasticity on my side, I can become exactly who I want to be.” What was your favorite moment of the Winter 2026 Olympics? Let me know in the comments!show more

I believe the "Pit" described in the book of... Revelation is a Galactic Federation prison deep under Antarctica, where "Satan" and "Lucifer" are already confined. From Pleiadian contact we know that the primary leader of the dark forces on Earth is a reptilian with four arms named Pidkozox. He's from the planet Uranus (Nebulac) in our solar system, but in a different dimension. Pidkozox is the father of two Sirian sons, Ashtar and Oppisheklio. Elder Ashtar is the leader of Sirius, a close friend to Elder Ikai, and a respected Galactic Federation commander. Oppisheklio is Earth's greatest deceiver, who played Good Cop to his father's Bad Cop. They were known by many names, including Enlil and Enki, Zeus and Apollo, Baal and Yahweh. They can't harm us directly and rely on human free will to carry out their plans. In blood rituals, they give commands to elites, who then control networks of puppets worldwide. We're in a system with oversight by Galactic Federation which allows dark forces to deceive us without harming us directly, and allows humans to harm each other with free will. Until the Shift, we're dealing with dark plans carried out by humans, as well as spiritual warfare, but we don't have to worry about physical encounters with negative extraterrestrials or defeating the dark forces.show more

Model-Free Reinforcement Learning (MFRL) has been alluring, especially with... supercharged compute with physics on GPU. However, the methods use 0-th order gradients, and are often not the best optimizers. Can we do better than PPO in continuous control for robotics? Turns out yes! 🥳 tl;dr: Faster, better RL than PPO in continuous control 💪 The answer lies in using more information from the simulation. We are juicing the simulation on GPU as it is, why not use it for gradients as well? This has been a driving question in a series of our works. We first studied this problem in ICLR 2022 paper on Short Horizon Actor Critic Naive gradient based methods are stuck in local minima and have exploding/vanishing gradients. SHAC solved this problem truncated rollouts and model based value estimation, where the model is Differentiable Sim. This boosted sample efficiency and wall-clock time immensely especially in high dimensional systems such as humanoids Yet, given enough compute PPO often caught up. Our follow up paper on on Adaptive Horizon Actor Critic at ICML 2024 discovers the cause and provides a fix. However, we find that even when given ground-truth dynamics, not all gradients are useful due to sample error. 1st-Order Model-Based Reinforcement Learning methods employing differentiable simulation provide gradients with reduced variance but are susceptible to bias in scenarios involving stiff dynamics, such as physical contact. We find that back-propagating through contact and long trajectories drastically reduces gradient accuracy. Using this insight, we propose AHAC to dynamically adapt its roll-out horizon to avoid differentiating through stiff contact. AHAC is a first-order model-based RL algorithm that learns high-dimensional tasks in minutes (wall clock) and outperforms PPO by 40%, even in the limit of data provided to PPO. This work is led by Ignat Georgiev alongside Krishnan Srinivasan, Jie Xu, Eric Heiden and ample assistance from warp team at NVIDIA Robotics (Miles Macklin)show more

DISASTER IN THE CHERNIHIV REGION: Due to continuous drone... attacks, the entire power system has been destroyed; the blackout is now worse than in 2022. The situation in the region is critical: due to constant attacks by russian "Shahed" drones, tens of thousands of people are left without electricity, water, and communications. Children do not attend kindergartens and schools, as educational institutions are closed due to lack of electricity. People are sitting in the cold, and critical infrastructure is collapsing. Today, Novhorod-Siverskyi suffered about 20 drone strikes. Drones have been flying over Chernihiv and surrounding settlements for days; power engineers are working in critical conditions, and emergency crews cannot restore power supply due to continuous strikes. Despite four years of continuous drone attacks, the authorities have failed to establish effective protection; interceptor drones or air defense systems do not provide reliable control, and emergency services cannot work effectively. Local authorities and the media have barely covered the disaster. Law enforcement officers and volunteers are forced to patrol the territories and ensure the work of “Points of Invincibility,” while traffic controllers are on duty atshow more
