The future of computing lies beyond traditional data models and processing architectures. Hyperdimensional Computing (HDC) is a potential solution inspired by brain-like information processing—leveraging high-dimensional vectors to encode, manipulate, and reason about data with unparalleled efficiency. Here, we dive deep into the world of neuromorphic computing, vector-based reasoning, and cognitive AI, exploring how HDC is transforming machine learning, robotics, neuroscience, and beyond.
