3 BACKGROUND ON HDC
Hyperdimensional Computing (HDC) is an emerging paradigm for information processing from the cognitive-neuroscience literature [24]. In HDC, all computation is performed on low-precision and distributed representations of data that accord naturally with highly parallel and low-energy hardware.
The encoding function 𝜙 : X → H embeds data from its ambient representation into HD-space. In general, encoding should preserve some meaningful notion of similarity between input points in the sense that 𝜙 (𝑥) · 𝜙 (𝑥 ′ ) ≈ 𝑘 (𝑥, 𝑥′ ), where 𝑘 is some similarity function of interest on X. In this paper, we use spatiotemporal encoding for time series sensor data, and HDnn for more complex data, such as images, which we explain in the following.
