 so they can be reused in later calculations. To compute the log-signature over
 any interval $I$, we granularise at a fixed stream resolution $n$ to obtain the
 interval $\tilde I = [k_1/2^n, k_2/2^n)$, and then compute

 The $\mathrm{LogSig}(D_k^n)$ terms on the right-hand-side are either retrieved
 from the cache, or computed from the underlying source. This is essentially the
