Compression is the act of pressing or squeezing something into a smaller space. In computers, compression means making a file smaller so it takes up less storage or travels faster over the internet (a compressed photo or video). It's also used in physics and engineering for a force that squeezes something.
壓縮（把體積變小，也用於電腦檔案壓縮）

- Due to the presence of long-range correlations in language [21], [22] it is not possible to compute accurate measures of the entropy by estimating block probabilities directly. More efficient nonparametric methods that work even in the presence of long-range correlations are based on the property that the entropy of a sequence is a lower bound to any lossless compressed version of it [15]. Thus, in principle, it is possible to estimate the entropy of a sequence by finding its length after being compressed by an optimal algorithm. In our analysis, we used an efficient entropy estimator derived from the Lempel-Ziv compression algorithm that converges to the entropy [19], [23], [24], and shows a robust performance when applied to correlated sequences [25] (see Materials and Methods).
