CP-WOPT: Fill missing data fast in huge multi-dimensional sets
When data has big gaps, many tools just give up.
A method called CP-WOPT finds repeating patterns in multi-dimensional tables and can fill the blanks.
It can work even when 99% missing of the entries are gone, yet still recover the main signal.
The idea is simple: focus only on what you actually measured and ignore the holes.
CP-WOPT was made to scale to large-scale sparse data — imagine a thousand by thousand by thousand table with only a few million known values.
That makes it useful for real problems like noisy brain recordings where electrodes disconnect or in computer networks where collecting every packet is expensive.
Users gets a compact model that reveals hidden structure and helps reconstruct missing pieces.
Try it when your records are messy; it can turn fragments into insight and let you study data you thought were useless.
