The filter, which costs roughly $15 to make, rests inside a lidded five-gallon plastic bucket with a spigot.
The filter, which had been based on software developed by Mr. Horvitz's researchers, was repaired in the final release of the program.
"The more data, the better," according to Rhett Ryder, CEO of Bath-based The Filter, which powers recommendations for BT Vision, NBC and others.
Bruce Rubin, a spokesman for Epic, said no other hotels owned by the parent company, Kimpton, use the filter, which was manufactured by Culligan International.

The filter, which transforms the input signal into the output is given by (2).
The filter, which is fitted to a digital TV box, blocks out unwanted noise from the 4G signal.
The complexity is mainly based on the high adaptivity of the filter, which requires conditional and decisional processing on the block edge and sample levels, thus, there are many conditional branches in the filter which leads to excessive power consumption.
