Creates bit-level (clipped representation) from a vector
Description
The clipping computes bit-level (clipped representation) from a vector.
Usage
clipping(x)
Arguments
x |
the numeric vector (time series) |
Details
Clipping transforms time series to bit-level representation.
It is defined as follows:
repr_t = {1 if x_t > \mu , 0 otherwise,}
where x_t is a value of a time series
and \mu is average of a time series.
Value
the integer vector of zeros and ones
