| Description: | Cricket requires an umpire to signal different events in the game to a distant scorer/bookkeeper. The signals are communicated with motions of the hands. For example, No-Ball is signaled by touching each shoulder with the opposite hand, and TV-Replay, a request for an off-field review of the video of a play, is signaled by miming the outline of a TV screen. The dataset introduced in Ko et al. (2005) consists of four umpires performing twelve signals, each with ten repetitions. The data, recorded at a frequency of 184Hz, was collected by placing accelerometers on the wrists of the umpires. Each accelerometer has three synchronous measures for three axes (X, Y and Z). Thus, we have a six-dimensional problem from the two accelerometers. 60% of the data is used for training and use the rest as testing data. The series are 1197 long.
