Each person has an individual walking habit related to human gait, including speed cadence, etc. Thus, gait of different people can be classified. In this paper, gait data was collected from a sensor system called intelligent carpet. The so-called intelligent carpet consists of optical fibers and is based on Photonic Guided-Path Tomography (PGPT). The raw data was pre-processed and separated into single steps. Artificial Neural Network (ANN) was applied to achieve data classification. The specif
