Abstract
Autoencoders (AEs) have been applied in several applications such as anomaly
detectors and object recognition systems. However, although the recent
neural networks have relatively high accuracy but sometimes false detection
may occur. This paper introduces AE as an anomaly detector. The proposed
AE is trained using both normal and anomalous data based on convolutional
neural network with three different color models Hue Saturation Value (HSV),
Red Green Blue (RGB), and our own model (TUV). As a result, the trained
AE reconstruct the normal images without change, whereas the anomalous
image would be reconstructed reversely. The training and testing of the
AE in case of RGB, HSV, and TUV color models were demonstrated and Cifar-10
dataset had been used for the evaluation process. It can be noticed that
HSV color model has been more effective and achievable as an anomaly detector
rather than other color models based on Z- and F-test analyses.
