In this research will show a method for sound-recognition with artificial neural network back propagation concept. The artificial neural network use sigmoid activation function to all layer. Steps to the extraction, first, divide into ten component, second do the Fast Fourier Transform, third continue with Power Spectral Density, fourth count the average.(More)
In this paper we investigate the mixture models for classification tasks in the semi-supervised learning framework in which both labeled and unlabeled data are used for training. This framework is very important since in many domains the labeled data are very expensive while a large number of unlabeled data may be freely available. We present a(More)
Instagram is one of the popular social media applications used by a wide range of people around the world. The significant growth of active Instagram users affects the size of Instagram data. The more number of users, the larger and more various Instagram data is posted. In line with its popularity, in recent years many researchers begin to study and(More)
This paper presents an approach of converting a digital image to a cross stitch pattern. The color space of the input image is quantized and classified into the nearest thread colors using k-NN classifier. Two different metrics are tested, i.e. CIE94 (which using LAB color space) and Euclidean Distance (which using RGB color space). The outputs are(More)
