Abstract

Movie is audio visual communication media, which imply the message the movie creator wants to convey. Movie has several genres namely romantic, horror, thriller, comedy, fantasy and so on. Not a few movie connoisseurs are still confused about the differences in these genres. This resulted in many movie lovers who were difficult to distinguish the genre of movie so that the message in the movie could not be fully conveyed to the audience of the movie. Therefore, the classification of movies based on the synopsis of the movie can be one of the solutions to the problem. Classification in the movie synopsis will help in grouping movies with the appropriate genre. The genre genre classification process based on the synopsis begins with preprocessing, then weighting the term to classification with the Improved K-NN method. Based on the implementation and testing conducted in the movie classification research based on the synopsis using Improved K-NN which uses 250 documents as training data and 50 documents as the test data the best results are precision = 1, recall = 0.88, f-measure = 0.936170213, and an accuracy rate of 88%. As well as comparison with K-NN, it was proven that classification using the Improved K-NN method was better than the K-NN method.

Abstract

Failure in catfish farming is often caused by not finding the best composition combination when you want to start cultivation such as, types of ponds, antiseptic administration, etc. Therefore we need a system that aims to find the best combination of parameters while predicting the condition of the fish before it is implemented in the real world. One method that can be applied to predict fish conditions is certainty factor. However, the performance of certainty factor is highly dependent on experts related to the problem so that the resulting solution is vulnerable to being trapped in the local optimum area. One approach that can be used to overcome this problem is to apply optimization algorithms, namely Particle Swarm Optimization (PSO). PSO explores the search space to find the value of the expert cf based on the value of the particle cost. The value of the cost is designed to minimize the distance between random values ​​and the weight value so that the smaller is close to 0 (zero) the greater the chance of a particle being selected as a solution. This study uses hybrid Particle Swarm Optimization-Certainty Factor to identify the condition of catfish. The quality of Certainty Factor is evaluated using test data from experts by comparing system output. The experimental results show that the PSO-Certainty Factor hybrid algorithm produces better predictive results compared to the Certainty Factor algorithm which is 90%.

Abstract

Choosing food has become a challenge for those who are presented with new food choices. Classification is important for those who have a strict diet regarding food that they consume. Food selection is essential for those who are visually impaired to identify food items. The classification process in this research is initiated with the pre-processing of the image, resulting in a segmented image which is then continued with feature extraction where Hue Saturation Value (HSV) for color extraction and Gray Level Co-Occurence Matrix (GLCM) for texture features. Based on features that have been extracted the next step is to gather relevant features using Information gain to reduce the workload. The last process is classification, using K-Nearest Neighbor. Accuracy results are 95,24% at best using only HSV with k=1 for feature selection. A combination of HSV and GLCM using Information gain results in a accuracy from 57,14% to 87,61%. This also applies to only using GLCM with information gain that raises the accuracy from 57,14% to. 74,28%. With the previous statement taken into consideration, Information Gain as a feature selection method increases accuracy with a significant amount and is able to obtain relevant feature if the list of features is abundant. If there are only a few features used, the accuracy increment is not that significant but it decreases the workload of the system.

Abstract

Food classification is a classic problem that still becomes an interest for many researchers. Several studies have been conducted using only one type of food, which is fruit as the object of the classification. This research was conducted to improve the previous ones. This study uses five types of single food as its object. The method used is color feature extraction using YUV Color Moment, texture feature extraction using Haralick, and feature selection using Information Gain. The classification algorithm is K-Nearest Neighbor (KNN). The highest accuracy obtained is 94.26% obtained from the combined features of the two selected feature extraction methods. From these results, it can be concluded that the application of a combination of feature extraction methods, namely color and texture, and feature selection method greatly influence the food image classification process.

Abstract

To fulfill their basic needs, living things need foods. Foods that have poor quality can cause disease. To avoid this, digital image processing can be used to create a food classification system. Digital image processing is used to analyze features contained in food images. In this study, the feature used to classify the types of food images is a feature of color and texture. Color feature extraction is done by Hue Saturation Value (HSV) color space and texture features using the Local Binary Patterns (LBP) method. Classification is done by the Improved K-Nearest Neighbor (Improved K-NN) method. The test results for the k value indicate that the highest accuracy is obtained at 90.476% with the value of k = 1. When the feature used is only a color feature, the highest accuracy value is obtained at 90.476% with a value of k = 1. When the feature used is only a texture feature, the highest accuracy value is obtained 85.714% with a value of k = 1. The results of testing the classification method showed that the Improved K-NN method produced higher accuracy than the K-NN method with an average accuracy of 80.306%. So the best classification results are obtained by using a combination of color and texture features with the Improved K-NN classification method.
