The calf's weight has been used as an indicator of maternity ability since the past few decades. We propose a method to estimate body weight by modeling the shape of calf using 3D information extracted from the stereo images. This method enables to predict the swelling of the cattle's body by creating a 3D model, which cannot be obtained solely from a 2D image. In addition, it is possible to estimate robust weight regardless of different shooting conditions toward cattle's posture and orientation. An image suitable for estimation is selected from motion images taken by the camera installed in the barn, and 3D coordinates are calculated by the images. Then, only the body is developed with a 3D model as it has the highest correlation with the body weight. Considering that the side of cattle's body may not be exactly perpendicular to the camera's shooting direction, a symmetric axis is extracted to find the inclination of cattle body from the camera in order to generate a 3D model based on the symmetric axis. 3D contiguous cylindrical model is used for the body of a cattle which has a rounded shape. In order to manipulate the shapes of the cylindrical surface, the circle and ellipse fittings are applied and compared. The linear regression equation of the volume of the cylindrical model and the actually measured body weight are used to estimate the cattle weight. As a result of modeling with the proposed method using the actual camera images, the correlation coefficient between the body weight and the model volume was at the best value, 0.9107. Even when experimentally examined with the different 3D coordinates obtained from other types of camera, the MAPE (Mean Absolute Percentage Error) was as low as 6.39%.","PeriodicalId":448008,"journal":{"name":"Proceedings of the 9th International Symposium on Information and Communication Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128816245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of the previous methods have focused on modeling work to accurately estimate the density map and thus infer the count. However, with non-human scenes, which have many clouds, trees, houses, seas etc, these models are often confused, resulting in inaccurate count estimates. To overcome this problem, we propose the \"Weighted Sum of Regressors and Human Classifier\" (WSRHC) method. Our model consists of two main parts: human -- non-human classification and crowd counting estimation. First of all, we built a Human Classifier, which filters out negative sample images (non-human images) before entering into the regressors. Then, the count estimation is based on the regressors. The difference between regressors is the size of the filters. The essence of this method is the count depends on the weighted average of the density map obtained from these regressors. This is to overcome the defects of the previous model, Switching Convolutional Neural Network (Switch-CNN) select the count as the output of one of the regressors. Multi-Column Convolutional Neural Network (MCNN) combines the count and the weight of the Regressors by fixed weights from MCNN, while our approach is adapted for individual images. Our experiments have shown that our method outperform Switch-CNN, MCNN on ShanghaiTech dataset and UCF_CC_50 dataset.","PeriodicalId":448008,"journal":{"name":"Proceedings of the 9th International Symposium on Information and Communication Technology","volume":"50 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126351341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In consequence, Sentiment Analysis (SA) has been becoming a vital part in both academic and commercial standpoint in recent years. However, most of the current sentiment analysis approaches only focus on detecting the overall polarity of the whole sentence or paragraph. That is the reason why this work focuses on another approach to this task, which is Aspect Based Sentiment Analysis (ABSA). The proposed ABSA system in this paper has two main phases: aspect term extraction and aspect sentiment prediction. For the first phase, as to deal with the named-entity recognition (NER) task, it is performed by reusing the NeuroNER [1] program without any modifications because it is currently one of the best NER tool available. For the sentiment prediction task, a bidirectional gated recurrent unit (BiGRU) Recurrent Neural Network (RNN) model which processes 4 features as input: word embeddings, SenticNet [2], Part of Speech and Distance is implemented. However, this network architecture performance on SemEval 2016 [3] dataset showed some drawbacks and limitations that influenced the polarity prediction result. For this reason, this work proposes some adjustments to the mentioned model to solve the current problems and improve the accuracy of the second task.","PeriodicalId":448008,"journal":{"name":"Proceedings of the 9th International Symposium on Information and Communication Technology","volume":"os-44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127782520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within this period, they have much more chance to become pregnant. Successfully detecting this period increase the milk and meat productivity of the whole farm. Recently, a potential approach is unsupervised learning on motion data of the cows, similar to human activity recognition based on motion. In particular, an accelerometer is attached to the neck of the cows to measure their acceleration, then the unsupervised algorithm group the measured acceleration time-series. Recent study adopted bag-of-feature and Discrete Fourier Transform for feature extraction, yet it may not reflect the nature of motion data. Thus, we proposed a method based on Discrete Wavelet Transform to get the multi-resolution feature, Dynamic Time Wraping as clustering distance and Iterative-K-Means as clustering algorithm, to better match with the characteristic of cowsâĂŹ movement. The proposed methods demonstrated higher score on human activity recognition dataset with ground truth and more reliable prediction on cow motion dataset.","PeriodicalId":448008,"journal":{"name":"Proceedings of the 9th International Symposium on Information and Communication Technology","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126760993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are many processing methods, including traditional and modern methods, solving this issue. Traditional methods use edge detection or some other digital image processing for crack detection, but these approaches are sensitive to many types of noise and unwanted objects on the road. For the purpose of increasing accuracy, image pre-processing methods are required for many of these techniques. Recently, some techniques that utilize deep learning to detect cracks in images have achieved high accuracy, without pre-processing. However, some of them are very complicated, some make use of manually collected data and some methods still need some form of pre-processing. In this paper, we propose a method that applies a convolutional neural networks to detect cracks in pavement images. Our research uses two data sets, one public data set and the other collected by ourselves. We also experimentally compare our method with some exiting methods and the experiments show that the proposed approach achieves high accuracy and generates stable models.","PeriodicalId":448008,"journal":{"name":"Proceedings of the 9th International Symposium on Information and Communication Technology","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116387962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fast food restaurants as a type of food service provider have a role in supporting urban lifestyles. Despite the growth of value and transaction volume, there are some fast food categories in Indonesia which have a negative percentage of outlets growth. In general, the location of fast food restaurants divides into two categories. The first one is stand-alone restaurants, and the second is restaurants which located in other public facilities, such as malls, supermarket, and market area. According to the first law of Tobler, closer public facilities will have activity relatedness. This study aims to examine whether proximity between fast food restaurant locations and other public facilities affect categories of fast food restaurants, using spatial decision tree analysis approach. The public facilities examined for proximity to fast food restaurants consist of 11 criteria, which are considered to have a co-location pattern from previous research results. The results will be spatial characteristics of public facilities which expected to be indicators of consumer movement behavior, especially from and to fast food restaurant.","PeriodicalId":448008,"journal":{"name":"Proceedings of the 9th International Symposium on Information and Communication Technology","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130848356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
