Sinyal elektrokardiogram (EKG) memiliki informasi yang menggambarkan kondisi kesehatan jantung. Beragai teknik analisis sinyal EKG dikembangkan untuk mengetahui kelainan di jantung secara ototmatis. Pada kenyataannya di Indonesia, kebanyakan perangkat EKG hanya menghasilkan rekaman berupa kertas EKG sehingga metode pengolahan sinyal tidak bisa diterapkan. Pada penelitian ini dilakukan pengenalan kelainan jantung melalui citra rekaman EKG menggunakan analisis tekstur. Garis sinyal EKG yang tergambar dalam citra rekaman EKG diharapkan bisa dibedakan antara kondisi yang satu dengan yang lain. Untuk ekstraksi ciri digunakan ciri statistik orde 1 dan grey level co-occurence matrix (GLCM) pada arah 0o, 45o, 90o, dan 135o. Untuk klasifikasi digunakan K-nearest neighbor (K-NN) dan multilayer perceptron (MLP). Akurasi yang dihasilkan mencapai 44.12% untuk lima kelas data dan 65.82% untuk dua kelas data. Penggunaan teknik pengolahan ctra terbukti mampu meningkatkan akurasi yang semula rendah.Kata kunci: analisis tekstur, K-NN, multilayerperceptron, citra rekaman EKG, pengolahan citra.

Texture feature is a decisive factor in pattern classification problems because texture features are not deduced from the intensity of current pixel but from the grey level intensity variations of current pixel with its neighbors. In this chapter, a new texture model called multivariate binary threshold pattern (MBTP) has been proposed with five discrete levels such as -9, -1, 0, 1, and 9 characterizing the grey level intensity variations of the center pixel with its neighbors in the local neighborhood of each band in a multispectral image. Texture-based classification has been performed with the proposed model using fuzzy k-nearest neighbor (fuzzy k-NN) algorithm on IRS-P6, LISS-IV data, and the results have been evaluated based on confusion matrix, classification accuracy, and Kappa statistics. From the experiments, it is found that the proposed model outperforms other chosen existing texture models.

Abstract Diabetes mellitus is characterized as a chronic disease may cause many complications. The machine learning algorithms are used to diagnosis and predict the diabetes. The learning based algorithms plays a vital role on supporting decision making in disease diagnosis and prediction. In this paper, traditional classification algorithms and neural network based machine learning are investigated for the diabetes dataset. Also, various performance methods with different aspects are evaluated for the K-nearest neighbor, Naive Bayes, extra trees, decision trees, radial basis function, and multilayer perceptron algorithms. It supports the estimation on patients suffering from diabetes in future. The results of this work shows that the multilayer perceptron algorithm gives the highest prediction accuracy with lowest MSE of 0.19. The MLP gives the lowest false positive rate and false negative rate with highest area under curve of 86 %.

AbstractHerein, we implement and access machine learning architectures to ascertain models that differentiate healthy from apoptotic cells using exclusively forward (FSC) and side (SSC) scatter flow cytometry information. To generate training data, colorectal cancer HCT116 cells were subjected to miR-34a treatment and then classified using a conventional Annexin V/propidium iodide (PI)-staining assay. The apoptotic cells were defined as Annexin V-positive cells, which include early and late apoptotic cells, necrotic cells, as well as other dying or dead cells. In addition to fluorescent signal, we collected cell size and granularity information from the FSC and SSC parameters. Both parameters are subdivided into area, height, and width, thus providing a total of six numerical features that informed and trained our models. A collection of logistical regression, random forest, k-nearest neighbor, multilayer perceptron, and support vector machine was trained and tested for classification performance in predicting cell states using only the six aforementioned numerical features. Out of 1046 candidate models, a multilayer perceptron was chosen with 0.91 live precision, 0.93 live recall, 0.92 live f value and 0.97 live area under the ROC curve when applied on standardized data. We discuss and highlight differences in classifier performance and compare the results to the standard practice of forward and side scatter gating, typically performed to select cells based on size and/or complexity. We demonstrate that our model, a ready-to-use module for any flow cytometry-based analysis, can provide automated, reliable, and stain-free classification of healthy and apoptotic cells using exclusively size and granularity information.

Case Based

The CBR (case based reasoning) is a problem solving technique following different strategy compared to the major approaches of the artificial intelligence. It develops remedies to certain problem based on the pre-existing solutions of similar nature. So the problem using the CBR is handled by retrieving and reusing the similar previously solved problems and available solutions respectively. This makes the process functioning alike based on the human activities is instinctively attractive and more beneficial compared to the Conventional_AI as begins to reason out the possible solutions form the shallow base. The CBR due to the exceeding performance are popular among a wide range of applications such as the weather fore casting, medical and engineering diagnosis, aerospace etc. Identification or sorting out or classification take a significant role in cases that is the training examples retrieval as the perfect identification results in perfect case retrieval, this further enables the case based reasoning to arrive to at a perfect remedy for the problem. The retrieval of cases are mostly based on the similarity and utilizes the KNN (K-Nearest Neighbor). The proposed method in the paper integrates the multilayer perceptron with the fuzzy nearest neighbor (MLP-NFF) system with the help of WEKA to deliver a perfect classification to make the CBR-retrieval efficient. The evaluation of the proposed method and its comparison with the KNN is done using the standard data set obtained from the medical field.

Telur adalah salah satu bahan pangan yang mudah dan lazim dijumpai di masyarakat Indonesia. Selain harganya murah, telur merupakan sumber nutrisi penting bagi kesehatan tubuh. Namun telur memiliki kualitas dan kesegaran yang berbeda-beda tergantung pada lingkungan penyimpanan dan kondisi induknya. Kesegaran telur dapat diketahui dari ketebalan dan kekentalan putih telurnya. Semakin tinggi putih telur semakin segar telur tersebut. Tebal atau tinggi albumen dapat diketahui dari nilai HU (Haugh Unit). Dalam makalah ini penulis membahas mengenai cara mendeteksi kualitas dan kesegaran telur menggunakan deteksi objek transparan dengan menggunakan metode GLCM (Grey Level Co-occurrence Method) dan klasifikasi KNN (K-Nearest Neighbor). Telur yang digunakan ialah telur ayam negeri. Pada penelitian ini dilakukan pengujian 51 citra telur, dengan komposisi masing-masing kelas memiliki 17 citra telur AA, 17 citra telur A, dan 17 citra telur B. Sehingga didapatkan akurasi terbaik sebesar 82.35% dengan menggunakan metode GLCM (Grey Level Co-occurrence Matrix) dengan parameter orde dua kontras, energy, korelasi, homogenitas dan arah sudut 45 pada jarak d = 1 dan kuantisasi yang digunakan adalah 8, dengan klasifikasi KNN (K-Neirest Neighbor) menggunakan jarak cosine pada K= 1.
