Makalah ini menyajikan desain pengklasifikasi dengan pendekatan jaringan neural (syaraf) yang didasarkan pada penggunaan metode Ekapentasi Maksimum (EM). Aturan keputusan pengklasifikasi Bayes menggunakan kesalahan minimum dalam klasifikasi citra gabunganÂ multi waktu. Dalam khasus ini, model jaringan neural perceptron multi lapis Probabilistic Neural Network (PNN), digunakan untuk mengestimasi nonparametrik probabilitas posterior suatu kelas. Korelasi temporal citra dihitung dengan probabilitas gabungan masing-masing kelas secara otomatis dengan menerapkan formula khusus yaitu algoritma ekspektasi maksimum dari citra multi waktu. Eksperimen dilakukan pada dua citra multi waktu yaitu citra Saguling yang diambil pada dua waktu yang berbeda. Berdasarkan hasil eksperimen pada dua daerah uji tersebut, dapat ditunjukkan bahwa tingkat akurasi pengklasifikasi PNN rata-rata lebih baik dibandingkan dengan model Propagasi Balik (BP), dan Ekepektasi Maksimum (EM)Â dapat meningkatkan kemampuan suatu pengklasifikasi. Pengklasifikai PNN dengan menerapkan ekpektasi maksimum memiliki kemampuan pengenalan yang konsisten untuk citra multi waktu, dan juga konsisten untuk setiap pengenalan kategori kelas obyek. Metodologi klasifikasi yang diusulkan dapat memecahkan permasalahan multiÂ waktu secara efektif.KataKunci:Probabilistik Jaringan Syaraf, Ekspektasi Maksimm, Citra Multitemporal, Kelas Objek, PengenalanÂ Â ABSTRACTThis paper presents a classifiers design of neural network approachbased on Expectations Maximum (EM), a Bayes classifier decision rule using the Minimum Error to clasify combined multi-temporal imageries. In this particular, multilayer perceptron neural network model with Probabilistic Neural Network (PNN) is used for nonparametric estimation of posterior class probabilities. Temporal image correlation was calculated Â automatically usingprior joint probabilities of each class by applying a special formula that is algorithm expectation maximum of multi-temporal imagery. Experiments wasperformed on two multi-temporal Saguling imagestakenat two different Â epochs. Based on experimental results on two test areas, it can be shown that the average accuracy rate of PNN classifier is better than the Back Propagation (BP), and the Expectation Maximum (EM) can increase the classifiers ability. Multinomial PNN classifierapplying the maximum expected have a consistent recognition capability for multitemporal imagery, and also consistent for each object class category.

Motif discovery in DNA sequences is one of the most important issues in bioinformatics. Thus, algorithms for dealing with the problem accurately and quickly have always been the goal of research in bioinformatics. Therefore, this study is intended to modify the random projection algorithm to be implemented on R high performance computing (i.e., the R package pbdMPI). Some steps are needed to achieve this objective, ie preprocessing data, splitting data according to number of batches, modifying and implementing random projection in the pbdMPI package, and then aggregating the results. To validate the proposed approach, some experiments have been conducted. Several benchmarking data were used in this study by sensitivity analysis on number of cores and batches. Experimental results show that computational cost can be reduced, which is that the computation cost of 6 cores is faster around 34 times compared with the standalone mode. Thus, the proposed approach can be used for motif discovery effectively and efficiently.

The ability of the teacher to represent a concept using various types of representation is a critical competency. Teachers who have limited multiple representation abilities will not be able to provide a holistic and appropriate learning experience because students have different abilities in constructing their knowledge. This study aims to determine the multiple representation ability of Physics teacher by using instruments to test multiple representations on the topic of Newton’s law consisting of text representations, images, pictorial diagrams, tables, graphs, and mathematical equations. The subjects in this study were 30 high school Physics teachers in North Maluku who were determined based on the purposive sampling technique. Data on multiple teacher representation abilities were analyzed using descriptive statistics. The results of the data analysis showed that the multi-representation ability of high school physics teachers in Newton’s law concept was in the medium category (55.7%) with the highest achievement occurring in the type of mathematical representation and the lowest in the pictorial diagram representation types for both female and male teachers. Besides, based on data implemented using SPSS 2.0, it can be concluded that there are no significant differences with the ability of teacher’s multi-representation based on gender and teacher’s teaching experience.

The study was aimed at determining the effectiveness of learning using TPACK (Technological Pedagogical and Content Knowledge) framework in helping the change of reasoning patterns and modes of Biology prospective teachers so that it facilitates in encompassing the Embryology as one of abstract concepts. The subjects used were 49 students of Biology teachers who were having a contract in Embryology course in Biology Education Study Program, in a private educational institute in Bandung. The research design used was quasi-experimental with time-series design type. The measurement of the level of reasoning ability, patterns, and modes of the students were done through the Test of Logical Thinking (ToLT) three times (before the learning program takes place, after learning the first four main subjects, and after the learning program was over). The results showed that the Embryology learning with TPACK framework could directly change the from concrete and transitional reasoners categories to formal reasoners. The learning with TPACK framework also influenced the shift of the students’ logical thinking modes; from the ownership of proportional and/or correlational mode to the ownership of two or three reasoning modes between proportional, probability, correlational, and combinatorial, except the variable control mode.
