Abstract

Akronim didefinisikan sebagai singkatan yang dibentuk oleh huruf awal atau gabungan beberapa huruf dari istilah penting dalam sebuah frase. Menemukan akronim dan kepanjangannya secara otomatis dalam suatu dokumen teks adalah masalah yang menantang dalam teks mining. Artikel ini membahas tentang penentuan kepanjangan dari akronim berbahasa Indonesia secara otomatis. Ada tiga tahap yang dilakukan. Pertama, kandidat akronim diidentifikasi dalam dokumen teks. Kemudian, kandidat ekspansi dibangun berdasarkan teks yang mengelilingi akronim, dan ketiga, klasifikasi k-NN digunakan untuk memilih ekspansi yang benar dari sebuah akronim. Percobaan dilakukan menggunakan teks yang diperoleh dari empat web berbahasa Indonesia yang berbeda. Hasil menunjukkan bahwa algoritma yang dikembangkan dapat beradaptasi dengan baik pada setiap domain dan memiliki rata-rata akurasi sebesar 89,75%.   Kata Kunci: Penentuan akronim dan ekspansinya, klasifikasi kNN

Abstract

Fractional material still often understood as an abstract matter that there are still many students who have difficulty in understanding the fractional material. One of the problems experienced by students is the difficulty to understand the true concept. In the process learning takes place teacher use a monotonous learning so as to make students feel bored in the learning process that can condition students to be active. Through the model of quantum teaching teachers are expected to be able to make the fractional material easier to students understand and can be applied in everyday life. Through the game, students are expected to have fun without coercion. Therefore, the game can be inserted through the subject matter so that students not only play but they also can make the process of learning. This study aims to determine the efforts of teachers using games in learning mathematics. The subject in this research is six people students the class VA SD IT Al Azhar Banda Aceh. The research data were collected through observation and interviews with students as well as qualitative data is analyzed descriptively. Based on the survey results revealed that teachers have sought to use the game in mathematics, namely teachers organize students playing game, limit the time, guiding students, and observe students during play game. But these efforts have not shown optimal results, due to limited time in the learning and the media used is limited so students have difficulty in completing the answer in the game.

Abstract

Background: In the last decade, the number of registered vehicles has grown exponentially. With more vehicles on the road, traffic jams, accidents, and violations also increase. A license plate plays a key role in solving such problems because it stores a vehicle’s historical information. Therefore, automated license-plate character recognition is needed. Objective: This study proposes a recognition system that uses convolutional neural network (CNN) architectures to recognize characters from a license plate’s images. We called it a modified LeNet-5 architecture. Methods: We used four different CNN architectures to recognize license plate characters: AlexNet, LeNet-5, modified LeNet-5, and ResNet-50 architectures. We evaluated the performance based on their accuracy and computation time. We compared the deep learning methods with the Freeman chain code (FCC) extraction with support vector machine (SVM). We also evaluated the Otsu and the threshold binarization performances when applied in the FCC extraction method. Results: The ResNet-50 and modified LeNet-5 produces the best accuracy during the training at 0.97. The precision and recall scores of the ResNet-50 are both 0.97, while the modified LeNet-5’s values are 0.98 and 0.96, respectively. The modified LeNet-5 shows a slightly higher precision score but a lower recall score. The modified LeNet-5 shows a slightly lower accuracy during the testing than ResNet-50. Meanwhile, the Otsu binarization’s FCC extraction is better than the threshold binarization. Overall, the FCC extraction technique performs less effectively than CNN. The modified LeNet-5 computes the fastest at 7 mins and 57 secs, while ResNet-50 needs 42 mins and 11 secs. Conclusion: We discovered that CNN is better than the FCC extraction method with SVM. Both ResNet-50 and the modified LeNet-5 perform best during the training, with F measure scoring 0.97. However, ResNet-50 outperforms the modified LeNet-5 during the testing, with F-measure at 0.97 and 1.00, respectively. In addition, the FCC extraction using the Otsu binarization is better than the threshold binarization. Otsu binarization reached 0.91, higher than the static threshold binarization at 127. In addition, Otsu binarization produces a dynamic threshold value depending on the images’ light intensity.
