Abstract

Machine learning algorithms are mathematical procedures used to find complex and hidden patterns in data with a high degree of accuracy and have brought major advances in various fields for fast and precise decision making. One of these fields is the field of education, which is to predict the admissions process for postgraduate students. The purpose of admitting postgraduate students is to select prospective students who are qualified and meet the academic requirements set by the institution concerned based on GRE (Graduate Record Examination) scores, TOEFL (Test of English as a Foreign Language) scores, university rankings, letters of recommendation, GPA bachelor degree, and research experience. Success in postgraduate admissions can open opportunities to earn advanced degrees and acquire more in-depth knowledge and skills in areas of interest. In this study, an analysis was carried out on various machine learning algorithm optimizations used to optimize topics or trends in previous studies. In this case, the researcher compares performance and selects the best algorithm optimization to be applied to the topic of graduate student admissions. The results of this review show that the hybrid algorithm has the best performance in optimizing predictions for most of the data in previous studies. The results of this study indicate that the CNN-LSTM (Convolutional Neural Network - Long Short-Term Memory) hybrid model is expected to be an appropriate alternative in optimizing predictions of postgraduate student admissions. Therefore, further research is needed to develop this algorithm and expand its application to the topic of graduate student admissions.

Abstract

Next-word prediction is one of the most frequently used tasks in natural language processing. The Recurrent Neural Network (RNN) method is one method that has been proven to be effective in predicting the next word in a sentence, as it is capable of processing text data with order and context. In this research, various algorithms used in the development of next word prediction using the RNN method were analyzed. Some of these algorithms include LSTM (Long Short-Term Memory) and bidirectional LSTM. The results of this research show that the use of the RNN method in predicting the next word is able to provide better results compared to other methods. However, there are still some challenges that need to be overcome in developing the RNN model to predict the next word. Therefore, further research needs to be done in overcoming these challenges so that the use of the RNN method can be further optimized in predicting the next word in a sentence.

Abstract

Bandwidth allocation optimization is crucial to ensure optimal network performance and user satisfaction. This research aims to identify the best machine learning algorithm between backpropagation and recurrent neural network (RNN) in predicting network load, using two different datasets. The main issue addressed is how to choose the right algorithm for network load prediction to optimize bandwidth allocation. The CRISP-DM methodology was used as the research framework, with four evaluation metrics: Mean Absolute Error (MAE), Mean Squared Error (MSE), Root Mean Squared Error (RMSE), and Mean Absolute Percentage Error (MAPE). The results showed that the backpropagation algorithm provided the best performance on the data with the lowest evaluation matrix: MAE 0.0203, MSE 0.0007, RMSE 0.0281, and MAPE 20%. In conclusion, the backpropagation algorithm is more suitable for predicting bandwidth requirements compared to RNN based on the evaluation metrics used, making it reliable for bandwidth allocation optimization.

Abstract

Setiap manusia dilahirkan dengan perbedaan fisik, psikologis, genetik, dan eksternal yang signifikan yang mungkin mempengaruhi karakter individu. Perbedaan karakter ini terkadang diabaikan oleh individu, terutama selama proses pembelajaran, karena kemampuan siswa dalam menyerap pengetahuan pasti berbeda-beda. Akibatnya, diperlukan sistem untuk mengidentifikasi jenis gaya belajar siswa dan membantu guru dalam menghasilkan kualitas pengajaran yang mudah diterima oleh siswa. Penelitian ini menciptakan sistem e-assessment gaya belajar yang menggunakan algoritma penalaran berdasarkan aturan untuk menentukan gaya belajar siswa seperti visual, auditori, kinestetik, dan campuran. Teknik evaluasi melibatkan perhitungan setiap jawaban tergantung pada kategori gaya belajar, yang menghasilkan persentase untuk menunjukkan jenis pembelajaran yang berlaku. Sistem ini dibangun menggunakan model penelitian ADDIE, dengan VueJS di frontend dan PHP Laravel di backend. Pengujian dilakukan dengan menggunakan metode blackbox dan User Acceptance Testing (UAT). Hasil pengujian blackbox dengan alat Selenium IDE menunjukkan bahwa sistem bekerja sesuai dengan skenario yang ditentukan, dan UAT dengan 30 siswa memperoleh skor 86%, yang menunjukkan bahwa sistem ini dapat digunakan. Metode ini dirancang untuk membantu pengembangan cara belajar yang lebih tepat bagi siswa dan guru.
