Abstract

Kebutuhan user untuk mencari suatu kumpulan atau pangkalan informasi secara otomatis saat ini sudah menjadi hal yang sering dilakukan, untuk memenuhi kebutuhan user menemukan kembali informasi-informasi yang dibutuhkan tersebut maka information retrieval system digunakan. Pencarian dokumen yang dilakukan oleh user pada sebuah database dengan cara menginputkan nama dokumen, maka semua dokumen dengan judul yang hampir mendekati dokumen yang user maksud akan ditampilkan. Hal ini dikarenakan dalam sistem pencarian tersebut, sistem belum dapat mengukur mana dokumen yang paling sesuai yang harus ditampilkan dan yang dimaksud oleh user. Maka dengan masalah seperti ini penulis menggunakan information retrieval. Dalam penelitian ini akan dilakukan perhitungan kemiripan dokumen menggunakan metode Vector Space Model. Dalam metode ini data akan melalui proses token dan indexing sehingga tingkat ketepatan dokumen yang dimaksud oleh user untuk temu kembali informasi akan lebih sesuai.

Abstract

Testing becomes the standard in producing quality software, testing can be assessed through certain measures and methods, one of the benchmarks for software quality is ISO, which was made by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) , In the prediction of software defects software defect prediction error is a very bad thing, the prediction results can have an effect on the software itself. This study compares the results of the Logistic Regression Algorithm and Random Forest before and after the resampling method is applied, the test results show that Random Forest with resampling produces a higher level of accuracy. From the test results above, it can be concluded that the Random Forest with resampling method is more effective in predicting software defects

Abstract

According to the World Health Organization, stress is a type of mental illness that affects human health and there is no one in this world who does not suffer from stress or depression. Stress is a term that is often used synonymously with negative life experiences or life events. . Analysis of data that has an unbalanced class results in inaccuracies in predicting human stress. This study shows that using the Deep Neural Network (DNN) Architecture model by optimizing several parameters, namely the optimizer, Learning rate and epoch. The best DNN Architect results are obtained with 4 Hidden Layers, Adagard Optimization, Learning rate 0.01 and the number of epochs 100. Accuracy, precision, recall and f-measure scores get 98.25%, 83.00%, 98.25%, 91.00%, respectively.
