GRADIENT BOOSTING TREES UNTUK PEMODELAN DAN PREDIKSI BIAYA KERUGIAN ASURANSI MOBIL
Get PDFGradient Boosting is a machine learning algorithm that combines several simple parameter functions that aim to predict a fairly accurate information from existing data. In contrast to statistical methods in general, this Gradient boosting provides interpretable information, while requiring little data preprocessing and tuning of parameters. Boosting Gradient can be applied to classify or regress data, complex interaction is modeled simply and minimizes loss of information while in predictor management, so this algorithm is good enough to be used for modeling the cost of insurance loss. This paper presents the GB theory and its application to the problem of predicting '' at-fault '' accidents on auto loss costs using data from Canadian insurance companies. The predictive accuracy of the model is compared to the conventional Generalized Linear Model (GLM) approach.Gradient Boosting is a machine learning algorithm that combines several simple parameter functions that aim to predict a fairly accurate information from existing data.

PENGARUH VOUCHER GRAB UNLIMITED TERHADAP LOYALITAS MAHASISWA UBM SERPONG DALAM MENGGUNAKAN APLIKASI GRAB
Get PDFGrab merupakan layanan transportasi online yang sangat populer di Indonesia. Penelitian ini membahas pengaruh voucher diskon Grab Unlimited terhadap loyalitas mahasiswa Universitas Bunda Mulia (UBM) Kampus Serpong dalam menggunakan aplikasi Grab. Penelitian ini bertujuan untuk mengevaluasi apakah insentif voucher yang diberikan Grab dapat berdampak terhadap meningkatnya loyalitas pengguna. Metode pengumpulan data dilakukan melalui survei dengan menggunakan kuesioner kepada 102 mahasiswa UBM Serpong yang telah menggunakan aplikasi Grab dengan menggunakan teknik purposive sampling. Metode yang digunakan meliputi uji validitas, reliabilitas, normalitas, serta uji regresi linear sederhana. Hasil uji validitas menunjukkan bahwa semua indikator valid dengan nilai r hitung lebih besar dari 0,3. Uji reliabilitas menunjukkan nilai Cronbach's Alpha sebesar 0,898, yang menunjukkan data yang reliabel. Uji normalitas menggunakan Q-Q plot dan uji Skewness dan Kurtosis menunjukkan bahwa data berdistribusi normal. Uji heteroskedastisitas dengan scatterplot menunjukkan tidak adanya gejala heteroskedastisitas. Data kemudian dianalisis menggunakan teknik regresi linear sederhana untuk menguji hipotesis yang diajukan. Hasil analisis menunjukkan bahwa terdapat pengaruh yang signifikan antara pemberian voucher Grab Unlimited dan loyalitas pengguna terhadap aplikasi Grab (p < 0,05). Implikasi dari penelitian ini adalah pentingnya strategi pemasaran berbasis voucher untuk meningkatkan loyalitas pengguna dalam aplikasi layanan transportasi online. Dengan begitu, perusahaan dapat memanfaatkan strategi pemberian voucher untuk mempertahankan loyalitas pengguna
Live streaming commerce as communication media at Social Bread
Get PDFLive streaming commerce is the most up-to-date promotional tool connecting sellers and buyers. Social Bread utilizes this phenomenon as an institution that provides services for businesses to optimize product sales through the live-stream commerce method. Social Bread is a medium that bridges the buying and selling process. Much research on similar topics has been conducted, especially from China and the United States. However, little has been done in Indonesia, even though Indonesian businesses and society widely use this feature.
