Dalam ilmu komputer dan data science, perbandingan antara algoritma - algoritma memiliki peran penting. Penelitian ini membandingkan performa dua algoritma untuk prediksi atau forecasting, dengan data dari Badan Pusat Statistik mengenai Jumlah Pelanggan Wired dan Wireless Telekomunikasi. Evaluasi dilakukan dengan metrik seperti Mean Absolute Deviation (MAD) untuk regresi linear dan k-nearest neighbors. Hasilnya, MAD regresi linear: 1.520 (wired) dan 46.140 (wireless), serta k - nearest neighbors: 827 (wired) dan 35.723 (wireless). Mean Square Error (MSE) regresi linear: 27.850 (wired) dan 24.907.799 (wireless), k-nearest neighbors: 10.282 (wired) dan 21.165.042 (wireless). Root Mean Square Error (RMSE) regresi linear: 1.668 (wired) dan 49.907 (wireless), k-nearest neighbors: 1.014 (wired) dan 46.005 (wireless). Mean Absolute Percentage Error (MAPE) regresi linear: 15,10% (wired) dan 13,48% (wireless), k-nearest neighbors: 8,57% (wired) dan 9,87% (wireless). Hasil menunjukkan k-nearest neighbors lebih unggul daripada regresi linear dalam prediksi. Algoritma ini, yang utamanya berfungsi sebagai klasifikasi, dapat mengungguli regresi linear dalam tugas prediksi atau forecasting. ----- In computer science and data science, the comparison between algorithms plays a crucial role. This research compares the performance of two algorithms for prediction or forecasting using data from the Central Statistics Agency (Badan Pusat Statistik) regarding the number of Wired and Wireless Telecommunication Customers. Evaluation is conducted using metrics such as Mean Absolute Deviation (MAD) for linear regression and k-nearest neighbors. The results show that for linear regression, MAD is 1,520 (wired) and 46,140 (wireless), while for k-nearest neighbors, it is 827 (wired) and 35,723 (wireless). Mean Square Error (MSE) for linear regression is 27,850 (wired) and 24,907,799 (wireless), and for k-nearest neighbors, it is 10,282 (wired) and 21,165,042 (wireless). Root Mean Square Error (RMSE) for linear regression is 1,668 (wired) and 49,907 (wireless), and for k-nearest neighbors, it is 1,014 (wired) and 46,005 (wireless). Mean Absolute Percentage Error (MAPE) for linear regression is 15.10% (wired) and 13.48% (wireless), while for k-nearest neighbors, it is 8.57% (wired) and 9.87% (wireless). The results indicate that k-nearest neighbors outperform linear regression in prediction. This algorithm, primarily functioning as classification, can surpass linear regression in prediction or forecasting tasks.
