Evaluation Metrics
1. The problem is to understand the evaluation metrics used to assess model performance in classification tasks.
2. Accuracy measures overall correctness: $$\text{Accuracy} = \frac
Lagrange Regression
1. **Problem statement:**
We have a noiseless dataset $D = \{(x_1,y_1), \dots, (x_N,y_N)\}$ with distinct $x_i \in \mathbb{R}$. Define the Lagrange basis functions
Misclassified Explanation
1. Masalah yang ditanyakan adalah bagaimana menentukan jumlah data yang salah klasifikasi (misclassified) dan mengapa bisa bernilai 1.
2. Misclassified data adalah data yang predik
