 ## Models in Consideration
 * **Tree-based Model**: Decision Tree
-* **Linear/Polynomial-based**: Linear Regression (optional)
-* **Permutation-based** (especially, neural networks): Multi-Layer Perceptron (MLP)
+* **(Pixels) Permutation-based** (especially, neural networks): Convolutional Neural Network (CNN)
 * **Kernel-based**: K-Nearest-Neighbor (KNN)
