When classifying images into tiger and lions, which image classification algorithm finds the best plane that divides a dataset into two classes?1 pointK-Nearest NeighboursLogistic RegressionSupport Vector MachinesK-Means
Solution
The best algorithm for finding the optimal plane that divides a dataset into two classes, such as classifying images into tigers and lions, is the Support Vector Machines (SVM). SVM is a supervised machine learning algorithm which can be used for both classification or regression challenges. However, it is mostly used in classification problems. In this algorithm, we plot each data item as a point in n-dimensional space (where n is number of features you have) with the value of each feature being the value of a particular coordinate. Then, we perform classification by finding the hyper-plane that differentiates the two classes very well.

You are fine-tuning a support vector machine (SVM) classifier to categorise images based on their content. The dataset consists of various animal images, and you suspect that different kernel functions might yield better classification accuracy. You decide to test which SVM kernel—linear or radial basis function (RBF)—works best for your specific dataset. Below is your initial code setup:from sklearn.svm import SVCfrom sklearn.datasets import load_digitsfrom sklearn.model_selection import train_test_splitfrom sklearn.metrics import accuracy_score# Load a dataset of digit imagesdigits = load_digits()X = digits.datay = digits.target# Split the data into training and testing setsX_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.25, random_state=42)# Initialise two SVM classifiers, one with a linear kernel and another with an RBF kernelsvm_linear = SVC(kernel='linear')svm_rbf = SVC(kernel='rbf')# [Your Code Here] - Train both classifiers on the training data# [Your Code Here] - Predict the test set results with both classifiers# [Your Code Here] - Calculate and print the accuracy scores for both classifiersWhich of the following options correctly completes the task of training both SVM classifiers, predicting the test set results, and calculating the accuracy for eachsvm_linear.train(X_train, y_train)svm_rbf.train(X_train, y_train)y_pred_linear = svm_linear.classify(X_test)y_pred_rbf = svm_rbf.classify(X_test)print("Linear Kernel Accuracy:", accuracy_score(y_test, y_pred_linear))print("RBF Kernel Accuracy:", accuracy_score(y_test, y_pred_rbf))svm_linear.fit(X_train, y_train)svm_rbf.fit(X_train, y_train)y_pred_linear = svm_linear.predict(X_test)y_pred_rbf = svm_rbf.predict(X_test)print("Linear Accuracy:", accuracy_score(y_test, y_pred_linear))print("RBF Accuracy:", accuracy_score(y_test, y_pred_rbf))svm_linear.fit(X_train, y_train)y_pred_linear = svm_linear.predict(X_train)svm_rbf.fit(X_train, y_train)y_pred_rbf = svm_rbf.predict(X_train)print("Accuracy with Linear Kernel:", accuracy_score(y_train, y_pred_linear))print("Accuracy with RBF Kernel:", accuracy_score(y_train, y_pred_rbf))svm_linear.fit(X_train, y_train)y_pred_linear = svm_linear.predict(X_test)svm_rbf.fit(X_train, y_train)y_pred_rbf = svm_rbf.predict(X_test)print("Accuracy with Linear Kernel:", accuracy_score(y_test, y_pred_linear))print("Accuracy with RBF Kernel:", accuracy_score(y_test, y_pred_rbf))
