SVM and Neural Network

Question

What is difference between SVM and Neural Network? Is it true that linear svm is same NN, and for non-linear separable problems, NN uses adding hidden layers and SVM uses changi

Answer 1

Running a simple out-of-the-box comparison between support vector machines and neural networks (WITHOUT any parameter-selection) on several popular regression and classification datasets demonstrates the practical differences: an SVM becomes a very slow predictor if many support vectors are being created while a neural network's prediction speed is much higher and model-size much smaller. On the other hand, the training time is much shorter for SVMs. Concerning the accuracy/loss - despite the aforementioned theoretical drawbacks of neural networks - both methods are on par - especially for regression problems, neural networks often outperform support vector machines. Depending on your specific problem, this might help to choose the right model.
