For information about the supported compute capabilities, see GPU Computing Requirements (Parallel Computing Toolbox). Use of a GPU requires the Parallel Computing Toolbox™. Using a CUDA-capable NVIDIA™ GPU is highly recommended for running this example. Note: This example requires Deep Learning Toolbox™, Statistics and Machine Learning Toolbox™, and Deep Learning Toolbox™ Model for ResNet-50 Network. The difference here is that instead of using image features such as HOG or SURF, features are extracted using a CNN. For example, the Image Category Classification Using Bag of Features example uses SURF features within a bag of features framework to train a multiclass SVM. 5 videos Deep Learning for Engineers (5 videos) This video series addresses deep learning topics for engineers such as accessing data, training a network, using transfer learning, and incorporating your model into a larger design. ![]() This approach to image category classification follows the standard practice of training an off-the-shelf classifier using features extracted from images. Get Started with Deep Learning Using MATLAB Perform four common deep learning tasks with MATLAB. In this example, images from a Flowers Dataset are classified into categories using a multiclass linear SVM trained with CNN features extracted from the images. 4 videos Introduction to Machine Learning (4 videos) Learn the fundamentals behind machine learning, understand the difference between unsupervised and supervised learning, and watch an example of machine learning workflow. An easy way to leverage the power of CNNs, without investing time and effort into training, is to use a pretrained CNN as a feature extractor. These feature representations often outperform hand-crafted features such as HOG, LBP, or SURF. Implement common deep learning workflows in MATLAB® using real-world image and sequence data. From these large collections, CNNs can learn rich feature representations for a wide range of images. CNNs are trained using large collections of diverse images. A Convolutional Neural Network (CNN) is a powerful machine learning technique from the field of deep learning. ![]()
