Deep Learning Toolbox
Design, train, and analyze deep learning networks
Deep Learning Toolbox™ provides a framework for designing and implementing deep neural networks with algorithms, pretrained models, and apps. You can use convolutional neural networks (ConvNets, CNNs) and long short-term memory (LSTM) networks to perform classification and regression on image, time-series, and text data. You can build network architectures such as generative adversarial networks (GANs) and Siamese networks using automatic differentiation, custom training loops, and shared weights. With the Deep Network Designer app, you can design, analyze, and train networks graphically. The Experiment Manager app helps you manage multiple deep learning experiments, keep track of training parameters, analyze results, and compare code from different experiments. You can visualize layer activations and graphically monitor training progress.
You can exchange models with TensorFlow™ and PyTorch through the ONNX format and import models from TensorFlow-Keras and Caffe. The toolbox supports transfer learning with DarkNet-53, ResNet-50, NASNet, SqueezeNet and many other pretrained models.
You can speed up training on a single- or multiple-GPU workstation (with Parallel Computing Toolbox™), or scale up to clusters and clouds, including NVIDIA® GPU Cloud and Amazon EC2® GPU instances (with MATLAB Parallel Server™).

Design Deep Learning Networks
Create and train a deep network from scratch using the Deep Network Designer app. Import a pretrained model, visualize the network structure, edit layers, tune parameters, and train.
Analyze Deep Learning Networks
Analyze your network architecture to detect and debug errors, warnings, and layer compatibility issues before training. Visualize the network topology and view details such as learnable parameters and activations.

Manage Deep Learning Experiments
Manage multiple deep learning experiments with the Experiment Manager app. Keep track of training parameters, analyze results, and compare code from different experiments. Use visualization tools such as training plots and confusion matrices, sort and filter experiment results, and define custom metrics to evaluate trained models.
Transfer Learning
Access pretrained networks and use them as a starting point to learn a new task. Perform transfer learning to use the learned features in the network for a specific task.
Pretrained Models
Access pretrained networks from the latest research with a single line of code. Import pretrained models including DarkNet-53, ResNet-50, SqueezeNet, NASNet, and Inception-v3.

Network Activations and Visualizations
Extract activations corresponding to a layer, visualize learned features, and train a machine learning classifier using the activations. Use the Grad-CAM, occlusion, and LIME to explain a deep learning network's classification decisions.

ONNX Converter
Import and export ONNX models within MATLAB® for interoperability with other deep learning frameworks. ONNX enables models to be trained in one framework and transferred to another for inference. Use GPU Coder™ to generate optimized NVIDIA® CUDA® code and use MATLAB Coder™ to generate C++ code for the imported model.
