Deep Learning Toolbox

Create, analyze, and train deep learning networks

 

Deep Learning Toolbox™ (formerly Neural Network 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 advanced network architectures such as generative adversarial networks (GANs) and Siamese networks using custom training loops, shared weights, and automatic differentiation. Apps and plots help you visualize activations, edit and analyze network architectures, and 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 a library of pretrained models (including NASNet, SqueezeNet, Inception-v3, and ResNet-101).

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 ServerTM).

Get Started:

Networks and Architectures

Use Deep Learning Toolbox to train deep learning networks for classification, regression, and feature learning on image, time-series, and text data.

Convolutional Neural Networks

Learn patterns in images to recognize objects, faces, and scenes. Construct and train convolutional neural networks (CNNs) to perform feature extraction and image recognition.

Long Short-Term Memory Networks

Learn long-term dependencies in sequence data including signal, audio, text, and other time-series data. Construct and train long short-term memory (LSTM) networks to perform classification and regression. 

Working with LSTMs.

Network Architectures

Use various network structures including directed acyclic graph (DAG) and recurrent architectures to build your deep learning network. Build advanced network architectures such as generative adversarial networks (GANs) and Siamese networks using custom training loops, shared weights, and automatic differentiation.

Network Design and Analysis

Create, edit, visualize, and analyze deep learning networks with interactive apps. 

Design Deep Learning Networks

Create a deep network from scratch using the Deep Network Designer app. Import a pretrained model, visualize the network structure, edit the layers, and tune parameters. 

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.

Transfer Learning and Pretrained Models

Import pretrained models into MATLAB for inference. 

Transfer Learning

Access pretrained networks and use them as a starting point to learn a new task and quickly transfer learned features to a new task using fewer training images.

Pretrained Models

Access the latest pretrained networks from research with a single line of code. Import pretrained models including Inception-v3, SqueezeNet, NASNet, and GoogLeNet.

Visualization and Debugging

Visualize training progress, and activations of the learned features in a deep learning network.

Training Progress

View training progress in every iteration with plots of various metrics. Plot validation metrics against training metrics to visually check if the network is overfitting.

Network Activations

Extract activations corresponding to a layer, visualize the learned features, and train a machine learning classifier using the activations. Use the Grad-CAM approach to understand why a deep learning network makes its classification decisions.

Framework Interoperability

Interoperate with deep learning frameworks from MATLAB.

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 CUDA code and use MATLAB Coder™ to generate C/C++ code for the importer model.
