mobilenetv2
Syntax
Description
MobileNet-v2 is a convolutional neural network that is 53 layers deep. You can load a pretrained version of the network trained on more than a million images from the ImageNet database [1]. The pretrained network can classify images into 1000 object categories, such as keyboard, mouse, pencil, and many animals. As a result, the network has learned rich feature representations for a wide range of images. The network has an image input size of 224-by-224. For more pretrained networks in MATLAB®, see Pretrained Deep Neural Networks.
You can use classify
to
classify new images using the MobileNet-v2 model. Follow the steps of Classify Image Using GoogLeNet and replace GoogLeNet with
MobileNet-v2.
To retrain the network on a new classification task, follow the steps of Train Deep Learning Network to Classify New Images and load MobileNet-v2 instead of GoogLeNet.

This function requires the Deep Learning Toolbox™ Model for MobileNet-v2 Network support package. If this support package is not installed, then the function provides a download link.
returns a MobileNet-v2 network trained on the ImageNet data set. This syntax is equivalent
to net
= mobilenetv2('Weights','imagenet'
)net = mobilenetv2
.
returns the untrained MobileNet-v2 network architecture. The untrained model does not
require the support package. lgraph
= mobilenetv2('Weights','none'
