In order to load the model from file, use model_path instead of model_content.
mobilenet_decode_predictions() returns a list of data frames with variables class_name, class_description, and score (one data frame per sample in batch input). Google MobileNet Implementation using Keras Framework 2. Fine-tuning a Keras model. In the first half of this blog post I’ll briefly discuss the VGG, ResNet, Inception, and Xception network architectures included in the Keras library. See figures below. 5 simple steps for Deep Learning. The way to handle this in practice is to augment your data (in Keras you can do this with these tools). 25_128.
0 UFF parser failed to parse output node (Assertion Error) 0, tensor RT 3. In other words, a class activation map (CAM) lets us see which regions in the image were relevant to this class. By selecting include_top=False, you get the pre-trained model without its final softmax layer so that you can add your own: ordinate transformations, such as ReLU. For each experiment, the class should have a method prefixed with exp_ that returns either a single ExperimentConfig, or a list of ExperimentConfig objects. Automated Optical Inspection is commonly used in electronics industry and manufacturing industry to detect defects in products or components during production. Assume you have 60 time steps with 100 samples of data (60 x 100 in another word) and you want to use RNN with output of 200. Specify your own configurations in conf. mobilenet keras example
