What is the meaning of "trainable_weights" in Keras?

If I freeze my base_model with trainable=false, I get strange numbers with trainable_weights. Before freezing my model has 162 trainable_weights. After freezin

Jupyter notebook failed to process training data

I'm trying to make a classification on an image with the CNN algorithm. When I tried to run it on jupyter notebook(anaconda) it didn't work, but when I run it o

CNN Prediction output to masked image

Given an output prediction of shape [1,21,388,88] from my Unet. How can I plot it as a masked image? I am using PASCAL dataset. Thanks!

model.predict yeilds more predictions than the number of outputs

I've created a multi-class image classifier using CNN. I am using the keras module specifically and I am using generators to fit and then predict 4 different cl

CNN model accuracy fluctuates

Tensorflow/Keras I have developed a CNN model to classify images as circle, triangle or square. However, my accuracy values have wide fluctuations. Is it someth

CNN accuracy plotting

I used a convolutional neural network (CNN) for training a dataset and I want to plotting accuracy for this. Before, I tried to use matplotlib but I couldn't su

How to extract 'image' and 'label' out of Tensorflow?

I've loaded in my train and validation sets from CIFAR10 like so: train = tfds.load('cifar10', split='train[:90%]', shuffle_files=True) validation = tfds.load('
