I’m looking for a training map with something like this: Grayscale Image -> Coloured Image But the dataset can’t be loaded all to the ram as X and Y because of obvious reasons. I looked up the ImageDataGenerator() library, but it didn’t give me a clear answer as to make it work here. Summ…

Error while running CNN for 1 dimensional data in R
I am trying to run 1 dimensional CNN in R using keras package. I am trying to create one-dimensional Convolutional Neural Network (CNN) architecture with the following specification But it is giving me following error Error in py_call_impl(callable, dots$args, dots$keywords) : ValueError: Negative dimension s…
Tensor Flow Conv1D for binary classification CNN
I’m creating a Conv1D layer in a CNN for binary classification, and I’m quite new to Machine Learning and I need some help to figure out the correct values for Conv1D: I would like to know if there is a way to determine the “Right” hyper-parameters that will fit my dataset best. Answer…
Easiest way to see the output of a hidden layer in Tensorflow/Keras?
I am working on a GAN and I’m trying to diagnose how any why mode collapse occurs. I want to be able to look “under the hood” and see what the outputs of various layers in the network look like for the last minibatch. I saw you can do something like model.layers[5].output, but this produces …
Multiclassification task using keras [closed]
Closed. This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 2 years ago. Improve this question Classification (not detection!) of several objects in one image is the pro…
Tensorflow: Error when trying transfer learning: Invalid JPEG data or crop window
I am trying to shape my own custom image dataset into the correct input shape for the pretrained MobileNet model on Tensorflow using their tutorial here. My code: After which I continue with the TF tutorial on transfer learning here. However, I ran into this problem where I suspect the JPEG image is corrupted…
how to perform a backwards correlation/convolution in python
I am trying to perform a backwards correlation (at least that’s what I think it’s called) on 2 matrices to get a resultant matrix. Note: backwards convolution works too, because I’m applying this to a CNN. I have the following two matrices: vals: w0: I essentially want to apply a sliding win…
How downsample work in ResNet in pytorch code?
In this pytorch ResNet code example they define downsample as variable in line 44. and line 58 use it as function. How this downsample work here as CNN point of view and as python Code point of view. code example : pytorch ResNet i searched for if downsample is any pytorch inbuilt function. but it is not. Ans…
Input Shape for 1D CNN (Keras)
I’m building a CNN using Keras, with the following Conv1D as my first layer: I’m training with the function: In which train_df is a pandas dataframe of two columns where, for each row, label is an int (0 or 1) and payload is a ndarray of floats padded with zeros/truncated to a length of 1000. The …
