Training on multiple data sets with scikit.mlpregressor

I’m currently training my first neural network on a larger dataset. I have splitted my training data to several .npy binary files, that each contain batches of 20k training samples. I’m loading the data from the npy files, apply some simple pre-processing operations, and then start to train my net…

how to convert generated data into pandas dataframe

dataframe machine-learning pandas python scikit-learn

after creating the data. it is tuple and after converting tuple into pandas dataframe so i got 9 features (columns) but when i try to insert 9 cols it says.

Stylegan2-ada tfrecords – ValueError: axes don’t match array, images will work one run and not work the next

generative-adversarial-network google-colaboratory machine-learning python stylegan

I’m working on training a GAN through Google Colab with a dataset of photos I scraped from Wikiart and converted to 1024×1024, but keep getting this error when creating the tfrecords: I set it to print out what files it would stall on, and began taking those out of the data set; but what it stalls …

How can I convert columns of string in dataset to int?

knn machine-learning python

Some of the data in the dataset are in string format and I should map all of them to the numeric form. I want to convert string data in some columns in the dataset to int int to become usable in the knn method. I wrote this code but It has this error. How can I fix it? thank you

multi-threading, what is wrong with my code

machine-learning opencv python

I was trying to make faster my frames in opencv, it was so slow using it normal, so I decided to ask it here Make faster videocapture opencv the answer was to use multi threading to make it faster, so I code it like this it give me no errors, but compared to my other code that is on the

How to add two separate layers on the top of one layer using pytorch?

deep-learning machine-learning neural-network python pytorch

I want to add two separate layers on the top of one layer (or a pre-trained model) Is that possible for me to do using Pytorch? Answer Yes, when defining your model’s forward function, you can specify how the inputs should be passed through the layers. For example: Where forward is a member of MyNet: Tr…

VGG16 Network for Multiple Inputs Images

deep-learning keras machine-learning python tensorflow

I am trying to use the VGG16 network for multiple input images. Training this model using a simple CNN with 2 inputs gave me an acc. of about 50 %, which is why I wanted to try it using an established model like VGG16. Here is what I have tried out: I get this error while calling the Model function.

tf.train.Checkpoint is restoring or not?

deep-learning keras machine-learning python tensorflow

I am running tensorflow 2.4 on colab. I tried to save the model using tf.train.Checkpoint() since it includes model subclassing, but after restoration I saw It didn’t restored any weights of my model. Here are few snippets: When I later restored it I didn’t get any gru weights: I also tried checkp…

I’m trying to train the model using prelu activation function, but I get the following error I’m using the below-mentioned code, kindly let me know how do I correct it. Answer Your tensor input is wrong. You need to set it up like this way Full working code

How to find the regression line for multiple independent variables?

machine-learning matplotlib numpy pandas python

I’m trying to understand how the Multiple Line Regression works in code for machine learning. The issue I’m having is that I don’t get how to set up my regression line properly or if my coefficients are correct. So I guess I can divide my thoughts into three questions. Is my method of findin…
