Kaufland data must be under subdirectoy Kaufland
Train and Test folder must be created empty
Preparation of the data
The train/test folders have been created with the sample core given by the mentor mitzev.
The train/test dataset images have been resized to 320×240 grayscale. This give us 76800 pixels.
This web because i couldn’t process al the images on my computer.
The dimensions of the data have been reduced using PCA to 1000 pixels. To show fast results.
I have used a simple neural network to classify the object.
This NN has 1000 inputs, the same number as the PCA output
This NN has 53 outputs, thats the number of clases of the trainf/folder
The value of epochs, learning rate and neurons have been selected using a hyperparameter tuning, not included in the final code.
Evaluation and results
Sorry, the accuracy is poor, a 2.78%.
That’s because this is a simple model, and we have over 53 categories in training dataset. The accuracy is almost random.
