Do neural networks accepts other than fixed size of input data?
I think you could try to pad your data to a fixed size(like the maximum length of your descriptors) vector with all 0 or mean value of this vector.
I am implementing a MultiLayer Perceptron , I am extracting the features of images using SIFT algorithm of image processing and I pass those features to the neural network , the features of images that I am considering are descriptors ,every image has different length of descriptors , some image has 200 descriptors and some image has 240 descriptors , means it's varying . But neural networks accepts fixed size of input data .
How can I pass this type of input to it if it accept varied input then how ?
