Question
What is the purpose of the following line of code?1x.view(-1,28*28 )1 pointWe would like to view the first 28 elements of a tensor We need to multiply every element by 28 Images are square and we have to convert them to a vector
Solution
The purpose of the line of code x.view(-1,28*28) is to reshape the tensor x into a 2D tensor with dimensions inferred as -1 and 28*28.
In PyTorch, view() is a function used to reshape tensors. The -1 is a placeholder that tells PyTorch to calculate the correct dimension based on the other specified dimension and the original tensor's total size.
In this case, 28*28 is likely used because the tensor represents an image with a height and width of 28 pixels. By reshaping the tensor to -1,28*28, we are essentially flattening the image into a 1D vector for each image in the batch, which is a common preprocessing step before feeding image data into a fully connected neural network layer.
So, the correct answer is "Images are square and we have to convert them to a vector".
