Questions tagged [stride]

The stride of an array is the number of locations in memory between beginnings of successive array elements, measured in bytes or in units of the size of the array's elements. Arrays may have a stride larger than their elements' width in bytes, which are called a non-unit stride. One particular use of non-unit stride is for images, when creating subimages without copying the pixel data.

How can I calculate the stride between 2 elements in a 2D array of size 1000 by 1000? C++

I'm trying to find the stride between the index [0][0] and [0][1], as well as between [0][0] and [1][0] to try and understand how it works, so I'm printing out the memory address of each of them and then getting the difference, which is what I…

stride(from: 0.0, to: 10.0, by: 2.0) using Float type instead of Double?

When generating a sequence with stride, how do I pass type hint to Swift to use Float instead of Double? let floats = Array(stride(from: -160.0, to: 0.0, by: 1.0)) // how to use Float instead of Double?

What is the default stride length in Keras' Conv1D?

Currently, I am tuning my model by testing the Kernel size. I have the following code : x = embedding_layer(input_4) x = Conv1D(FILTERS, KERNEL, activation='relu')(x) x = Dropout(DROPOUT)(x) x = Conv1D(FILTERS, KERNEL,…

glVertexAttribPointer and stride parameter requirements

I've been having a weird bug on an OpenGL/GLES application I'm developing. On a certain device (Samsung Galaxy S8), it seems glVertexAttribPointer results in jibberish if the stride parameter is set to 18 bytes. The jibberish disappears if I add two…

How to use conv1d_transpose in TensorFlow for single-channel images?

New to TensorFlow. I have a single-channel image of size W x H. I would like to do a 1D deconvolution on this image with a kernel that only calculates the deconvoluted output row-wise, and 3 by 3 pixels. Meaning that it uses each group of 3 pixels…

as_strided: Linking stepsize (strides of conv2d) with as_strided strides parameter

I found that for generating (X - x + 1, Y - y + 1) patches of size (x,y) from (X,Y) with stride 1, image requires us to give strides parameter as img.strides * 2 or img.strides + img.strides. I don't know how they quickly compute this knowing the…

Why using `MPI_Type_vector` for specifying a stride gap?

In the MPI documentation I read that the difference between MPI_Type_vector and MPI_Type_contiguos is that the first allows to specify a stride gap between the elements of the array. Why one should be interested in doing that instead of using…
