      Great video. One small thing I wanted to point out: when convolving a filter throughout an image, generally, it's more accurate to center the filter on the pixel you want to apply on rather than using the topleft pixel of the filter. This probably doesn't matter a whole lot in CNNs, but it does if you are looking to use a specific filter like edge detection, corner detection, etc.

      It was for me too, Sam! I use the same Excel example to illustrate zero padding and max pooling as well, which are tools/techniques commonly implemented in CNNs. If you liked this explanation, then you may be interested in those as well!

  • @lixiao2882
    @lixiao2882 5 лет назад +104

    Great video! I learned a lot from watching it. I just want to point out that at around 5:10, the convolution is not a dot product of two matrices. It's simply A[0,0] * B[0,0] + A[0,1] * B[0,1] + A[0,2]* B[0,2] + ...+ A[2,0]*B[2,0] + A[2,1]*B[2,1] + A[2,2]*B[2,2]. First number in the bracket represents row number, and the second represents coloum number. The dot product of two 3x3 matrices should be another 3x3 matrix.

    • @deeplizard
      @deeplizard  5 лет назад +16

      Hey MakersAll - Thank you! Yes, you're right. What we're doing is summing the element-wise products of each pair of elements in the matrices.
      I elaborate more on this in the corresponding blog in the section "a note about the usage of the dot product":
      deeplizard.com/learn/video/YRhxdVk_sIs

    • @elultimopujilense
      @elultimopujilense 4 года назад +30

    • @joshuasloan8434
      @joshuasloan8434 4 года назад +9

      Thank you for this comment! I was worried because I thought my understanding of dot products was incorrect.

    • @leonardosartori9825
      @leonardosartori9825 3 года назад

      In addition to what you mention about the dot product, I would like to point out that what is depicted in the video is not a convolution but actually a correlation. It easier to explain a correlation (because it comes down to a simple element-wise multiplication), but the elements are multiplied differently in a convolution (first element of the image patch is multiplied by the last element of the kernel/filter, second element of the image by second last and so on...)

  • @hena_naaz_khan
    @hena_naaz_khan 2 года назад +3

    @xedasxedas Год назад

    The notion of a feature or feature extractor from classic machine learning, for instance in pixel-wise image classification using random forrest or XGBoost, can help to understand how a bunch of (initial) random weigths (filters) can be learned (more like taught) in order to produce the right output (prediction). People jump right to Deep Learning and forget about what came before (before back propagation as a learning method).
