    Here's what I love about your lectures: You give the intuition and logic behind the architectures and this helps a lot as opposed to the stone tablet thrown down from the heavens approach. Not only is this important for learning but it also stimulates intuition for the next set of innovations!

      totally true, I just learned about CNN yesterday and prof talked for one hour and a half but I don't understand anything at all, partly because of me being tired, but this MIT lecture make it so easy for me to grasp all these concepts

    This entire series on Deep Learning is a great pleasure to listen to and brainstorm about.
    There are limitless possibilities for AI applications, and I'm highly inspired for some of them.

    This free course on TH-cam is WAY better then a $2k course I took online from Carnegie Mellon University on CV...These MIT lectures are far more in-depth and provide much better examples...

    DL MIT classes are great overall, but there are three small errors in this lecture, please correct if you can:
    - as mentioned in the comments before, fully connected networks do keep spacial relationships, they actually have a much more rigid spatial relationship retention than CNNS
    - CNNs can be seen as a fully connected network with weight sharing and the great advantage is to force the network to give the same feature for the same input anywhere in the image (this makes the network spatially equivariant, or sometimes wrongly referenced as spatially invariant). Of course CNNs require less compute also.
    - Pooling (while it effectively reducing image size) has the main objective of spatially invariance, meaning that we can shift the image and get the same feature at some latent level (up to a point).

    • @jongxina3595
      @jongxina3595 11 หลายเดือนก่อน +6

      theres 2 formulas. Gradient wrt the weight/filter and the gradient wrt to the input. The gradient wrt to the weight is just the outer gradient convolved with the input. The gradient wrt to the input is more complex, its an operation similar to convolution but a bit different. This operation is done between weight and outer gradient.

    Thanks Alex for sharing these lectures online.
    A quick comment about fully connected layer causing loss of spatial information @14:40.
    I don't think fully connected layers result in spatial information loss. All your network has to do is identify that certain indices in the flattened vector correspond to specific locations in the spatial map. We can lose some translation/spatial invariance but not necessary spatial information loss.

  • @vitalispyskinas5595
    @vitalispyskinas5595 ปีที่แล้ว

    The math at 32:13, a double sum, is incorrect.
    Firstly, the filter is indexed with i,j starting at 1, so the input and output matrices are also probably indexed from 1. This means that the first output has p = 1, but since this is added to i, so we start with the row index of x being 2. Basically, we have to add p-1, rather than p, and q-1 rather than q.
    Secondly, The stride is meant to be 2, so we start our filter at double where it would be in the output. So instead of (p-1), we need to add 2(p-1).
    In conclusion, the subscript of x should be i + 2(p-1), j + 2(q-1) ; unless it shouldn't and I made a mistake 💀
    Otherwise, loving the lectures 👍

    Hi, After CNN performed, and pixels are flatten then can we add VAE with GAN to create the same probability distribution of input flattened array and as well some alternative derivativea Or distribution, like cycle gan, road to map.
