"the same time then we're going to have a more hands-on example basically applying logistic regression on the Emnes digits data set and then if we have time we'll go quickly over to more examples conce..."

"it's possible to use that optimized graph and the Endo's runtime to actually compute some values some output values even inputs we also have a couple of tools that help debug both pianos code and the ..."

"to use TN well first of all we are working with symbolic expression symbolic variables so that will make up a computation graph so let's see how how to do that so to define the symbolic expression so ..."

"so x and y are purely symbolic variables here we will give them values later but for now that's just that's just empty there's another kind of input variables that is share variables and they they're ..."

"a function that returns that and it actually returns not numbers not a numerical expression for that but it returns a symbolic expression that represents that computation again usually without having ..."

"and we can continue extending the graph from these variables for instance to compute update expressions corresponding to gradient descent something like that like we do here so for instance this is wh..."
