## Make a function: f <- function(x) sum(dnorm(x)) ## compute the gradient: gradient(fun=f, x=1:4) ## Compare with analytical gradient: df <- deriv(~ dnorm(x1) + dnorm(x2), c("x1", "x2"), func=TRUE) dg <- function(x1, x2) as.vector(attributes(df(x1, x2))[[1...
I'd like to compute the gradient of loss with respect to the input vector in TensorFlow.js. Here's what I tried: function f(img) { return tf.metrics.categoricalCrossentropy(model.predict(img), lbl); // (Typo: the order of arguments should be flipped, but it does not affec...
