Can gradient be negative

WebThe true value of θ is 1, which has a negative log likelihood of 0. But, looking at the expressions above, the gradient is -100. This means gradient descent will keep stepping in the positive direction. And, in this case, the expression for the negative log likelihood will produce increasingly negative values. WebWhen measuring the line: Starting from the left and going across to the right is positive. (but going across to the left is negative). Up is positive, and down is negative. Slope = −4 2 = −2. That line goes down as you move along, so it has a negative Slope.
