Can a gradient be negative
WebApr 13, 2024 · Serum ascites albumin gradient (SAAG) is the difference between albumin in the serum and ascitic fluid. A SAAG greater or equal to 1.1 g/dL is characteristic of portal hypertension. A SAAG less than 1.1 g/dL can be seen in hypoalbuminemia, malignancy, or an infectious process. 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.
