I have 2 columns of data, one being the x values and one being the y values. Now I've been tasked with finding the intercept and gradient using these values but I have absolutely no idea how to get started on t
Find the gradient of the following function. f(x,y)=5y-x^3y^2 Compute the gradient of the given function at the given point: The gradient to z = sqrtx^2 + yx cos (4x- y) at (2,3) is? Compute the gradient of the given function at the given point: i) The gradient to {...

How to Find the Vertical Tangent General Steps to find the vertical tangent in calculus and the gradient of a curve: Find thederivativeof the function. The derivative (dy/dx) will give you the gradient (slope) of the curve. Find a value of x that makes dy/dx infinite; you’re looking...
In this example, the gradient is -½. You could also use the gradient to find the equation of the above line (the equation for a linear function is y = mx + b). The line crosses the y-axis at point B when y = 3. Therefore, the equation would be y = -½ + 3. The Grad...
section of ReLu, it could shut down a neural entirely.However, experimental results tend to contradict that hypothesis, suggesting that hard zeros can actually help supervised training. We hypothesize that the hard non-linearities do not hurt so long as the gradient can propagate along some paths...
[DX,DY] = gradient(-f(x,y)); %line 15 which works only for two variable functions quiver(x,y,DX,DY,0); hold off; If I change the code to: ThemeCopy syms x y; f=input('enter function: ','s'); f = symfun(eval(f), [x y]); g=[-diff(f,x),-diff(f,y)]; f = ...
The gradient descent function — How to find the minimum of a function using an iterative algorithm. The gradient descent in action — It's time to put together the gradient descent with the cost function, in order to churn out the final algorithm for linear regression. Multivariate linear reg...
