Multiplying with alpha (a constant to specify the rate of approaching the minimum) in the update rule in...
$begingroup$
Where does the negative sign goes after multiplying with alpha (a constant to specify the rate of approaching the minimum) in the update rule in matrix factorization?
Squared error = (actual rating - predicted rating)^2
Now if I take a partial derivative with respect to two variables, I will get a negative sign. However, in the update rule of these two variable, we multiply with alpha (a constant to specify the rate of approaching the minimum). In different literatures, I have found 'positive' sign appearing in the update rule.Should not it be negative instead?
