Hi blakeoft,
Yup. You're right. I just wanna find the gradient of the best fit line. It might not necessary get exactly the same value as what I manual generated from microsoft excel.
As long as it able to generate the gradient of best fit line and R-square value are fine enough.
I have around 10k item wanna to calculate the gradient of best fit line and R-square value of each item.
I unable to manual do it one by one.
Thus hope that got other alternative way able to count it automatic.
Really thanks and appreciate your advice.

NAME
MPSCNNUpsamplingBilinearGradientNode
SYNOPSIS
#import <MPSNNGraphNodes.h>
Inherits MPSNNGradientFilterNode.
Instance Methods
(nonnull instancetype) - initWithSourceGradient:sourceImage:gradientState:scaleFactorX:scaleFactorY:
Class Methods
(nonnull instancetype) + nodeWithSourceGradient:sourceImage:gradientState:scaleFactorX:scaleFactorY:
Properties
double scaleFactorX
double scaleFactorY
Detailed Description
Node representing a MPSCNNUpsamplingBilinear kernel
Method Documentation
- (nonnull instancetype) initWithSourceGradient: (MPSNNImageNode *__nonnull) sourceGradient(MPSNNImageNode *__nonnull)
sourceImage(MPSNNGradientStateNode *__nonnull) gradientState(double) scaleFactorX(double) scaleFactorY
A node to represent the gradient calculation for nearest upsampling training. [forwardFilter gradientFilterWithSources:] is a more
convient way to do this.
Parameters:
sourceGradient The input gradient from the 'downstream' gradient filter.
sourceImage The input image from the forward filter node
gradientState The gradient state from the forward filter
scaleFactorX The X scale factor from the forward pass
scaleFactorY The Y scale factor from the forward pass
Returns:
A MPSCNNUpsamplingBilinearGradientNode
