.SH "Detailed Description"
.PP 
This depends on Metal\&.framework  This filter is the backward filter for the \fBMPSCNNDropout\fP forward filter\&. It requires the mask data, along with all the associated parameters used to generate the mask, from the forward pass\&. The mask is associated with a \fBMPSCNNDropoutGradientState\fP object\&.
.PP
In this kernel, use the secondaryOffset to apply an offset to the mask data\&. 
.SH "Method Documentation"
.PP 
.SS "\- (nullable instancetype) \fBinitWithCoder:\fP (NSCoder *__nonnull) aDecoder(nonnull id< MTLDevice >) device"
<NSSecureCoding> support 
.PP
Reimplemented from \fBMPSCNNGradientKernel\fP\&.
.SS "\- (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device"
Standard init with default properties per filter type 
.PP
\fBParameters:\fP
.RS 4
\fIdevice\fP The device that the filter will be used on\&. May not be NULL\&. 
.RE
.PP
\fBReturns:\fP
.RS 4
\fBA\fP pointer to the newly initialized object\&. This will fail, returning nil if the device is not supported\&. Devices must be MTLFeatureSet_iOS_GPUFamily2_v1 or later\&.

.SS "\- (nonnull instancetype) \fBinitWithDevice:\fP (nonnull id< MTLDevice >) device(float) keepProbability(NSUInteger) seed(MTLSize) maskStrideInPixels"
Standard init with default properties per filter type\&. 
.PP
\fBParameters:\fP
.RS 4
\fIdevice\fP The device that the filter will be used on\&. 
.br
\fIkeepProbability\fP The probability that each element in the input is kept\&. The valid range is (0\&.0f, 1\&.0f)\&. 
.br
\fIseed\fP The seed used to generate random numbers\&. 
.br
\fImaskStrideInPixels\fP The mask stride in the x, y, and z dimensions, which allows for the broadcasting of mask data\&. The only valid values are 0 and 1 for each dimension\&. For no broadcasting, set the values for each dimension to 1\&. For broadcasting, set desired values to 0\&. 
.RE

\fBReturns:\fP
.RS 4
\fBA\fP valid \fBMPSCNNDropoutGradient\fP object or nil, if failure\&.

.SS "\- maskStrideInPixels\fC [read]\fP, \fC [nonatomic]\fP, \fC [assign]\fP"
The mask stride in the x, y, and x dimensions, which allows for the broadcasting the mask data\&.  The only valid values are 0 and 1 for each dimension\&. For no broadcasting, set the values for each dimension to 1\&. For broadcasting, set desired values to 0\&.
