# Absolute Value Layer |
|
|
|
|
|
* Layer type: `AbsVal` |
|
|
* [Doxygen Documentation](http://caffe.berkeleyvision.org/doxygen/classcaffe_1_1AbsValLayer.html) |
|
|
* Header: [`./include/caffe/layers/absval_layer.hpp`](https://github.com/BVLC/caffe/blob/master/include/caffe/layers/absval_layer.hpp) |
|
|
* CPU implementation: [`./src/caffe/layers/absval_layer.cpp`](https://github.com/BVLC/caffe/blob/master/src/caffe/layers/absval_layer.cpp) |
|
|
* CUDA GPU implementation: [`./src/caffe/layers/absval_layer.cu`](https://github.com/BVLC/caffe/blob/master/src/caffe/layers/absval_layer.cu) |

* Sample |
|
|
|
|
|
layer { |
|
|
name: "layer" |
|
|
bottom: "in" |
|
|
top: "out" |
|
|
type: "AbsVal" |
|
|
} |
|
|
|
|
|
The `AbsVal` layer computes the output as abs(x) for each input element x. |
