Chap 15: Convolutional Neural Networks
Chap 27: Segmentation & (Soft)Attention
- Segmentation
- semantic segmentation : 只輸出不同的類別class
- instance segmentation: 即使是同一個class, 不同的個體instance, 也獨立標出
- (Soft)Attention
- Discrete locations
- Continuous locations (Spatical Transformers)
multi-scale, upsampling, downsampling, deconvolution
-
FCN
-
Multi-scale
-
Refinement : iteratively
-
Upsampling
- Deconv = normal conv back-propagation pass, a bad name, sounds like
inverse of conv
, in fact, it meansconv transpose
, orupconvolution
,backward strided conv
1/2 strided convolution
.
