DL_RIDDLE_QUIZ_1

by Sivaranjini S
1

I am the family of neural networks that operates over hierarchical input defined by a parse tree.

Hints

At every parent node I combine my children using a shared weight matrix.

2

I am the alternative name for a transposed convolution emphasising its mathematical role as the gradient-flow operation of a forward strided convolution.

Hints

I am a misleading term — I am NOT the inverse of convolution and I do NOT recover the original input.

People often use my name even though it is technically incorrect.

3

I am the segmentation loss most directly derived from the F1 score.

Hints

I treat predicted and ground-truth foreground masks symmetrically as sets and penalise their lack of overlap.

I struggle when both masks are empty; people add a small ε to my denominator to avoid division by zero.

4

I am U-Net's mechanism for fusing high-resolution encoder features with upsampled decoder features.

Hints

I do NOT use addition; I append along the channel dimension.

DenseNet is the architecture most associated with applying me densely between every pair of layers in a block.

5

I am a small fully-convolutional network that slides a 3×3 window over a shared backbone feature map.

Hints

I classify each anchor as object/background and regress its bounding-box offset.

I replaced selective search and helped make object detection nearly real-time.
