===ION: Inside Out Network=== | |||
The key idea is that we want a feature vector which uses features from multiple scales. | |||
'''Potential Exam Question''' | |||
We want to use features from multiple levels. The RoI is fixed. | |||
The resolution, number of channels, and magnitude of features can be different. | |||
* Do L2 normalization of the features at different layers | |||
* Concatenate features | |||
* Rescale them. | |||
* Do 1x1 convolution and give it to the FC layer. | |||
