Are there any 'object detectors' in the hidden layers of CNNs trained to identify objects or scenes?

ICLR 2020 ellagale/testing_object_detectors_in_deepCNNs

We find that the different measures provide different estimates of object selectivity, with precision and CCMAS measures providing misleadingly high estimates.

Learning a Unified Sample Weighting Network for Object Detection

CVPR 2020 caiqi/sample-weighting-network

To this end, we devise a general loss function to cover most region-based object detectors with various sampling strategies, and then based on it we propose a unified sample weighting network to predict a sample's task weights.

MorphoCluster: Efficient Annotation of Plankton images by Clustering

4 May 2020morphocluster/morphocluster

By aggregating similar images into clusters, our novel approach to image annotation increases consistency, multiplies the throughput of an annotator and allows experts to adapt the granularity of their sorting scheme to the structure in the data.

Global-Local Bidirectional Reasoning for Unsupervised Representation Learning of 3D Point Clouds

CVPR 2020 raoyongming/PointGLR

Based on this hypothesis, we propose to learn point cloud representation by bidirectional reasoning between the local structures at different abstraction hierarchies and the global shape without human supervision.
