Review for NeurIPS paper: Optimal visual search based on a model of target detectability in natural images

Additional Feedback: The sentence (line 123-124) "We extract features from the last fully connected layer of the CNN (before the classification layer) to use as the input to our classifier" is circular. The caption for figure 2 mentions both "detectability" and "discriminability", but only discriminability is shown. The associated text does not provide a definition of detectability. A definition is only given for discriminability. Is it the case (as seems to be implied by its usage in section 3.1.2) If they are actually different, then a clear definition needs to be given for detectability.
