    1. Precision: It is a measure of correctness achieved in positive prediction i.e. of observations labeled as positive, how many are actually labeled positive. Precision = TP / (TP + FP) Recall: It is a measure of actual observations which are labeled (predicted) correctly i.e. how many observations of positive class are labeled correctly. It is also known as ‘Sensitivity’. Recall = TP / (TP + FN)

      Example: In cancer research you may want higher recall, Since you want all actual positive observations to classified as True Positive. A lower Precision maybe alright because some healthy people classified as cancerous can be rectified later.

    1. I agree with the conclusion that hierarchies and letting users put things in places is good, but I want to posit a more nuanced explanation than "we are set in our ways".

      I think sometimes we don't remember what exactly it is we're looking for. We may not have a word, or a name, or date. But if we put it some place in particular we can find it spatially rather than linguistically.

      This is why I think labels are superior to hierarchies. When we transcend the limitations of physical space would should not throw out space, but we should throw away the constraints of 3D space with its contiguous, volumetric forms. Labels let you put things in as many places as you like. Labels can, too, be hierarchical.

      The problem with the current crop of systems that eschew hierarchy is that they replace it with a text box.

      One could make the argument that smart indexing is just automatic labeling, but I think there's a memory function in having created the labels oneself.

      I'd like to see systems that experiment with more ways to fold space. Shortcuts are like wormholes. Maybe we should have common actions for creating bi-directional ones. On mobile devices I think we should take more advantage of zooming and z-planes.
