Some colleagues and I collected some stereo data a long time back and utilized feature matching to perform the built-in MATLAB uncalibrated stereo rectification. While the cameras were near-parallel, this calibration results in the disparity range to span both positive and negative values (due to the uncalibrated rectification). I intend to try to fine tune a neural network with this data, but all of the common architectures assume calibrated rectification where disparity ranges from [0, +D].

I was curious if there is there any good way of "converting" the disparity maps and rectified imagery in the old dataset to positive-only for training these nets or do I need to go back and attempt to

Attention is mostly discussed in the context of sequences, but I was thinking about what it meant in the context of message passing. Clearly when a certain word has "attention" it is relaying long-distance information, but is that synonymous with something like belief propagation?

Say, for example, I have a goal to do a multi-task learning workflow where I have a network that predicts both foreground/background segmentation, specific object segmentation, and bounding box regression.

Suppose that there are only labels for 1-2 of the tasks per image (i.e. one input image has labels for bounding boxes and fg/bg segmentation, but no specific object segmentation; one input image has specific objects and bounding boxes, but no fg/bg). Also, suppose that there isn't a lot of training data to use, so I would like to utilize all of the training data even without full label coverage (especially because the feature extraction portions of the network probably benefit from mutua

I recently got a set of dumbbells and an adjustable bench for my house. I've been doing sets of workouts during/between various other activities (while cooking/during commercials/randomly when I want to). I am currently doing either 5x5s or 3x10s depending on the exercise. My question is: is this actually effective? Is there a better way to do a similar thing while being more effective? I find this to be a lot more preferred than going to the gym as often.
