| claim-type | method— “In this paper, we present a network and training strategy that relies on the strong use of data augmentation to use the available annotated samples more efficiently.” | |
| method — evidence | — “We provide the full Caffe[6]-based implementation and the trained networks4.” | |
| transfer | from artificial intelligence (deep learning / computer vision): convolutional networks applied to biomedical image segmentation— “outperforms the prior best method (a sliding-window convolutional network) on the ISBI challenge for segmentation of neuronal structures in electron microscopic stacks.” | transfers[0] |
| mechanism | overlap-tile prediction with mirrored extrapolation at the border: the missing context outside the image is manufactured by reflecting the image itself, so a tile can be segmented without the network ever seeing beyond the edge— “To predict the pixels in the border region of the image, the missing context is extrapolated by mirroring the input image. This tiling strategy is important to apply the network to large images, since otherwise the resolution would be limited by the GPU memory.” | mechanisms[0] |
| mechanism | elastic deformation of the training images, generated from random displacement vectors on a coarse 3 by 3 grid, sampled from a Gaussian with 10 pixels standard deviation and interpolated to per-pixel displacements with bicubic interpolation the paper's claim that this teaches invariance WITHOUT annotating the transformations is made in the introduction, not in this span; tagged separately or not at all— “We generate smooth deformations using random displacement vectors on a coarse 3 by 3 grid. The displacements are sampled from a Gaussian distribution with 10 pixels standard deviation. Per-pixel displacements are then computed using bicubic interpolation.” | mechanisms[1] |
| mechanism | a per-pixel loss weight, pre-computed from each ground truth segmentation by morphological operations, that both compensates class frequency and forces the network to learn the small separation borders introduced between touching cells the size of that weight - w0 = 10 - is stated in a different sentence and is not claimed here— “We pre-compute the weight map for each ground truth segmentation to compensate the different frequency of pixels from a certain class in the training data set, and to force the network to learn the small separation borders that we introduce between touching cells (See Figure 3c and d). The separation border is computed using morphological… | mechanisms[2] |

When we have changed our mind. Some entries in the table begin with a word in capitals and the reason for it. EVIDENCE CORRECTED — the finding still stands, but we had quoted the wrong sentence from the paper, and the quotation has been replaced with the right one. RETRACTED — the entry itself was wrong; it stays on the page, marked, with the reason, rather than being deleted. WITHDRAWN AND REPLACED — the entry was wrong, and a corrected version of it appears in the entries below. Each mark carries its own reason, in brackets, because the reasons differ from one entry to the next. An entry we have WITHDRAWN is removed from this page and kept in the record, with its reason. A line reading Audit and a date is a later re-reading of the entry against its whole sentence: DOUBTFUL means it was kept, and the reason says what is loose about it. Quotation marks inside the tagger's sentence. Where a tag is the tagger's own sentence, a phrase in quotation marks inside it is borrowed from the paper — the tagger's wording around it is not. The paper's own sentence is the evidence quote for that row; on this page it is withheld with the article, and the article is at its publisher. Nothing inside quotation marks anywhere on this page is ours: if it is quoted, it is the paper's. Whose words a concept carries. A concept entry records a term the paper itself uses, so the term, the sense given for it, and its evidence are the paper's own words, quoted where the paper fixes them. This is the opposite of a sense entry in the tag table, which is the tagger's sentence about how the paper uses a term. Where a concept entry could not be grounded in the paper's words, the entry says so on its own row.
