| claim-type | method— “We trained a convolutional neural network (CNN) to map raw pixels from a single front-facing camera directly to steering commands.” | |
| method — evidence | — “Evaluating our networks is done in two steps, first in simulation, and then in on-road tests.” | |
| transfer | from computer vision (convolutional neural networks): a convolutional network taking raw camera pixels, used in place of the perception-plus-control pipeline of robotics so that steering is learned end to end— “We trained a convolutional neural network (CNN) to map raw pixels from a single front-facing camera directly to steering commands.” | transfers[0] |
| mechanism | the steering command is stored as 1/r rather than r, which removes the singularity at straight-ahead and makes the label continuous through zero across left and right turns— “In order to make our system independent of the car geometry, we represent the steering command as 1/r where r is the turning radius in meters. We use 1/r instead of r to prevent a singularity when driving straight (the turning radius for driving straight is infinity). 1/r smoothly transitions through zero from left turns (negative values) to… | mechanisms[0] |
| mechanism | recovery is taught rather than encountered: the training set is augmented with images of the car already displaced from the lane centre, because human driving alone never shows the network a mistake— “Training with data from only the human driver is not sufficient. The network must learn how to recover from mistakes. Otherwise the car will slowly drift off the road. The training data is therefore augmented with additional images that show the car in different shifts from the center of the lane and rotations from the direction of the… | mechanisms[1] |
| mechanism | off-centre viewpoints are synthesised under an approximation the paper states it knows to be wrong - everything below the horizon treated as flat ground, everything above it as infinitely far - accepted because the resulting distortions do not hurt training— “Precise viewpoint transformation requires 3D scene knowledge which we don’t have. We therefore approximate the transformation by assuming all points below the horizon are on flat ground and all points above the horizon are infinitely far away. This works fine for flat terrain but it introduces distortions for objects that stick above the… | mechanisms[2] |
| mechanism | the label for a synthesised viewpoint is not the driver's command but the command that would return the car to the correct place within a fixed two-second horizon— “The steering label for transformed images is adjusted to one that would steer the vehicle back to the desired location and orientation in two seconds.” | mechanisms[3] |
| mechanism | the training frames are filtered by the driver's activity label and then downsampled, because consecutive frames at full rate are near-duplicates— “To train a CNN to do lane following we only select data where the driver was staying in… | mechanisms[4] |

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.
