Abstract

Understanding a visual scene is an unsolved and daunting task, since scenes can contain a large number of objects, their properties, and interrelations. Extracting the full scene structure is therefore infeasible, but often unnecessary, since ...In modeling vision, there has been a remarkable progress in recognizing a range of scene components, but the problem of analyzing full scenes, an ultimate goal of visual perception, is still largely open. To deal with complete scenes, recent work focused ...

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In Spiegelman's experiment, Qβ phage genome replicated without selection for function lost functional sequence by fourth serial transfer; population evolved to fifth of original length but replicated 15 times faster.

    “The functional sequence was lost by the fourth serial transfer. The sequence population was evolved to be mere fifth of the length of the original sequence but it was replicated 15 times faster [72].”
  • Functional sequences are usually long and their shorter mutants replicate faster, as demonstrated in Spiegelman's experiment.

    “Functional sequences are usually long and their shorter mutants replicate faster, as demonstrated in Spiegelman’s experiment [72,73]”
  • In Spiegelman's RNA selection experiments, the RNA sequence shortened because shorter sequences could be replicated faster.

    “The outcome of the selection experiments was the shortening of the RNA sequence, as shorter sequences could be replicated faster.”
  • Even with exponential replicators, Darwinian evolution does not necessarily lead to complexification and the spontaneous emergence of new function.

    “But even with exponential replicators, Darwinian evolution does not necessarily lead to complexification and the spontaneous emergence of new function, as the Spiegelman experiments made painfully clear [3].”
  • Shorter RNA sequences are replicated at a higher rate than longer sequences in Spiegelman's system.

    “Since shorter sequences are being replicated at a higher rate than longer sequences, shortened mutants are favored over longer sequences.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
