A Prediction Tournament Paradox
In a prediction tournament, contestants “forecast” by asserting a numerical probability for each of (say) 100 future real-world events. The scoring system is designed so that (regardless of the unknown true probabilities) more accurate forecasters will likely score better. This is true for one-on-one comparisons between contestants. But consider a realistic-size tournament with many contestants...
متن کاملPerceptual switching, eye movements, and the bus paradox.
According to a widely cited finding by Ellis and Stark (1978 Perception 7 575-581), the duration of eye fixations is longer at the instant of perceptual reversal of an ambiguous figure than before or after the reversal. However, long fixations are more likely to include samples of an independent random event than are short fixations. This sampling bias would produce the pattern of results also ...
متن کاملRevising Perceptual Linear Prediction (PLP)
Mel Frequency Cepstral Coefficients (MFCC) and Perceptual Linear Prediction (PLP) are the most popular acoustic features used in speech recognition. Often it depends on the task, which of the two methods leads to a better performance. In this work we develop acoustic features that combine the advantages of MFCC and PLP. Based on the observation that the techniques have many similarities, we rev...
متن کاملVisual prediction and perceptual expertise.
Making accurate predictions about what may happen in the environment requires analogies between perceptual input and associations in memory. These elements of predictions are based on cortical representations, but little is known about how these processes can be enhanced by experience and training. On the other hand, studies on perceptual expertise have revealed that the acquisition of expertis...
متن کاملPerceptual Flicker Visibility Prediction Model
The mere presence of spatiotemporal distortions in digital videos does not have to imply quality degradation since distortion visibility can be strongly reduced by the perceptual phenomenon of visual masking. Flicker is a particularly annoying occurrence, which can arise from a variety of distortion processes. Yet flicker can also be suppressed by masking. We propose a perceptual flicker visibi...
