Dynamic noisy signalling: Online appendix

چکیده
The proof of uniqueness in a larger class of strategies closely follows McLennan et al. (2014) Theorem 1.2, which proves uniqueness in the one-shot Kyle (1985) model. Complex-variable functions are used, so more definitions are needed. A real entire function is smooth and coincides on R with its Taylor series centered at zero. A region is an open connected set D ⊆ C. A function is analytic on D if it is complex-differentiable at every point in D. An entire function is analytic on C. An analytic function is single-valued if it has an unambiguously defined maximal analytic continuation. If a real-valued function coincides on C with its Taylor series centered at zero and is smooth, then it is single-valued.

Continuous time noisy signalling
Most real-life signalling is noisy and in many cases takes time. Information may be revealed gradually (many online customer reviews of a gadget) or by discrete events at random times (scientific breakthrough, oil spill, exposure of a corrupt politician). Both settings lead to behaviour different from noiseless or one-shot signalling situations. Signalling may occur in multiple disjoint interva...

متن کاملA Convolutional Neural Network based on Adaptive Pooling for Classification of Noisy Images
Convolutional neural network is one of the effective methods for classifying images that performs learning using convolutional, pooling and fully-connected layers. All kinds of noise disrupt the operation of this network. Noise images reduce classification accuracy and increase convolutional neural network training time. Noise is an unwanted signal that destroys the original signal. Noise chang...
