Detailed Description

The grid cell's model updates probabilities as an average value.

The probability is updated by the following rule:

$p_n=\frac{p_{n-1}+0.5+(p_{new}-0.5)\cdot\alpha}{n}.$

Constructor & Destructor Documentation

AvgTinyCell::AvgTinyCell ( )

inline

Sets the values of the probability $p_0=0$ and $n=0$ .

Definition at line 78 of file tiny_grid_cells.h.

inlineoverridevirtual

Merges a given probability with the stored one as an average value of all given probabilities also using a quality as a weight.

Parameters

[in]	value	- a value of the probability $p_{new}$ .
[in]	quality	- the quality of the experiment value $\alpha$ .

Implements GridCell.
