There is Incremental Learning in the chaotic neural network's learning.
This study examined effects of the binary ratio of 1 and 
in patterns on Incremental Learning.
The ratio of 1 is set to 30%, 40%, 49% and 50% and at each ratio random patterns are generated. Out of 300 patterns, how many patterns Incremental Learning learns are examined.
As a result, the 50% ratio is different from the other ratio on the viewpoint of the number of patterns that can be learned.
Therefore, the binaly ratio of the input patterns have the effect on the learning.
