The present paper deals with the analysis of Relative Growth Rate and Doubling Time of Neural network research output at international level using time series data from 1969 to 2007. The research output at the international level in 1969 is 2 and it is reached to 123552 in 2007 and the increasing trend is observed year by year. The relative growth rate registers a declining trend at international level. The study period, 1969-2007 records the mean relative growth rate of 0.29 at the world level. The doubling time of neural network research output at the world level starts with 0.63 year in 1971 and it is 6.93 years in 2007.
