In the simplest possible two-layered network, one would have one input neuron, or node, with an activation x, one hidden node, with activation y, and an output node with activation z, where the output is a function of the hidden node activation, which is in turn a function of the input activation.
Worldwide, the average life expectancy at birth was 71.0 years (68.5 years for males and 73.5 years for females) over the period 2010â2013 according to United Nations World Population Prospects 2012 Revision, or 70.7 years (68.2 years for males and 73.2 years for females) for 2009 according to The World Factbook.ethodology [edit]. Life expectancy equals the average number of years a person born in a given country would live if mortality rates at each age were to remain constant in the future.
Women's life expectancy continues to be higher than men's. Although life expectancy has increased over the total US population, women are still expected to live longer than men. The report reveals that in 2012, the life expectancy for females stood at 81.2 years, while the life expectancy for men was 76.4 years. This difference of 4.8 years is the same as reported in 2011.
