The concept of functional information is an attempt to rigorously define the information content of biological systems. The concept was originated by a group led by Jack W. Szostak in 2003.
The concept of functional information is an attempt to rigorously define the information content of biological systems. The concept was originated by a group led by Jack W. Szostak in 2003. the functional information relative to a given level of function E_x = \theta is defined as I(E_x \geq \theta) = -log_2 F(E_x \geq \theta) This leads to two conclusions: because all possible configurations can achieve zero or more functionality, that is to say F(E_x \geq 0) = 1 , the minimum possible functional information for a system is -log_2 1 , which is zero. for the highest possible level of a degree of function of a system E_x = \theta_{max} , there will be a well defined I(E_x = \theta_{max}) = -log_2 F(E_x = \theta_{max}) Note that functional information of a system E must always be defined relative to a specific function x , without a choice of which it has no meaning.
