Hello,

In the Behavior Parameters from the crawler example, there is a Stacked Vector option, which is an history of Sensors from previous instant.

I would like to know what are the initial values sent to the neural network when only the first observation are made? What are the default values?

For example I only have float inputs. Between -1 and 1. The first stack of input are the first values of the observation, and the other are 0? Or simply a duplicate of the first stack vector?

Hello. The stacked vectors are initialized to zeros.
