Each time the random () function is called, it returns an unexpected value within the specified range. The first run is always conducted starting from the initial hyperparameter values of the kernel; subsequent runs are conducted from hyperparameter values that have been chosen randomly from the range of allowed values.

Topic 7: Random Processes
In probability theory and statistics, a Gaussian process is a stochastic process (a collection of random variables indexed by time or space), such that every finite collection of those random variables has a multivariate normal distribution. For example, when investing in the stock market you consider several different stocks and you are interested in how they .5 Application: multivariate Gaussian process regression.random process, and if T is the set of integers then X(t,e) is a discrete-time random process2. The values of xt (ω) define the sample path of the process leading to state ω∈Ω. If only one parameter is passed to the function, it will return a float between zero and the value of the high parameter.
