How to calculate the expectation of Poisson process $N_t$ when its intensity is also stochastic? Since when intensity $lambda_t$ is non-random, then we have
$$E[dN_t] = lambda_tdt.$$
But how about the stochastic $lambda_t?$ I have no idea to calculate it. You can simply assume $lambda_t$ is a Gaussian process.

You can condition on the value of $lambda_t$. So
$E[dN_t] = E[E[dN_t|lambda_t]] = E[lambda_t dt] = E[lambda_t] dt$

$E[dN_t] = E[E[dN_t|lambda_t]] = E[lambda_t dt] = E[lambda_t] dt$
