) Recall that the logistic regression uses the logistic sigmoid function σ(a) =1/(1 + exp(−a)) to model the conditional distribution p(y|x) and then apply maximumlikelihood estimation. One can use the probit function (instead of the logistic function):Φ(a) = INTEGRATION FROM a to - infinity (N(θ|0, 1)dθ)where N(θ|0, 1) is the standard normal distribution. Derive the negative conditional loglikelihood loss for probit regression.Comments: No need to simplify the expression.

) Recall that the logistic regression uses the logistic sigmoid
1/(1 + exp(−a)) to model the conditional distribution p(y|x) and then apply maximum
likelihood estimation. One can use the probit function (instead of the logistic function):
Φ(a) =
where N(θ|0, 1) is the standard
