  A direct search for electroweak production of charginos and neutralinos is
presented. Events with three or four leptons, with up to two hadronically
decaying $\tau$ leptons, or two same-sign light leptons are analyzed. The data
sample consists of 137 fb$^{-1}$ of proton-proton collisions with a center of
mass energy of 13 TeV, recorded with the CMS detector at the LHC. The results
are interpreted in terms of several simplified models. These represent a broad
range of production and decay scenarios for charginos and neutralinos. A
parametric neural network is used to target several of the models with large
backgrounds. In addition, results using orthogonal search regions are provided
for all the models, simplifying alternative theoretical interpretations of the
results. Depending on the model hypotheses, charginos and neutralinos with
masses up to values between 300 and 1450 GeV are excluded at 95% confidence
level.
