A search for the standard model Higgs boson produced in association with a top quark pair is presented, using the full pp collision dataset corresponding to an integrated luminosity of 35.9 fb&lt;sup&gt;-1&lt;/sup&gt; collected by the CMS experiment at a center of mass energy of &amp;radic;s = 13 TeV. MVA-based event reconstruction techniques are used to identify final states where the Higgs boson decays to either a W, Z or tau pair by selecting events with two isolated same-sign leptons, and b-jets. The observed best-fit \ th signal strength is 1.7&lt;sup&gt;+0.6&lt;/sup&gt;&lt;sub&gt;-0.5&lt;/sub&gt; times the Standard Model prediction, corresponding to a significance of 3.3 standard deviations above the background-only hypothesis. The observed 95% CL upper limit on the signal strength is 2.9 times the Standard Model prediction, compared to the expected upper limit of 1.0&lt;sup&gt;+0.5&lt;/sup&gt;&lt;sub&gt;-0.3&lt;/sub&gt;
