\begin{document}$ H^{\pm} $\end{document} through its bosonic decays, i.e., \begin{document}$ H^{\pm}\rightarrow W^\pm\phi $\end{document} (where ϕ = h or A), within the Type-I two Higgs doublet model (2HDM). The main objective is to demonstrate the available parameter space after applying recent experimental and theoretical exclusion limits. We suggest that \begin{document}$ m_{H^\pm} $\end{document}= 150 GeV is the most probable mass for the \begin{document}$ H^\pm\rightarrow W^\pm\phi $\end{document} decay channel in \begin{document}$ pp $\end{document} collisions at \begin{document}$ \sqrt{s} $\end{document}= 8, 13, and 14 TeV. We also report on the application of a modern machine learning approach to a multivariate technique for heavy charged Higgs production in association with a single top quark through weak interaction to demonstrate its observability in comparison with the most relevant Standard Model backgrounds using the neural networks of boosted decision Tree (BDT), likelihood (LH), and multilayer perceptron (MLP)."> Observability of parameter space for charged Higgs boson in its bosonic decays in two Higgs doublet model Type-1 -
