A data scientist wants to build a Deep Learning model using a single LSTM cell for forecasting a time-seres. The training dataset has several records with 15 time steps each. Each time step consists of three-feature normalized numeric data. If total learnable parameters in this model are 180 , what is the dimensionality of the short state? Answer with all the details. Direct answers or copy and paste from web/any toot/language will not be accepted. [5 Marks]
