# What is the input to the left most LSTM cell c(t-1) and h(t-1)?

Given an LSTM model with 3 cells shown below, what would be the input to the left most cell c(t-1) and h(t-1)?

Your question is related to the initial states of LSTM, where c(t-1) is the cell state (memory) and h(t-1) is the previous LSTM block output.
