In the code, are the cell state and hidden state concatenated?

[zehuanzhang]

In the GeoMAN.py, Line 262 to Line 273:

multiply attention weights with the original input

local_x = local_attn local_inp global_x = global_attn global_inp

Run the BasicLSTM with the newly input

cell_output, state = cell(tf.concat([local_x, global_x], axis=1), state)

Run the attention mechanism.

with tf.variable_scope('local_spatial_attn'): local_attn = local_attention(state) with tf.variable_scope('global_spatial_attn'): global_attn = global_attention(state) attn_weights.append((local_attn, global_attn))

Does this only consider cell state when calculating attention? In the paper Equation (1), cell state and hidden state are concatenated?

The variable "state" actually contains both the cell state and the hidden state.
