在贵公司提供的课程Deep Learning with Matlab第10.3节中，有设置了双层bilstmLayer层，为什么要这么考虑，相比仅设置单层bilstmLayer层，它好在哪里？还有，其隐藏节点数为256的设置依据是什么?

Hi,
I understand that you're asking why two layers of 'bilstm' are used instead of one and why the number of hidden nodes is specifically set to 256.
The reason for using two layers is likely because a double-layer setup can capture more complex patterns in the data by stacking LSTM layers. The first layer learns basic time-based features, while the second layer builds on that to learn deeper, more complex patterns.
As for the 256 hidden nodes, this number was likely chosen because it offers a good balance between accuracy and computational efficiency. Finding the right number of layers and hidden nodes often requires some trial and error, as there’s no fixed answer for every situation.
