Deep Residual Bidir-LSTM for Human Activity Recognition Using Wearable Sensors

Figure 2

Comparison between a RNN and a LSTM cell. Notations are operators and arrows are information flows. The three operators from left to right are forget gate, input gate, and output gate, respectively. All the three gates have the same operator in form and the same inputs. But they have different weights and biases, which also leads to different values of forgot information , input information , and output information . More details are described in text and (2).
