+# The computation process of RNN operator
+
+## 1. Understanding of RNN
+
+**RNN** is a recurrent neural network, including an input layer, a hidden layer and an output layer, which is specialized in processing sequential data.
+
+![RNN](https://user-images.githubusercontent.com/43414102/144739164-d6c4b9ff-d885-4812-8d05-5bf045d3a11b.png)

+
+paddle source code implementation: https://github.com/PaddlePaddle/Paddle/blob/develop/paddle/fluid/operators/rnn_op.h#L812
+
+## 2. How to compute RNN 
+
+ At moment t, the input layer is ![图片](https://paddlejs.bj.bcebos.com/doc/xt.svg), hidden layer is ![图片](https://paddlejs.bj.bcebos.com/doc/st.svg), output layer is  ![图片](https://paddlejs.bj.bcebos.com/doc/ot.svg). As the picture above, ![图片](https://paddlejs.bj.bcebos.com/doc/st.svg)isn't just decided by  ![图片](https://paddlejs.bj.bcebos.com/doc/xt.svg),it is also related to ![图片](https://paddlejs.bj.bcebos.com/doc/st1.svg). The formula is as follows.:
+
+![RNN公式](https://user-images.githubusercontent.com/43414102/144739185-92724c8c-25f7-4559-9b1d-f1d76e65d965.jpeg)
+
+## 3.  RNN operator implementation in pdjs
+
+Because the gradient disappearance problem exists in RNN, and more contextual information cannot be obtained, **LSTM (Long Short Term Memory)** is used in CRNN, which is a special kind of RNN that can preserve long-term dependencies.
+
+Based on the image sequence, the two directions of context are mutually useful and complementary. Since the LSTM is unidirectional, two LSTMs, one forward and one backward, are combined into a **bidirectional LSTM**. In addition, multiple layers of bidirectional LSTMs can be stacked. ch_PP-OCRv2_rec_infer recognition model is using a two-layer bidirectional LSTM structure. The calculation process is shown as follows.
+
+#### Take ch_ppocr_mobile_v2.0_rec_infer model, rnn operator as an example
+```javascript
+{
+	Attr: {
+		mode: 'LSTM'
+		//  Whether bidirectional, if true, it is necessary to traverse both forward and reverse.
+		is_bidirec: true
+		// Number of hidden layers, representing the number of loops.
+		num_layers: 2
+	}
+
+	Input: [
+		transpose_1.tmp_0[25, 1, 288]
+	]
+
+	PreState: [
+		fill_constant_batch_size_like_0.tmp_0[4, 1, 48],  
+		fill_constant_batch_size_like_1.tmp_0[4, 1, 48]
+	]
+
+	WeightList: [
+		lstm_cell_0.w_0[192, 288], lstm_cell_0.w_1[192, 48], 
+		lstm_cell_1.w_0[192, 288], lstm_cell_1.w_1[192, 48],
+		lstm_cell_2.w_0[192, 96], lstm_cell_2.w_1[192, 48], 
+		lstm_cell_3.w_0[192, 96], lstm_cell_3.w_1[192, 48],
+		lstm_cell_0.b_0[192], lstm_cell_0.b_1[192],
+		lstm_cell_1.b_0[192], lstm_cell_1.b_1[192],
+		lstm_cell_2.b_0[192], lstm_cell_2.b_1[192], 
+		lstm_cell_3.b_0[192], lstm_cell_3.b_1[192]
+	]
+
+	Output: [
+	    lstm_0.tmp_0[25, 1, 96]
+    ]
+}
+```

+#### Add op in rnn calculation

+Formula: blas.MatMul(Input,  WeightList_ih, blas_ih) + blas.MatMul(PreState,  WeightList_hh,  blas_hh)

+2) rnn_matmul

+
+3) rnn_cell
+Method: Split the rnn_matmul op output into 4 copies, each copy performs a different activation function calculation, and finally outputs lstm_x_y.tmp_c[1,  1,  48]. x∈[0, 3], y∈[0, 24].
