- survey
    - Deep Learning-based Intelligent Dual Connectivity for Mobility Management in Dense Network **內容提到LSTM預測UE位置**
    - what is RNN?
        - 以範例解釋 Slot Filling
        I would like to arrive <span class="blue">Taipei</span> on <span class="red">November 2nd</span>

        - 會有記憶性，不只考慮當下輸入，左邊的記憶也會影響到輸出
        - 所以兩次相同的輸入，會因會memory不同而有不同輸出

        - 可以是深度，hidden值會一直傳下去
        
    - Long Short-term Memory(LSTM)
        - Input Gate 開啟才能寫入輸入
        - Output Gate 開啟才能讀取輸出
        - Forget Gate 決定memory是否要清空

        - Activation function通常為sigmoid function 0~1
        ![](https://hackmd.io/_uploads/HJMwJHB1T.png)
        - f(Z~f~) 是否要記得之前的值
        - f(Z~i~) 是否要加入新的輸入
        - f(Z~o~) 能否讀取h(C')
