    We show that EncDec-AD is robust and can detect anomalies from predictable, unpredictable, periodic, aperiodic, and quasi-periodic time-series. Further, we show that EncDec-AD is able to detect anomalies from short time-series (length as small as 30) as well as long time-series (length as large as 500). PDF Abstract.

    Recurrent Neural Networks, a.k.a. RNN is a famous supervised Deep Learning methodology. Other commonly used Deep Learning neural networks are Convolutional Neural Networks and Artificial Neural Networks.

    As the sequence of frames for each video is long I am using "stateful LSTM" to manage the length of sequences. I have defined my model same as below: def LSTM_Model (): model = Sequential () model.add (LSTM (units = 256, input_shape= (None, 528),\. Step 3: Define traversal¶. After you define the message-passing functions , induce the right order to trigger them. This is a significant departure from models such as GCN, where all nodes are pulling messages from upstream ones simultaneously. In the case of Tree- LSTM , messages start from leaves of the tree, and propagate/processed upwards until they reach the roots.

    Over the past decade, multivariate time series classification has received great attention. We propose transforming the existing univariate time series classification models, the Long Short Term Memory Fully Convolutional Network (LSTM-FCN) and Attention LSTM-FCN (ALSTM-FCN), into a multivariate time series classification model by augmenting the fully convolutional block with a squeeze-and.

    LSTM layer: utilize biLSTM to get high level features from step 2.; Attention layer: produce a weight vector and merge word-level features from each time step into a sentence-level feature vector, by multiplying the weight vector; Output layer: the sentence-level feature vector is finally used for relation classification.
