LSTM neural network can process long time series data and has long-term memory ability. This paper introduces the algorithm principle of LSTM, and makes time series prediction on the stock market data set
网络博客上面,大多参照这篇文章Time Series Prediction with LSTM Recurrent Neural Networks in Python with Keras.这位博主,有很多时间方面预测的文章,可以去他博客里面学习。这是中文版的Time Series Prediction with LSTM Recurrent Neural Networks in Python with Keras(博客里面有数据集) 在学习上述博客,以及上述...
LSTM is a very great choice to handle with time-series data rather than traditional Recurrent Neural Network (RNN). In RNN, there is a so-called gradient vanishing/exploding problem, and the problem comes from updating the weights by only multiplications. To solve the problem, LSTM considers ...
data_y = [] for i in range(self.len_train - seq_len): x, y = self._next_window(i, seq_len, normalise) data_x.append(x) data_y.append(y) return np.array(data_x), np.array(data_y) 1. 2. 3. 4. 5. 6. 7. 8. ...
# drop rows with NaN values if dropnan: agg.dropna(inplace=True) return agg.values land_temp = pd.DataFrame(data['LandAverageTemperature'].values) ma_vals = data['LandAverageTemperature'].expanding(min_periods=12).mean() ma_vals_inter = ma_vals.interpolate(limit_direction='both') ...
优点。处理a sequence或者a timeseries of data points效果比普通的DNN要好。中间状态理论上维护了从开头到现在的所有信息; 缺点。不能处理long sequence/timeseries问题。原因是梯度消失,网络几乎不可训练。所以也只是理论上可以记忆任意长的序列。 三、LSTM ...
