I am trying to classify a series of timestamps using RNN with LSTM. The data consists of timing information extracted from the uplink packets recorded during a website fetch. The dataset contains 100 individual fetch samples of each website in a set of 100 websites, this gives me 10,000 samples.
I would like to teach a neural network to classify sequences of timestamps to which website they belong.
An example sequence would look like:
0.0, 0.25420099, 0.70250899, 0.7434534, 0.8746745, ... 2.54634634
Each of these values represents an offset from the start of the website fetch.
These all differ in lengths and are between ~300 and ~4500 timestamps.
I have tried training the LSTM network in Keras like below:
modelClass = Sequential() modelClass.add(LSTM(100)) modelClass.add(Dense(1, activation='sigmoid')) modelClass.compile(loss='binary_crossentropy', optimizer='adam', metrics=['accuracy']) modelClass.fit(X_tr, y_tr, epochs=3, batch_size=64) print(modelClass.summary()) scores = modelClass.evaluate(X_tst, y_tst, verbose=0) print("Accuracy: %.2f%%" % (scores*100))
Training data is in the shape of
(9000, maximum_sequence_length, 1), however this gave me very bad results. I am new to machine learning and don't fully understand how to find appropriate algorithms for specific tasks. Google searches did not come up with any ways to classify such data.
I would appreciate any suggestions and directions, please let me know if more information is required.
