I have an LSTM model on Python (Keras) in which predicts floats with long decimals. However, the predicted value has fewer decimals than expected. For instance: Input value: 41.39011366661221 Predicted value: 41.396626 Should I use something on my model? I’ve also tried to normalize the input. Unfortuna…

ImportError: dlopen(…): Library not loaded: @rpath/_pywrap_tensorflow_internal.so
I am a beginner at machine learning. I try to use LSTM algorism but when I write from keras.models import Sequential it shows error as below: How can I fix this? Thank you so much! full error message: Answer Problem solved. install tensorflow again with and change the import to
How to hypertune input shape using keras tuner?
I am trying to hypertune the input shape of an LSTM model based on the different values of timesteps. However, I am facing an issue. While initializing the model, the default value of timesteps (which is 2) is chosen, and accordingly, the build_model.scaled_train is created of shape (4096, 2, 64). Thus the va…
Word2Vec + LSTM Good Training and Validation but Poor on Test
currently I’am training my Word2Vec + LSTM for Twitter sentiment analysis. I use the pre-trained GoogleNewsVectorNegative300 word embedding. The reason I used the pre-trained GoogleNewsVectorNegative300 because the performance much worse when I trained my own Word2Vec using own dataset. The problem is w…
What does Tensor[batch_mask, …] do?
I saw this line of code in an implementation of BiLSTM: I assume this is some kind of “masking” operation, but found little information on Google about the meaning of …. Please help:). Original Code: Answer I assume that batch_mask is a boolean tensor. In that case, batch_output[batch_mask] …
name ‘Bidirectional’ is not defined
Im following this tutorial and right when I want to initialize a sequential keras, like the code below: I get an error saying : What is the problem ? it is the exact same code as in the tutorial. Answer You’re most likely missing the import statement from the tensorflow package. It appears that’s there is a l…
Chronologically Propagating Data into a Keras LSTM
I had a question about using LSTMs for processing data over time. That is, how can I feed data one-by-one into an LSTM, without the LSTM forgetting about my previous inputs? I had looked through the Keras “stateful” argument a bit, but it had only made me more confused. I’m not sure whether …
Fitting LSTM model
I am trying to fit LSTM model, but it gave me an error with the shape. my dataset has 218 rows and 16 features including the targeted one. I split the data, %80 for training and %20 for testing, after compiling the model and run it, i got this error: Variable definitions: batch_size = 160 epochs = 20 timestep…
Reshape Python List to Match Input Layer (Data preprocessing – Keras – LSTM – MoCap)
Good Day, I am trying to train LSTM using multiple excel files (Motion Capture Data) as input. Each excel file represents a body motion, I would like to train the network using multiple motions in the training set and in the tests set. Below the example of a single excel file: As for the input shape, it’…
Lstm for multivariate sequence prediction
I am confused with my Stacked LSTM model. Lstm has different type of applications. For example, in the image, two types of LSTM are shown, machine translation and video classification. My model is as follow. Input x has shape (1269, 4, 7). A few samples of input x and output y are as follows. Does this implem…
