Should I use LSTM?

LSTM networks are well-suited to classifying, processing and making predictions based on time series data, since there can be lags of unknown duration between important events in a time series. LSTMs were developed to deal with the vanishing gradient problem that can be encountered when training traditional RNNs.

Can we use LSTM for image classification?

Yes, the LSTM model can be applied for image classification. But you have first to extract features from images, then you can apply the LSTM model.

Why do we use LSTM for time series analysis?

The LSTM rectifies a huge issue that recurrent neural networks suffer from: short-memory. Using a series of ‘gates,’ each with its own RNN, the LSTM manages to keep, forget or ignore data points based on a probabilistic model. LSTMs also help solve exploding and vanishing gradient problems.

What is the use of LSTM in RNN?

LSTM is basically considered to avoid the problem of vanishing gradient in RNN. Theoretically, the information in RNN is supposed to follow for arbitrary large sequence but in practice this doesn’t hold up.

What is long short term memory (LSTM) neural network?

This is where the Long Short Term Memory (LSTM) neural network came to the rescue. Like RNN neurons, LSTM neurons kept a context of memory within their pipeline to allow for tackling sequential and temporal problems without the issue of the vanishing gradient affecting their performance.

What is an LSTM in machine learning?

LSTMs are a special type of recurrent neural networks (RNNs). As you already know, RNNs are a broad category of neural networks with feedback loops, and are capable of “remembering” and using information about previous inputs. To understand why LSTMs have dominated the field of RNNs, we need to first briefly look at how neural networks are trained.

Can LSTM neural networks predict a time series?

To demonstrate the use of LSTM neural networks in predicting a time series let us start with the most basic thing we can think of that’s a time series: the trusty sine wave. And let us create the data we will need to model many oscillations of this function for the LSTM network to train over.
