## How are recurrent neural networks different from LSTMs?

Recurrent networks, on the other hand, take as their input not just the current input example they see, but also what they have perceived previously in time.

**Can a LSTM solve a long term dependency problem?**

LSTM is a type of RNNs that can solve this long term dependency problem. In our docu m ent classification for news article example, we have this many-to- one relationship. The input are sequences of words, output is one single class or label.

**How are recurrent neural networks used in text classification?**

One of the common ways of doing it is using Recurrent Neural Networks. The following are the concepts of Recurrent Neural Networks: They make use of sequential information. They have a memory that captures what have been calculated so far, i.e. what I spoke last will impact what I will speak next.

### Which is the best rnn for speech analysis?

RNNs are ideal for text and speech analysis. The most commonly used RNNs are LSTMs. The above is the architecture of Recurrent Neural Networks. “A” is one layer of feed-forward neural network.

**Why do we need LSTMs instead of RNN?**

Hence, the RNN doesn’t learn the long-range dependencies across time steps. This makes them not much useful. We need some sort of Long term memory, which is just what LSTMs provide. Long-Short Term Memory networks or LSTMs are a variant of RNN that solve the Long term memory problem of the former.

**When does RMSE increase in a LSTM network?**

The average test RMSE appears lowest when the number of neurons and the number of time steps is set to one. A box and whisker plot is created to compare the distributions. The trend in spread and median performance almost shows a linear increase in test RMSE as the number of neurons and time steps is increased.

## How are timesteps used in LSTM networks for time series?

The trend in spread and median performance almost shows a linear increase in test RMSE as the number of neurons and time steps is increased. The linear trend may suggest that the increase in network capacity is not given sufficient time to fit the data. Perhaps an increase in the number of epochs would be required as well.
