LSTMs can be applied to a variety of deep learning tasks that mostly include prediction based on previous information. Three noteworthy examples include:

• Text prediction: The long-term memory capabilities of LSTM means it excels at predicting text sequences. In order to predict the next word in a sentence, the network has to retain all the words that preceded it. One of the most common applications of text prediction is in chatbots used by eCommerce sites.
• Stock prediction: Simple Machine Learning (SML) models are able to predict stock values and prices based on inputs such as the opening value and the volume of the stock. While these values do take part in stock prediction, they lack a key component. To properly predict a stock value with high accuracy, the model needs to take into account one of the biggest factors—the trend of the stock. To do so, the model needs to identify the trend based on the values recorded over the preceding days—a task suited to an LSTM network.
• Music composition: LSTM can be applied considering that music is built using long sequences of notes, much like text uses long sequences of words.
