Explore the intricacies of Long Short-Term Memory (LSTM) networks in this 21-minute video tutorial. Discover how LSTMs overcome the limitations of basic recurrent neural networks by effectively handling larger sequences of data without encountering gradient problems. Learn about the sigmoid and tanh activation functions, and delve into the three stages of LSTM: determining the percent to remember, updating long-term memory, and updating short-term memory. Conclude with a practical demonstration of LSTM in action using real data. The video is available with artificial voice dubbing in Spanish and Portuguese for increased accessibility.
