LSTM (Long Short Term Memory) Neural Network: The Solution for Dementia in AI Models
LSTM (Long Short Term Memory) is an innovative Neural Network (NN)* -a class of AI mimicking the human brain- for the study of time series that are long i.e. hundreds or thousands of data points.) Time series are sequential data such as stock prices, population growth, GDP growth, daily weather temperature etc over time in years, months, weeks, days. A primary trait of time series of natural, economic, social phenomena is that the past has an impact on the present and into the future. Thus x is a function of time viz: x=f(t-1, t-2, t-3 etc) where x is the phenomenon and t is time. In Statistics, this is known as autocorrelation. In other words, the phenomenon retains a memory of its past. One of the traits in humans with Dementia is that their short term memory declines rapidly (while long term memory is retained). AI time series models are also afflicted with the machine equivalent of human Dementia. Time series which are very long ...
