One Day Ahead Prediction of Wind Speed Class
This paper deals with the problem of clustering daily
wind speed time series based on two features referred to as Wr
and H, representing a measure of the relative daily average wind
speed and the Hurst exponent, respectively. Daily values of the
pairs (Wr ; H) are first classified by means of the fuzzy c-means
unsupervised clustering algorithm and then results are used to
train a supervised MLP neural network classifier. It is shown
that associating to a true wind speed time series a time series
of classes, allows performing some useful statistics. Further, the
problem of predicting 1-step ahead the class of daily wind speed is
addressed by introducing NAR sigmoidal neural models into the
classification process. The performance of the prediction model
is finally assessed
One Day
In my piece called “One Day”, I discuss my journey with the uncertainty of a medical diagnosis at age 24. I talk about my past lifestyle, & how it’s dramatically changed recently because of my health. I also hope to encourage people to take better care of themselves & to never take a day for granted.https://digitalcommons.csumb.edu/hcom434_spring2023/1006/thumbnail.jp
