Time series forecasting involves developing a predictive model on data where there is an
ordered relationship between observations. In fact, there are many challenges when forecasting
one or more possible future observations because forecasting models add the complexity of order
or temporal dependence between observations. Traditionally, time series forecasting has been
dominated by linear methods like ARIMA because they are well understood and effective on
many problems. However, this linear relationship excludes more complex joint distributions and
many real-world problems have multiple input variables. In this thesis, we focus on developing
a deep learning model as it has already been proved that they are effective on more complex
time series forecasting problems with multiple input variables. Our proposed model is based on
LSTM autoencoder (Long Short Term Memory), which extract complex nonlinear relationships
and perform well for mutivariates inputs. In addition, the ability of the autoencoder to project
the data in latent space help to deal with the limitation of missing data. We conducted our
experiments on a data set of people with type 1 diabetes in order to predict their blood glucose
level for a period of 5 minutes to an hour. We have obtained a good result, which we will work
on improving in the upcoming works, InchaaAllahCôte titre : MAI/0582 En ligne : https://drive.google.com/file/d/1dgX0lB3xwdmu5pvcqrhPGFAWV7YK3fZF/view?usp=share [...] Format de la ressource électronique : A Deep Learning Model for Predication [texte imprimé] / Ammar Assif Menaouel, Auteur ; Seif Eddine Ayad, Auteur ; Daifi,ahlem, Directeur de thèse . - 2022 . - 1 vol (85 f .) ; 29cm.
