résultats obtenus via des variantes de +l'algorithme décrit à la section 2, en utilisant le package présenté à +la section 3. Cet algorithme est systématiquement comparé à deux +approches naïves : * la moyenne des lendemains des jours "similaires" +dans tout le passé, c'est-à-dire prédiction = moyenne de tous les mardis +passé si le jour courant est un lndi par exemple. * la persistence, +reproduisant le jour courant ou allant chercher le lendemain de la +dernière journée "similaire" (même principe que ci-dessus ; argument +"same\_day"). + +Concernant l'algorithme principal à voisins, trois variantes sont +étudiées dans cette partie : * avec simtype="mix" et raccordement +"Neighbors" dans le cas "non local", i.e. on va chercher des voisins +n'importe où du moment qu'ils correspondent au premier élément d'un +couple de deux jours consécutifs sans valeurs manquantes. * avec +simtype="endo" + raccordement "Neighbors" puis simtype="none" + +raccordement "Zero" (sans ajustement) dans le cas "local" : voisins de +même niveau de pollution et même saison. + +Pour chaque période retenue -\/- chauffage, épandage, semaine non +polluée -\/- les erreurs de prédiction sont d'abord affichées, puis +quelques graphes de courbes réalisées/prévues (sur le jour "en moyenne +le plus facile" à gauche, et "en moyenne le plus difficile" à droite). +Ensuite plusieurs types de graphes apportant des précisions sur la +nature et la difficulté du problème viennent compléter ces premières +courbes. Concernant les graphes de filaments, la moitié gauche du graphe +correspond aux jours similaires au jour courant, tandis que la moitié +droite affiche les lendemains : ce sont donc les voisinages tels +qu'utilisés dans l'algorithme. + + \begin{Verbatim}[commandchars=\\\{\}] +{\color{incolor}In [{\color{incolor}1}]:} \PY{n}{library}\PY{p}{(}\PY{n}{talweg}\PY{p}{)} + + \PY{n}{P} \PY{o}{=}
