&lt;p&gt;Pond&#233;ration de la loss pour obtenir un N(z) repr&#233;sentatif de la v&#233;rit&#233;. Pour cela j&apos;ai utilis&#233; les poids calcul&#233;s par Marie et St&#233;phane &#224; partir d&apos;un N(z) th&#233;orique. Je pr&#233;sente dans une premi&#232;re partie les r&#233;sultats de l&apos;ensemble des cross validation  (pas d&apos;ensemble pour ce r&#233;sultat l&#224;) sur la base de test ayant la m&#234;me distribution du N(z) que la base de train. Puis je pr&#233;sente les r&#233;sultats sur Primus (CUBE_CFHTLS_SPECTRO_WIDE1234_unique_balanced_Primuslowz_0001)&lt;/p&gt;

&lt;p&gt;&lt;b&gt;1) R&#233;sultat avec un N(z) repr&#233;sentatif&lt;/b&gt;&lt;/p&gt;

&lt;p&gt;biais = 0.0005984543020493647&lt;br/&gt;
sigma_mad = 0.018951882212039885&lt;br/&gt;
fraction d&apos; outliers =  9.94338630198&lt;br/&gt;

&lt;p&gt;&lt;b&gt;2) R&#233;sultat avec un N(z) non repr&#233;sentatif&lt;/b&gt;&lt;br/&gt;
On constate que &#231;a n&apos;a pas corrig&#233; le biais &#224; bas z...&lt;/p&gt;

&lt;p&gt;biais = 0.04970591677428244&lt;br/&gt;

Inf&#233;rence sur le cube &lt;b&gt;CUBE_WIDE_zspec_Photonly_0001.npz&lt;/b&gt;. Il semblerait que le pr&#233;c&#233;dent cube PRIMUS avait des &#233;toiles car ici les r&#233;sultats sont beaucoup mieux m&#234;me s&apos;il y a encore un l&#233;ger biais &#224; faible redshift.

&lt;p&gt;Voici les performances en terme de m&#233;trique:&lt;br/&gt;
biais = 0.01625062861904333&lt;br/&gt;
