we have applied the pca and chisquared methods to the topic of dimensionality reduction. this reduces the data volume considerably, which is my question: can i remove the main component analysis pca and leave the weight by pca method?
i would like to thank you for answering my question.

El que funciona bé ... depèn realment del que estiguis treballant. Alguns vehicles respondran bé a una eina d’exploració genèrica, mentre que d’altres requereixen claus de personalitat específiques per al fabricant. Depèn de què l'utilitzeu i del que intenteu fer amb ell. Si ho busqueu com a alguna cosa per a treballs secundaris, n'aconsegueu una bona: que Modis ja ha pagat per ell mateix i l'actualització l'any que en tinc.

Hola, tengo un router tp-link..; he cambiado la clave y el usuario de acceso al sistema en línea, sin embargo no recordaba la clave y el sistema me sugirió devolver el ROUTER a modo de fábrica presionando el botón de reinicio durante al menos 5 segundos. El problema es que desde el computador no puedo conectarme a la red del router que regresó al nombre que tenía de fábrica. ¿alguien puede ayudarme con la clave por defecto del router?
