Wàññi dimension
Wàññi dimension bi dafay wàññi done yi ci kolon yu bari (man-man yi) wàcci ci yenn, boole ci tëye structure bu am solo bi.
Résumé
It fights the 'curse of dimensionality,' speeds up models, and lets you actually visualize complex data in 2D or 3D.

What is Dimensionality Reduction?
Wàññi dimension bi dafay wàññi done yi ci kolon yu bari (man-man yi) wàcci ci yenn, boole ci tëye structure bu am solo bi. Dafay xeex 'malku dimensionnalité', gaawal model yi, ba noppi may la nga xool done yu jafee xam ci 2D wala 3D.
Luy 'mal bu dimensionnalité'?
Ci espace yu am dimension yu kawe lool, point yi dañuy tasaaroo fu sori seen biir, nattukaayi distance yi dañuy yàqu, moo tax model yi dañuy am jafe-jafe gis motif yi, ba noppi dañuy gëna méngoo.

PCA dafay gis cër yi gëna am solo, axes yi gëna am variance, ba noppi tëye yi gëna kawe ndax ñooy gëna yor xibaar yi.
Lu tax ñuy woowe PCA anam 'ligneer'?
Bépp lëf bu mag dafay boole màndarga yi njëkk, kon PCA mënul jàpp jëmmal bu xawa sëgg, bu amul rëdd ci anam wi t-SNE wala UMAP mëna defee.
