Há 5 horas · The approach emphasizes meaningful distinctions between classes for the K-Nearest Neighbor (KNN) method. Several distance metrics include Euclidean, City Block, Chebyshev, Minkowski (cubic), Mann-Halanobis, Cosine, Correlation, Spearman, Hamming, and Jaccard. The algorithm is set to consider 10 neighbors for classification.

Há 1 dia · TRAPPIST-1 is a cool red dwarf star [c] with seven known exoplanets. It lies in the constellation Aquarius about 40.66 light-years away from Earth, and has a surface temperature of about 2,566 K (2,290 °C; 4,160 °F ). Its radius is slightly larger than Jupiter and it has a mass of about 9% of the Sun.
