1 dzień temu · I found multiple resources online of people writing KMeans from scratch without sklearns and used their code as a template. For a project I am working on, I am trying normalizing the data to a unit sphere and then compute the thetas between the data points and the clusters. Using the euclidean distance formula, I did not run into any issues.
5 godz. temu · Question 7: A (-4, 5) and B(7, 1) are two given points and the point Y divides the line-segment AB externally in the ratio 2:3. Find the coordinates of Y. Question 8: If a point P(k, 4) divides the line segment joining A(2, 9) and B(1, 3) in a ratio m : n then find values of m and n. Read More, Section Formula; Midpoint Formula; Distance Formula

The preimage of a finite point group is called by the same name, with the ...
5 godz. temu · The distance function , called the geodesic distance, is always a pseudometric (a metric that does not separate points), but it may not be a metric. In the finite-dimensional case, the proof that the Riemannian distance function separates points uses the existence of a pre-compact open set around any point.

Given a simple graph with vertices , …,, its Laplacian matrix is defined element-wise as,:= { = , or equivalently by the matrix =, where D is the degree matrix and A is the adjacency matrix of the graph. Since is a simple graph, only contains 1s or 0s and its diagonal elements are all 0s.. Here is a simple example of a labelled, undirected ...
1 dzień temu · The Lennard-Jones potential is a simplified model that yet describes the essential features of interactions between simple atoms and molecules: Two interacting particles repel each other at very close distance, attract each other at moderate distance, and eventually stop interacting at infinite distance, as shown in Figure 1. The Lennard-Jones ...
1 dzień temu · Concentric circles are circles with the same center but different radii. Refer to the graph at the right where A B ‾ \overline{A B} A B is a diameter of the circle. Write an equation of the circle concentric with the circle at the right, with radius 2 units less.
