  • vector spaces - Cosine similarity vs angular distance - Mathematics . . .
    While checking Google's Universal sentence encoder paper, I found that they mention that using a similarity based on angular distance performs better than raw cosine similarity More specifically, they used the following formula for the similarity:
  • How to find angular distance between points? [duplicate]
    The goal is to find angular distance between any two points My only thought so far is to draw a line between a central point and all the lines from the central point to all the others and see where these lines intersect the circle
  • Measuring Objects in the Sky: Angular Size Distance
    The distance between those two lines is known as the angular distance The distance between the two points is called the angular distance Such a distance is expressed in degrees
  • Distance between two points in spherical coordinates
    This form makes it fairly transparent how azimuthal symmetry allows you to automatically eliminate some of the angular dependencies in certain integration problems Another advantage of this form is that you now have at least two variables, namely $\phi$ and $\phi'$ , that appear in the equation only once, which can make finding series
  • Reference to angular distance metric properties.
    The cosine distance is not even a distance for vectors of uni length because it violates the triangle inequality Also, the question was not about the cosine distance but about the angular distance d_a(x,y) = \\theta(x,y) which would also violate the identity of indiscernibles, but the triangle inequality should hold –
  • How to Calculate the Angular Displacement from an Arclength and Radius
    The angular displacement of Earth is {eq}0 5 radians { eq} Example Problem 2 - Rotating Disk Through what angular displacement must a disk of radius 30 cm rotate so that a point on the outer edge
  • Measuring the Latitude and Longitude | Overview Methods
    The latitude is the angular distance of the sun from vertical found by measuring the position on Earth from the position of the sun As a point of reference, 0° is straight into the sky and 90
  • Quaternion distance - Mathematics Stack Exchange
    $\begingroup$ According to ["Metrics for 3D rotations: Comparison and Analysis"][1] which compares a number of metrics, you might want to use the geodesic distance of the normed quaternions, since these lie on the unit 3-sphere (the euclidean distance is not appropriate there) It so happens that it is exactly the formula for $\theta$ that
  • What is angular distance in geography? | Homework. Study. com
    Objects are measured in the sky using things like angular size and distance Explore the celestial sphere, angles, degrees, angular distance, and size, and learn a neat trick for measuring objects in the sky
  • geometry - calculating perpendicular and angular distance between line . . .
    The angular distance looks to be calculated by the dot product of the vectors It has been about $10$ years since linear algebra so I am very rusty on this but I think I can get a handle on this one hopefully
