Fréchet inception distance. The Fréchet inception distance (FID) is a metric used to assess the quality of images created by a generative model, like a generative adversarial network (GAN) [1] or a diffusion model [2][3]. The FID compares the distribution of generated images with the distribution of a set of real images (a "ground truth" set).
The model, the largest at the time, was 6.5 metres (21 feet) high, weighs 544 kilograms (1,199 pounds), was made from 19,507 pieces, 50,560 nuts and bolts, and took 1,239 hours to construct. [32] At this mass and size, some deviation from Meccano-only parts was a necessity, to prevent it collapsing (mainly in the structural spokes).
Ship models: This was a standard size for ship models produced by Revell and Italeri but they have moved from it. 1:700: 0.435 mm: Ship models: This is the scale that most manufacturer chose to produce the largest series of waterline plastic model ships and submarines. Full hull models are popular in that scale as well. 1:600: 0.508 mm: Ship models
Both models can be described as 15 mm, but the real world sizes depend on the size of the reference humanoid. In practice, the reference humanoid is generally assumed to be the idea of the average height of the human male, within a 6-inch (15 cm) interval between 5.5 and 6 feet (168 and 183 cm), unless otherwise indicated by the designer.
In mathematics and its applications, the signed distance function or signed distance field (SDF) is the orthogonal distance of a given point x to the boundary of a set Ω in a metric space (such as the surface of a geometric shape), with the sign determined by whether or not x is in the interior of Ω. The function has positive values at points ...
Structural similarity index measure. The structural similarity index measure (SSIM) is a method for predicting the perceived quality of digital television and cinematic pictures, as well as other kinds of digital images and videos. It is also used for measuring the similarity between two images. The SSIM index is a full reference metric; in ...
The dominant scale used in the United States for models of "standard gauge" trains running on 45 mm (1.772 in) track, even though 1:32 is more prototypically correct. 1:29 represents standard gauge using 2 in (50.8 mm) gauge track, the original gauge 2. This fell into disuse as gauge 1 at 1.75 inch was very close.
BS 93:2008 — British Association (B.A.) screw threads — Requirements. The angle of the thread is 47.5° [4]: 2 and the depth of thread is 0.6 times the pitch with rounded tops and bottoms. Thus, the shortening at the crest and root is given by 0.26817 p with a radius of 0.18083 p at both crest and root. [4]: 2 The 1884 report specifies a ...
