convex nails

There is no systematic study of mathematical optimization, but these tools and techniques are commonly used in machine learning, and the most common optimization in machine learning is convex optimization, which can refer to Ng's teaching materials: http://cs229.stanford.edu/section/ Cs229-cvxopt.pdf, from which we can understand some of the convex optimization concepts, such as

whole body organs. 2, promote the normal operation of organs qi and blood. 3, resist external evil (immune function). 4, longevity anti-aging substances. 5, genetic material. Chinese medicine has a sentence: fine enough people strong, fine weak people disease, fine few people old, fine people die. This shows that the essence of vitality is important. In daily life, restore the essence of vitality in time, the maintenance of good health, conducive to our health. When energy is low, the important

Convex Function A convex function is a continuous function whose value at the midpoint of every interval in its domain does not exceed the Arithmetic mean of its values at the ends of the interval. More generally, a function was convex on a interval if to any two points and where, (Rudin 1976, p. Cf. Gradshteyn and Ryzhik, p. 1132). If has a second derivative in,

Identification and governance A disease can be caused by a's own disease, systemic disease, a change in the finger, toe A, or a skin disease around a affected finger, toe. Therefore, observing the changes of fingers and Phalanx (especially nails) is of great significance for assisting in the diagnosis and treatment of some diseases, especially some skin diseases. This article focuses on the lesions of skin diseases, and describes the treatment of TCM

Convex bag (convex Hull)In graphics, convex hull is a very important concept. In brief, n points are given in the plane to find a convex polygon composed of some points as vertices, which can enclose all n points.It was much like nailing n nails on a piece of wood, and then

a spatial point set. Some algorithms can easily find the convex hull of a point set in the Euclidean space of any dimension. The convex hull has a beautiful and practical nature. We can use the convex hull to make effective the information contained in a messy point set.Summary ========================================================== ====================

Pattern: Spotted grain anomaly　　There are vertical lines that may not digest well. Many people's nails have a dense or sparse ridge-like vertical lines, which is the function of the digestive system is not good embodiment. If the vertical lines are not very small, just pay attention to the regular diet, nutrition balance can be. There are also experts who believe that the edge of the nails may be calcium de

"Title description"There is a triangular plank, vertical upright, with n (n+1)/2 nails on it, and (n+1) a lattice (when n=5 1). The distance between each nail and the surrounding nail is equal to D, and the width of each lattice is equal to D, and each lattice in addition to the leftmost and most right side of the grid is facing the bottom row of nails.Let a small ball center with a diameter of slightly less than D is on the top of the nail on the boa

Given a (finite) Point Set (a group of points) on a plane, the convex hull of this point set is a convex polygon that contains the minimum area of all points in the point set. In a two-dimensional Euclidean space, a convex bag can be imagined as a rubber circle containing just all vertices. This can be vividly thought like this: place some unmovable wooden piles

Preface: First, what is the convex package.Suppose the plane has a total of 13 points, p0~p12 some points as a polygon, so that the polygon can be "wrapped" all the points. When this polygon is a convex polygon, we call it "convex package". The following figure: Then, what is the convex package problem.We put these po

From the perspective of Traditional Chinese Medicine, if the crescent moon on a person's fingernails is big and shiny, it indicates that the blood of the person is rich. If the crescent moon becomes smaller or disappears gradually, it indicates that the blood and blood of the human body decline, the health status is not as good as before.Traditional Chinese medicine indeed records that the White Crescent can be used to determine whether a person's heart function is good. Traditional Chinese Medi

To use map nails, we first need to create an annotation class for map nails.

(1) What is a half-month mark?There is a white arc mark at 1/5 under the nail, which is a half-month mark, which is also called the small sun.The half-month mark of nails is the line between yin and yang meridians, and represents the essence of the human body. It is also known as the Health circle.The development of the half-month mark is affected by the nutrition, environment, and physical quality. When the digestion and absorption functions are poor
