7. Abbreviation of Levenberg-Marquardt algorithm. It is the most widely used nonlinear least squares algorithm, and the Chinese name is Levenberg-Marquardt method. It is an algorithm that uses gradients to find the maximum (minimum) value. To put it figuratively, it is a kind of "hill climbing" method. It has the advantages of both gradient method and Newton method. When λ is small, the step size is equal to the step size of Newton's method. When λ is large, the step size is approximately equal to the step size of the gradient descent method.

Others Meaning

Unit of luminous flux. A point light source with a luminous intensity of 1 candela (cd) emits a luminous flux of "1 lumen" within a unit solid angle (1 steradian). English abbreviation (lm).

To put it simply, the so-called lumen refers to the brightness of a candle one meter away. The luminous efficiency of an ordinary 40-watt incandescent light bulb is approximately 10 lumens per watt, so Can emit 400 lumens of light. A 40-watt incandescent lamp has a luminous flux of 340 lumens at 220 volts. Luminous flux describes the ability of light source radiation to produce visual response per unit time. The unit is lumens, also called brightness. The unit for expressing the luminous flux of a projector is ANSI lumens. ANSI lumens is the standard for measuring the luminous flux of projectors established by the American National Standards Institute. It measures the illumination at each point at the nine intersections of the "field" shape on the screen, multiplies it by the area, and then calculates the nine The average of the points is the ANSI lumens of the projector. The higher the lumen value, the brighter it is. The higher the brightness, the less need to turn off the lights during projection.

LM is the abbreviation of Lagrange Multiplier Method

LM is also the abbreviation of civilians (rioters) in "Please Close Your Eyes When Dark" (game). [1]
