Problem of dimensionality
WebbMany problems in the fields of finance and actuarial science can be transformed into the problem of solving backward stochastic differential equations (BSDE) and partial differential equations (PDE) with jumps, which are often difficult to solve in high-dimensional cases. To solve this problem, this paper applies the deep learning algorithm … WebbSo the model is not able to train with the correct information. That’s why Accuracy decreases. So, after a certain threshold value, when accuracy decreases by increasing the number of features is known as the Curse …
Problem of dimensionality
Did you know?
Dimensionally cursed phenomena occur in domains such as numerical analysis, sampling, combinatorics, machine learning, data mining and databases. The common theme of these problems is that when the dimensionality increases, the volume of the space increases so fast that the available data become sparse. Visa mer The curse of dimensionality refers to various phenomena that arise when analyzing and organizing data in high-dimensional spaces that do not occur in low-dimensional settings such as the three-dimensional Visa mer • Bellman equation • Clustering high-dimensional data • Concentration of measure Visa mer Combinatorics In some problems, each variable can take one of several discrete values, or the range of possible values is divided to give a finite number of possibilities. Taking the variables together, a huge number of combinations of … Visa mer WebbIn calculus, Newton's method (also called Newton–Raphson) is an iterative method for finding the roots of a differentiable function F, which are solutions to the equation F (x) = 0.As such, Newton's method can be applied to the derivative f ′ of a twice-differentiable function f to find the roots of the derivative (solutions to f ′(x) = 0), also known as the …
Webb17 dec. 2024 · When we talk about the curse of dimensionality, we often refer to the difficulty that arises when analysing and organising data in high-dimensional spaces. In this blog, I will talk about a less known problem related to decision trees, which has a lot of similarities to data analytics in high-dimensional spaces.
