CVI is an algorithm for constructing implied volatility surfaces that is framed as a convex optimisation problem. As such, it is suitable to be processed by modern optimisation solvers like CVXPY, ...

New brain-computer interface AI model improves real-world EEG data while advancing Zyphra's mission to develop human-aligned superintelligenceSAN ...

This paper presents a non-iterative regularized inverse solution to the image interpolation problem. This solution is based on the segmentation of the image to be interpolated into overlapping blocks ...

The PDF 2.0 spec in section 7.10.2 explains that Type 0 functions can use spline interpolation for the sample data. This is controlled by the /Order field in the Type 0 function dictionary (Table 39).

PyHarm is a PyTorch module designed for efficient polyharmonic spline interpolation. Leveraging GPU acceleration, this implementation excels in performance, making it well-suited for large-scale ...

Abstract: The task of reconstructing smooth signals from streamed data in the form of signal samples arises in various applications. This work addresses such a task subject to a zero-delay response; ...

Interpolation is a mathematical tool used to estimate values that are not directly available in a dataset. Excel provides an easy way to perform interpolation through its powerful formula ecosphere.
