Goertzel算法是数字信号处理(DSP)中的一项技术,为有效评估离散傅里叶变换(DFT)的各个项提供了一种方法。我创建了一个具有多个频率f0,f1和f2的正弦波,并加了一些白噪声。之后,我将Goertzel功能应用于嘈杂的信号,计算了每个频率的检测概率,并绘制了平均概率与检测到的所有频率的关系图。

ESP_DNN Graph Convolutional Deep Neural Network for Electrostatic Potential Surface Prediction in DFT(MATLAB Source Code)
ESP-DNN: Graph Convolutional Deep Neural Network for Predicting Electrostatic Potential Surfaces from DFT Calculations
This repository contains trained models and code designed for generating ligands and proteins, creating electrostatic potential (ESP) surfaces that closely resemble DFT-quality molecular surfaces. The PQR files generated by our model include atomic charges and dipole-like atomic features, such as lone pairs, σ-conjugation, and p-orbitals. To generate ligand PQR files, a graph convolutional deep neural network (DNN) model was trained on about 100,000 molecules with ESP surfaces derived from DFT calculations.
For proteins, parameterized charges of amino acids were used, ensuring compatibility with the ligand ESP surfaces generated by the DNN model. For more detailed methods and validation information, refer to the full documentation.
System Requirements
The program can only run on 64-bit Linux operating systems.
Installation Instructions
To run ESP-DNN, you will need to:1. Clone this repository.2. Set up Python and required dependencies.3. (Optional) Install additional packages.
The package has been developed and tested with Python 2.7 and the following third-party libraries:- rdkit == 2018.09.3- keras == 2.2.4- tensorflow == 1.10.0- num
