In the intricate world of asset management, the ability to apply machine learning techniques can significantly enhance decision-making processes. This tutorial will guide you through installing the necessary library and implementing a specific method to find the optimal bandwidth for Kernel Density Estimation (KDE). We will utilize concepts from the book “Machine Learning for Asset Managers” by Prof. Marcos López de Prado. Let’s dive right in!
Installation of the Required Library
To begin, you first need to install the library that contains the functions you wish to use. This library is hosted on GitHub and can be easily installed using pip. Follow the steps below to get started:
- Open your command line interface.
- Enter the following command:
pip install -U git+https://github.com/emoen/Machine-Learning-for-Asset-Managers.gitUsing the Library to Find Optimal Bandwidth
Once the library is successfully installed, you can proceed to implement the function to find the optimal bandwidth for KDE. The method we will use is findOptimalBWidth from the imported module. Here’s how it works:
from Machine_Learning_for_Asset_Managers import ch2_fitKDE_find_best_bandwidth as c
import numpy as np
bandwidth = c.findOptimalBWidth(np.asarray([21, 3]))
print(f'bandwidth: {bandwidth}') # Output: bandwidth: 10.0
Breaking Down the Code: An Analogy
Imagine a busy restaurant with many chefs (data points). Each chef is uniquely creating delicious dishes (information). In order to serve the best meal to the customers (desired outcome), the restaurant manager (the function) needs to determine how much spice (bandwidth) to add to the dish, ensuring it’s neither too bland (underfitting) nor too spicy (overfitting).
The function findOptimalBWidth acts like this restaurant manager. It carefully analyzes the chefs’ approaches (the data points) and suggests an ideal amount of spice (the bandwidth), allowing the dish to captivate the customers’ taste (achieving the best KDE representation of the data).
Troubleshooting Common Issues
While working with this library, you might encounter some common issues. Here are a few troubleshooting tips to assist you:
- If you receive an error during installation, ensure that your pip is up-to-date by running
pip install --upgrade pip. - In case of import errors, double-check that the installation was successful and verify the file structure to ensure the module is correctly placed.
- If the code returns unexpected values, consider the data input. Ensure the numpy array is properly formatted and contains valid values for bandwidth calculation.
