Advances in Financial Machine Learning

finance_ml

Python implementations of Machine Learning helper functions for Quantiative Finance based on books, Advances in Financial Machine Learning and Machine Learning for Asset Managers , written by Marcos Lopez de Prado.

Installation

Excute the following command

python setup.py install

or

Simply add your/path/to/finace_ml to your PYTHONPATH.

Implementation

The following functions are implemented:

• Labeling
• Multiporcessing
• Sampling
• Feature Selection
• Asset Allcation
• Breakout Detection

Examples

Some of example notebooks are found under the folder MLAssetManagers.

multiprocessing

Parallel computing using multiprocessing library. Here is the example of applying function to each element with parallelization.

import pandas as pd
import numpy as np

def apply_func(x):
    return x ** 2

def func(df, timestamps, f):
    df_ = df.loc[timestamps]
    for idx, x in df_.items():
        df_.loc[idx] = f(x)
    return df_
    
df = pd.Series(np.random.randn(10000))
from finance_ml.multiprocessing import mp_pandas_obj

results = mp_pandas_obj(func, pd_obj=('timestamps', df.index),
                        num_threads=24, df=df, f=apply_func)
print(results.head())

Output:

0    0.449278
1    1.411846
2    0.157630
3    4.949410
4    0.601459
