3. Installation 🧶 🔧

To install all dependencies, run (make a conda or python virtual environment if needed, optionally):

pip install -r requirements.txt

To install just the essentials needed, run:

pip install yfinance numpy tensorflow scikit-learn

4. Data Fetching 🥽

Data is fetched using the yfinance library for real-world financial data.

import yfinance as yf

def fetch_data(ticker, start_date, end_date):
    return yf.download(ticker, start=start_date, end=end_date)['Close'].values

5. Data Preprocessing 🎼

Data is preprocessed to create training and testing datasets, which are then fed into machine learning models.

import numpy as np

def create_dataset(data, look_back=1):
    X, Y = [], []
    for i in range(len(data) - look_back - 1):
        a = data[i:(i + look_back)]
        X.append(a)
        Y.append(data[i + look_back])
    return np.array(X), np.array(Y)

6. Usage 🛬 🛫

Navigate to the respective folder and run the Python script for the model you're interested in.

python script_name.py

7. Models Explained 🗺️

1. Supervised Learning Models 🏗️

1.1 Linear Regression 🎢

Linear Regression tries to fit a linear equation to the data, providing a straightforward and effective method for simple predictive tasks.

1.2 Logistic Regression 🛟

Logistic Regression is traditionally used for classification problems but has been adapted here for regression tasks.

1.3 Naive Bayes ⛱️

Naive Bayes is particularly useful when you have a small dataset and is based on Bayes' theorem.

1.4 Random Forest 🛤️

Random Forest combines multiple decision trees to make a more robust and accurate prediction model.

2. Unsupervised Learning Models 🛸

2.1 Clustering (K-means) 🏟️

K-means clustering is used to partition data into groups based on feature similarity.

2.2 Dimensionality Reduction (PCA) 🚧

PCA is used to reduce the number of features in a dataset while retaining the most relevant information.

3. Deep Learning Models 🛰️

3.1 Supervised Deep Learning Models 🚉

3.1.1 Recurrent Neural Networks (RNNs/LSTM) 🌌

Recurrent Neural Networks, particularly using Long Short-Term Memory (LSTM) units, are highly effective for sequence prediction problems. In finance, they can be used for time-series forecasting like stock price predictions.

3.1.2 Convolutional Neural Networks (CNNs) 📱

Convolutional Neural Networks are primarily used in image recognition but can also be applied in finance for pattern recognition in price charts or for processing alternative data types like satellite images for agriculture commodity predictions.

3.2 Unsupervised Deep Learning Models 🎛️

3.2.1 Autoencoders 📻

Autoencoders are used for anomaly detection in financial data, identifying unusual patterns that do not conform to expected behavior.

3.2.2 Generative Adversarial Networks (GANs) ⏲️

GANs are used for simulating different market conditions, helping in risk assessment for various investment strategies.

4. Reinforcement Learning Models 🔋

4.1 Q-Learning 🔌

Q-Learning is a type of model-free reinforcement learning algorithm used here for stock trading.

8. Beyond The Models: Real-World Applications in Finance 💸

In addition to the core machine learning models that form the backbone of this repository, we'll explore practical applications that span various dimensions of the financial sector. Below is a snapshot of the project's tree structure that gives you an idea of what these applications are:

│   ├── compliance_and_regulatory
│   ├── real_estate
│   ├── supply_chain_finance
│   ├── invoice_management
│   └── cash_management

From risk management to blockchain and cryptocurrency, from venture capital to investment banking, and from asset management to personal financial management, we aim to cover a wide array of use-cases. Each of these applications is backed by one or more of the machine learning models described earlier in the repository.

Note: The list of applications is not exhaustive, and the project is a work in progress. While I aim to continually update it with new techniques and applications, there might be instances where certain modules may be added or removed based on their relevance and effectiveness.
