Introduction
Automated trading in financial markets has gained additional significance with the advancements of machine learning and deep learning technologies. As the volume and complexity of data increase, machine learning-based trading algorithms are emerging that can provide insights difficult to obtain through traditional methods. This course will explore trading strategies using machine learning and deep learning algorithms, and explain how to utilize TensorBoard for visualizing the embedding space.
1. Basic Concepts of Machine Learning and Deep Learning
Machine Learning (ML) is the technology of creating algorithms that can learn patterns from data to make predictions or decisions. On the other hand, Deep Learning (DL) is a subfield of machine learning based on artificial neural networks, capable of handling more complex and large-scale problems. Each of these technologies plays an essential role in building automated trading systems, contributing to generating trading signals and maximizing performance.
1.1 Machine Learning Algorithms
Machine learning algorithms can be broadly categorized into supervised learning, unsupervised learning, and reinforcement learning. The most commonly used method in trading algorithms is based on supervised learning models. The model is trained through learning from specific input data (e.g., historical stock prices) and the corresponding output (e.g., buy/sell signals).
1.2 Deep Learning Algorithms
Deep learning algorithms utilize neural networks composed of multiple layers of neurons to learn more complex patterns. CNNs (Convolutional Neural Networks) are suitable for image data, while RNNs (Recurrent Neural Networks) or LSTMs (Long Short-Term Memory networks) are ideal for time series data, widely used for stock market predictions.
2. Theoretical Basis of Algorithmic Trading
Algorithmic trading is based on advanced mathematics and statistics to model market movements. These mathematical models generally include time series analysis, regression analysis, probabilistic models, and optimization techniques.
2.1 Time Series Analysis
Time series analysis is used to understand data over time, such as stock prices. It is useful for predicting future price trends based on historical data. While traditional time series models like ARIMA exist, recent models enhance the accuracy of these predictions through machine learning techniques.
2.2 Reinforcement Learning
Reinforcement learning aims for agents to learn optimal behavior strategies through interaction with the environment. In trading, strategies that maximize the value of financial assets can be learned through choices such as buying, selling, and holding.
3. Environment Setup and Data Collection
Setting up an environment for algorithmic trading is very important. We will explore the process of collecting necessary software and price data.
3.1 Development Environment
Python is the most widely used programming language in the fields of machine learning and deep learning. Django and Flask are useful for building web applications, while libraries like Pandas, NumPy, and Scikit-learn are essential for data processing and implementing machine learning models.
3.2 Data Collection
Data needed for trading can be collected through APIs like Yahoo Finance, Alpha Vantage, and Quandl. In addition to price information, various variables such as financial statements, news, and social media data can also be considered.
4. Model Building and Training
This stage involves building and training machine learning and deep learning models based on the collected data. We will explain how to evaluate model performance and optimize it through hyperparameter tuning.
4.1 Data Preprocessing
Preprocessing data is essential to maximize the performance of machine learning models. It is crucial to improve data quality through methods like handling missing values, normalization, and feature selection.
4.2 Model Training
You can train various machine learning models (e.g., Random Forest, SVM) using scikit-learn, and build neural networks using Keras and TensorFlow. Techniques for evaluating model performance will also be introduced in this stage.
5. Embedding Visualization via TensorBoard
TensorBoard is a visualization tool provided by TensorFlow that is useful for systematically tracking the training process visually. It plays a crucial role in monitoring the learning process of machine learning and visualizing results during deep learning model training.
5.1 Getting Started with TensorBoard
We will explain the required installation and setup methods for using TensorBoard. After installing TensorFlow, prepare to visualize in TensorBoard by generating log files.
5.2 Embedding Visualization
During the training process of deep learning models, we visualize embeddings to understand relationships between data points. Techniques like PCA (Principal Component Analysis) or t-SNE (t-Distributed Stochastic Neighbor Embedding) can reduce the structure of high-dimensional data to 2D or 3D for visualization.
5.3 Practical Example
We will build a simple deep learning model using TensorFlow and Keras, and explain how to extract embeddings during the training process and visualize them in TensorBoard step by step. You can run the code and observe the results to visually see the changes.
Conclusion
This course has helped you gain a basic understanding of building automated trading systems using machine learning and deep learning, and learned methods to explore relationships between data through embedding visualization. The importance of algorithmic trading in future financial markets will continue to grow, and data-driven decision-making is expected to become an essential element. I hope that you develop your own trading strategies through continuous learning and experimentation.
