Econophysics is an interdisciplinary field that incorporates physics to address pheno-
mena within economic systems, with one key focus being the analysis of financial mar-
kets. Financial market prediction is crucial for investors’ financial decision-making.
Approaches to financial market prediction include statistical models, machine learning,
and deep learning methods in artificial intelligence. However, the complexity and high
dimensionality of financial market data often hinder model performance. Therefore, a
machine learning model known as the Restricted Boltzmann Machine (RBM) is pro-
posed for feature extracting. This study aims to analyze the impact of RBM hyper-
parameters on stock price trend prediction and to compare Gaussian-Bernoulli RBM
with Bernoulli RBM. The study involves using RBMs to predict stock price trends for
four coal sector stocks, namely PTBA, ITMG, KKGI, and BUMI, utilizing Support
Vector Machine (SVM), Random Forest, Multi-Layer Perceptron Classifier, and Long
Short-Term Memory (LSTM). The prediction results are evaluated based on accuracy,
precision, and negative predictive value using evaluation matrices. The classification
model performance is also reviewed using the receiver operating characteristic (ROC)
curve and its area under the curve (AUC). The study concludes that optimizing RBM
hyperparameters affects the resulting accuracy, and Bernoulli RBM yields better resul-
ts than Gaussian-Bernoulli RBM. However, some stock data and classification models
show no significant impact from optimized hyperparameters, due to factors such as da-
ta characteristics, hyperparameter options in fine-tuning searches, and the selection of
parameters to optimize.
