“…Correlation analysis was conducted to understand the relationships between variables, using the Pearson correlation coe cient formula to quantify the strength and direction of these relationships [7]. Feature selection was then applied to re ne the model by identifying and retaining only those features with signi cant predictive power, thereby enhancing computational e ciency and reducing the risk of over tting [5].…”

The emergence of Bitcoin as a decentralized digital currency has underscored the importance of developing advanced techniques for predicting its price fluctuations. This study evaluates the predictive power of Bitcoin-related Google search volumes and Twitter sentiment analysis within short time frames. By leveraging machine learning algorithms and opinion mining, we identify correlations between online behaviors and Bitcoin price movements. Our methodology encompasses data sourcing, preprocessing, exploratory analysis, feature selection using Correlation Analysis, F-regression, Shapley values, and price prediction with a Long Short-Term Memory (LSTM) model. Findings reveal that Google search data, compared to Twitter sentiment, significantly enhances model accuracy and reduces prediction errors. The study suggests future research to investigate other search engines and online news sentiment, acknowledging limitations in data quality and accessibility of historical Twitter data.

“…However, given the small size of data used in this study, we choose to focus on the Spearman correlation coefficient. Indeed, the correlation analysis has been proven to provide relevant features in the case of machine learning, see for instance [61]. The choice of the Spearman correlation rather than the Pearson is due to the fact that the relationship between the rheological parameters and the physico-chemical components is rather nonlinear.…”

“…Although this method reduces the time to find parameter values, there is a limitation that the best combination of values cannot be found, since it does not take into account all possible combinations of the parameter values. Using the above method, a study predicted future bitcoin price with two hyperparameters, the length of the input sequence and the number of hidden layer units [12]. They found an optimal value of the number of hidden layer units.…”

Since bitcoin has gained recognition as a valuable asset, researchers have begun to use machine learning to predict bitcoin price. However, because of the impractical cost of hyperparameter optimization, it is greatly challenging to make accurate predictions. In this paper, we analyze the prediction performance trends under various hyperparameter configurations to help them identify the optimal hyperparameter combination with little effort. We employ two datasets which have different time periods with the same bitcoin price to analyze the prediction performance based on the similarity between the data used for learning and future data. With them, we measure the loss rates between predicted values and real price by adjusting the values of three representative hyperparameters. Through the analysis, we show that distinct hyperparameter configurations are needed for a high prediction accuracy according to the similarity between the data used for learning and the future data. Based on the result, we propose a direction for the hyperparameter optimization of the bitcoin price prediction showing a high accuracy.
