Last updated 1 year ago

The choice of machine learning algorithms is critical for opcode analysis. For this purpose, ensemble methods like Random Forests or gradient boosting algorithms are often preferred due to their robustness and ability to handle imbalanced data, which is common in security-related contexts. Additionally, neural network architectures, particularly those designed for sequence data like LSTM (Long Short-Term Memory), can be effective in understanding the sequential nature of opcodes.

These algorithms are chosen because they can capture the complex patterns and dependencies in opcode sequences that may indicate malicious behavior. For instance, Random Forests offer interpretability through feature importance scores, while LSTM networks can capture long-range dependencies in opcode sequences, which is crucial for detecting sophisticated contract exploits.
