| Medium | GrooveSquid.com (original content) | Medium Difficulty Summary This paper analyzes the genome sequence of Perccottus glenii, a unique fish species capable of surviving freezing temperatures. Traditional biology methods are time-consuming and inaccurate, so machine learning techniques are employed to study gene sequences. Five vectorization methods (ordinal encoding, One-Hot encoding, K-mer encoding) are proposed for handling ultra-long gene sequences. A comparative study identifies the optimal encoding method, which is used to construct four classification models (Random Forest, LightGBM, XGBoost, Decision Tree). The dataset comes from the National Center for Biotechnology Information database, and the optimal model (Random Forest) achieves a classification accuracy of 99.98%. SHAP values are utilized for interpretable analysis, revealing the top 10 features contributing to the model’s accuracy. This demonstrates machine learning can replace traditional manual analysis in identifying genes associated with freeze tolerance. |
| Low | GrooveSquid.com (original content) | Low Difficulty Summary This research looks at the special fish Perccottus glenii that can survive freezing temperatures. Scientists usually take a long time and don’t get accurate results when studying this fish’s genes, so they’re using computer programs to help. They tried different ways to analyze the gene sequences and found one method that works best. Then, they used this method to build four special models that can predict which genes are important for freeze tolerance. The most accurate model worked really well, and by analyzing it, scientists discovered what makes it so good at predicting freeze tolerance. This shows that computers can help scientists understand how this fish adapts to extreme environments. |
