Tool Introduction & Use Cases
Gradient Boosting Machine Classification is primarily used for bioinformatics analysis.
GBM is a powerful ensemble learning algorithm that builds multiple weak learners through gradient boosting. Sample names must contain group information in the format: SampleID_Group (e.g., GSM123_control, GSM124_treat). The tool supports custom cross-validation parameters and generates high-quality gene importance gradient plots.
Main Use Cases:
- Explore data patterns and support subsequent in-depth analysis
Key Features:
- Standardized processing and result export
- Key charts and table output
- Can be used as input for subsequent analysis
Parameter Details
| Parameter | Meaning & Recommendations | Settings |
|---|---|---|
| Differential Gene Expression Matrix | 差异基因表达矩阵文件，样本名需包含分组信息（格式：SampleID_Group） | Required Default: None |
| Cross-Validation Method | Analysis Method Selection: Different methods have different distribution assumptions and robustness. Recommendation: For RNA-seq differential analysis, use DESeq2/edgeR; for microarrays, use limma; for enrichment, use hypergeometric/ORA or GSEA. | Optional Default: repeatedcv |
| CV Number | 交叉验证的折数 | Optional Default: 4 |
| CV Repeats | 重复交叉验证的次数 | Optional Default: 4 |
| Figure Size | 图片尺寸设置，格式：高*宽 | Optional Default: 6*10 |
Input File Requirements
Please ensure your input file format is correct, as this is fundamental to successful analysis. Typically, you need to provide a data matrix containing gene/protein expression values.
This tool does not currently provide sample files. Please refer to the common format: typically CSV or TXT files with the first column as gene/protein IDs, followed by expression values for each sample.
Frequently Asked Questions
Q: How long does the analysis take?
A: Estimated execution time is approximately 600 seconds, depending on your data size and current server load.
Q: What if the analysis fails?
A: If the analysis fails, your credits will not be deducted. First, check if your input file format matches the sample file, or adjust parameters based on error messages. If the problem persists, please contact us through the page's feedback function.
