Clover MSDAS v1.3 Features & Improvements
- Outliers Detection Module first version release. PCA Reconstruction and Spectra Correlation analysis have been implemented.
- Shapley Values plot includes now a bar plot to show the shapley values mean.
- New file size upload limit is upgrade to 300MB.
- Validation & Identification modules run now asynchronously. You can leave the screen and recover the result later.
- Hyperparameters at classification can be now choosen manually or calculated via autotune algorithm.
- ROC and Precision-Recall curves displayed up to 4 decimals for AUC values and can be downloaded in CSV format.
- Error Rate have been added as a metric.
- LightGBM have been adjusted on how hyperparameters are optimized.
- In the ROC curve table at Biomarker Analysis module, you can click now on the table rows for selecting masses. Once they are selected, a peak matrix can be automatically generated by using those masses.
Stable version v1.0 of Clover MS Data Analysis Software
Major updates
- Multitask mode: Now supervised classifiers run in asynchronous mode. Therefore, the user can leave or close the page/tab safely or work in other tasks, because the result will be there next time the classifier page is accessed.
- Performance improvements: Algorithms now work in dedicated processes.
- Random Forest: Newly optimized hyperparameters are: number of estimators, max features, max tree depth, min split size, min number of samples per leaf.
- LightGBM: Adjustments on hyperparameters optimization. Shapley feature importances optimization.
- Biomarker Analysis: In the ROC curve table, the user can click on the table rows for selecting masses. Once they are selected, a peak matrix can be automatically generated by using those masses as biomarkers.
Minor updates
- TIC normalization: is now performed using the area under the entire spectrum.
- Find Peaks Graph: The user can click on a detected peak for displaying a label with the mass value.
- Biomarker Analysis: When a row is clicked in the ROC curve table, now it is also filtered in the Peak Distribution table.
