A computer-implemented method for visualizing and optionally clustering single cell-type data using a hierarchical structure, enabling interactive selection and manipulation of classes through a graphical user interface, allowing users to explore data without prior knowledge of specific populations, and facilitating intuitive data representation changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated clustering methods are used to eliminate manual gating, then objectivity and reproducibility improve, but interpretability and user understanding of data structure deteriorate
Solution Approach 1:
The patent introduces an interactive visualization interface as an intermediary between automated clustering algorithms and users. This interface displays clustered data points with hierarchical groupings and allows users to explore cluster structures, select regions of interest, and interpret results visually, thereby recovering interpretability while maintaining automated clustering reproducibility
Solution Approach 2:
The system implements feedback mechanisms where user interactions with the visualization (such as selecting regions, adjusting parameters, or exploring clusters) provide feedback that refines and clarifies the clustering results. This iterative feedback loop enhances user understanding and interpretability of the automated clustering output
2Loss of information
If manual gating is used for data analysis, then interpretability and user control are maintained, but time consumption and labor intensity increase
Solution Approach 1:
The patent applies preliminary automated clustering to organize data points into groups before user analysis. This preliminary action creates a structured foundation that reduces the time and effort required for manual gating, while the subsequent interactive visualization allows users to efficiently review and interpret the pre-organized data
Solution Approach 2:
The system segments the large dataset into smaller, manageable clusters automatically. This segmentation reduces the complexity of manual analysis by breaking down the overwhelming task of analyzing all data points into reviewing and interpreting smaller, organized groups, thereby reducing time consumption while maintaining interpretability
3Measurement precision
If the number of cytometric parameters increases, then measurement precision and biological insight improve, but data complexity and analysis difficulty increase
Solution Approach 1:
The patent addresses high-dimensional data complexity by projecting clustered data points into lower-dimensional visual spaces while preserving cluster structures. The interactive visualization displays data in 2D or 3D plots where users can explore relationships between multiple parameters through interactive filtering and parameter selection, making high-dimensional data comprehensible without losing measurement precision
Solution Approach 2:
The system applies local quality by allowing users to focus on specific regions or clusters of interest within the high-dimensional data space. The interactive visualization enables users to select and examine particular clusters in detail, adjusting parameter displays and exploration depth locally, rather than requiring comprehension of the entire high-dimensional dataset at once
