    Depth Perception and Spatial Vision

    Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

    We introduce MAPLE, a new nonlinear dimensionality reduction technique that improves upon UMAP by using self-supervised learning for better manifold modeling. MAPLE enhances data visualization for complex datasets like biological and image data.

    Area of Science:

    • Machine Learning
    • Data Science
    • Bioinformatics

    Background:

    • Nonlinear dimensionality reduction is crucial for visualizing high-dimensional data.
    • Existing methods like UMAP may struggle with complex manifold structures and intra-cluster variance.
    • Improved manifold modeling is needed for clearer data representation.

    Purpose of the Study:

    • To introduce MAPLE, a novel nonlinear dimensionality reduction method.
    • To enhance manifold modeling using self-supervised learning and maximum manifold capacity representations (MMCRs).
    • To demonstrate MAPLE's effectiveness on high-dimensional biological and image data.

    Main Methods:

    • Developed MAPLE, a self-supervised learning approach for dimensionality reduction.
    • Utilized maximum manifold capacity representations (MMCRs) to untangle complex manifolds.

    Related Experiment Videos

  • Employed qualitative and quantitative evaluations to compare MAPLE with UMAP.

    • Main Results:

    • MAPLE demonstrates improved manifold modeling compared to UMAP.
    • The method effectively handles high-dimensional data with substantial intra-cluster variance and curved structures.
    • MAPLE achieves clearer visual cluster separations and finer subcluster resolution.

    Conclusions:

    • MAPLE offers enhanced dimensionality reduction by improving manifold modeling.
    • The technique provides superior visualization of complex datasets, particularly biological and image data.
    • MAPLE maintains computational tractability while delivering improved performance over UMAP.
