Relative Frequency Histogram

Relative Frequency Histogram

The relative frequency depicts the proportion of data points that have each value. The frequency tells the number of data points that have each value. Like the histogram, a relative frequency histogram also has the same shape with a horizontal scale (the x-axis), but the vertical scale (the y-axis) is marked with relative frequencies (percentages of the whole) instead of actual frequencies. A relative frequency histogram is a graphical representation of a frequency distribution where the...

Histogram

Histogram

The histogram is a graphical representation in the x-y form of data distribution in a data set. The horizontal x-axis is labeled with what the data represents (for instance, distance from your home to school). The vertical y-axis is labeled either frequency or relative frequency (or percent frequency or probability).
A histogram graph consists of contiguous (adjoining) boxes. The heights of the bars correspond to frequency values. The graph will have the same shape with respective labels. The...

Digital pathology
Artificial intelligence
Computer vision

Background:

Multiple Instance Learning (MIL) is crucial for pathological image classification with limited annotations.
Existing whole slide image (WSI) analysis methods struggle to account for sample complexity, hindering clinical deep learning applications.
A morphological fitting bottleneck limits the performance of current MIL approaches across diverse clinical settings.

Purpose of the Study:

To introduce Complexity-Calibrated MIL (CoCaMIL) for improved WSI classification and difficulty grading.
To address the limitations of existing methods by integrating sample complexity into morphological distribution construction.
To enhance the clinical applicability of deep learning in digital pathology.

Main Methods:

Developed an image-text contrastive pretraining framework to jointly learn multiple complexity factors (e.g., blur, stain, brightness).
Implemented a complexity calibration method to create a distance-prioritized feature distribution, mitigating focus on overly difficult samples.
CoCaMIL synergistically combines morphological distribution with key complexity factors for WSI analysis.

Main Results:

CoCaMIL achieved state-of-the-art classification performance on three large-scale benchmarks.
The method established a reliable system for grading sample difficulty in WSI.
Demonstrated enhanced morphological distribution fitting by incorporating complexity factors.

Conclusions:

CoCaMIL represents a novel approach to WSI morphological representation by integrating complexity factors.
This method offers a new perspective for broadening the clinical use of deep learning in digital pathology.
The proposed framework enhances the robustness and accuracy of MIL for pathological image analysis.
