Classification of Bones

Classification of Bones

The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The long...

Cancer Survival Analysis

Cancer Survival Analysis

Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Adaptive Mechanisms in Cancer Cells

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Mouse Models of Cancer Study

Mouse Models of Cancer Study

Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

Background:

Accurate multi-class molecular cancer classification is crucial for clinical applications.
Existing methods require robust statistical approaches for high-dimensional genomic data.
Classifying cancer types necessitates efficient algorithms that can handle thousands of genes.

Purpose of the Study:

To present a novel functional gradient descent boosting algorithm, HingeBoost, for multi-class cancer classification.
To extend the binary HingeBoost algorithm to the multi-class setting directly, avoiding problem reduction.
To introduce Twin HingeBoost for enhanced feature selection behavior.

Main Methods:

Minimizing a multi-class hinge loss using a boosting technique.
Implementing the Bayes decision rule for theoretical properties and a unifying framework.
Evaluating HingeBoost and Twin HingeBoost using simulated, benchmark, and cancer gene expression datasets.

Main Results:

Multi-class HingeBoost demonstrated accurate predictions compared to alternative methods, particularly with high-dimensional data.
The algorithm achieved accurate or comparable predictions in two cancer gene expression classification tasks.
Twin HingeBoost exhibited improved feature selection by reducing ineffective covariates.

Conclusions:

HingeBoost serves as a potent tool for multi-classification challenges in bioinformatics.
Twin HingeBoost offers enhanced classification accuracy and feature selection capabilities.
