Background:

Cancer remains a significant global health challenge, with traditional therapies like radiotherapy and chemotherapy being costly and having adverse side effects.
Anticancer peptides (ACPs) offer promising therapeutic potential for tumors, but their identification through experimental methods is time-consuming and expensive.
Machine learning approaches can aid in ACP recognition by analyzing feature vectors, but high-dimensional features often lead to poor model performance.

Purpose of the Study:

To develop a more efficient and accurate machine learning model for identifying anticancer peptides (ACPs).
To address the challenge of poor model performance associated with high-dimensional features in ACP recognition.
To propose a reduced-dimensionality feature model that maintains or improves recognition performance.

Main Methods:

Development of a novel 19-dimensional feature model based on anticancer peptide sequences.
Extraction of feature vectors from ACP sequences for machine learning model training.
Comparison of the proposed model's performance against existing methods for ACP identification.

Main Results:

The proposed 19-dimensional feature model demonstrates lower dimensionality and superior performance compared to existing methods for ACP recognition.
A secondary model with a reduced number of dimensions and acceptable performance was also identified.
The identified low-dimensional features may represent key characteristics of anticancer peptides.

Conclusions:

The developed 19-dimensional feature model provides an effective and efficient approach for identifying anticancer peptides.
The findings suggest that a reduced set of features can accurately represent ACPs, potentially simplifying future recognition models.
This work contributes to advancing the application of ACPs in cancer therapy by improving identification accuracy and efficiency.
