This study introduces the ACTIVITY computer system for predicting functional site activity in nucleotide sequences using fuzzy logic. The system generates reliable prediction programs, outperforming common methods.

Area of Science:

  • Bioinformatics
  • Computational Biology
  • Machine Learning

Background:

  • Predicting functional site activity in nucleotide sequences is crucial for biological research.
  • Existing methods for sequence-based activity prediction have limitations.

Purpose of the Study:

  • To develop a novel computational system, ACTIVITY, for predicting nucleotide sequence activity.
  • To leverage Zadeh's fuzzy logic and decision-making theory for improved prediction accuracy.

Main Methods:

  • The ACTIVITY system analyzes nucleotide sequences with known activities.
  • It employs fuzzy logic to determine the optimal "sequence-->activity" regression model.
  • The determined model is converted into a predictive program.
