Benchmarks

Performance evaluation across prosodic classes

Performance evaluation across padyam types

Our algorithm achieves 91.73% accuracy on the proposed Chandassu Score.

Usage

Install package using

pip install chandassu

Check padyam

from chandassu.laghuvu_guruvu import LaghuvuGuruvu
from chandassu.padya_bhedam import check_padyam

data= """తొండము నేక దంతమును తోరపు బొజ్జయు వామ హస్తమున్
మెండుగ మ్రోయు గజ్జెలును మెల్లని చూపులు మందహాసమున్
కొండొక గుజ్జు రూపమున కోరిన విద్యలకెల్ల నొజ్జవై
యుండెడి పార్వతీ తనయ యోయి గణాధిప నీకు మ్రొక్కెదన్"""

# Generate LaghuvuGuruvu Sequence
lg_data= LaghuvuGuruvu(data= data).generate()

score= check_padyam( 
                        lg_data= lg_data ,
                        type= "vutpalamaala",
                        return_micro_score= True, 
                        verbose= False
                    )

print(scores)

Computational Architecture

• nidhi.py: Telugu alphabet classification with phonological categorizations
  
• panimuttu.py: Vowel-consonant operations utility functions
  
• laghuvu_guruvu.py: Prosodic analysis engine with tokenizer and syllabic weight classifier
  
• ganam.py: Pattern repository mapping LaghuvuGuruvu sequences to metrical units
  
• padyam_config.py: Configuration database for padyam type constraints and rules
  
• check_lakshanam.py: Validation module for yati (caesura) and prasa (alliteration)
  
• padya_bhedam.py: Main integration module for metrical assessment and evaluation
