About The Project

Diagnostipy is a open-source, Python library for rule-based diagnosis and evaluation. It allows users to define rules with conditions and weights, manage rulesets, and evaluate input data using customizable scoring and confidence functions.

Features

• Define rules using SymptomRule with customizable conditions, weights, and criticality.
• Manage collections of rules via SymptomRuleset.
• Evaluate data using built-in or custom scoring and confidence functions with Evaluator.
• Flexible and extensible API.

When Should I Use Diagnostipy?

• When interpretability is more important than accuracy, and you need a clear, rules-based system to explain decision-making
• If you lack access to large datasets for training machine learning models but still require a structured evaluation or diagnostic tool
• When collaborating with domain experts to formalize diagnostic or evaluation criteria without a data-driven approach
• When working in regulated industries or domains where decisions must be auditable and transparent
• For quick prototyping of logic-based systems without the overhead of complex data pipelines

Usage

Define Rules

from diagnostipy.core.models.symptom_rule import SymptomRule

rule_high_fever = SymptomRule(
    name="High Fever",
    weight=6.0,
    critical=True,
    apply_condition=lambda data: data.get("temperature", 0) >= 39,
)

rule_cough = SymptomRule(
    name="Persistent Cough",
    weight=4.0,
    critical=False,
    apply_condition=lambda data: data.get("cough", False),
)

rule_sore_throat = SymptomRule(
    name="Sore Throat",
    weight=5.0,
    critical=True,
    apply_condition=lambda data: data.get("sore_throat", False),
)

Create Ruleset

from diagnostipy import SymptomRuleset

ruleset = SymptomRuleset([rule_high_fever, rule_cough, rule_sore_throat])

Evaluate data

from diagnostipy import Evaluator

data = {
    "temperature": 39.5,
    "cough": True,
    "sore_throat": False,
}

evaluator = Evaluator(ruleset)
results = evaluator.run(data=data)

print(results)

total_score=10.0 label='High' confidence=0.8333333333333334 metadata=None

Roadmap

• Add support for more built-in confidence functions.
• Improve error handling.
• Expand the API to include more user-friendly options.
