BMINet 0.1.4

Machine Learning and Graph based tool for detecting and analyzing Bone-Muscle Interactions

Introduction of BMINet

Machine learning and network based tool for:

• Classify and predict different disease stages precisely
• Understand machenism using SHAP model explanation
• Detect Bone-Muscle Interact network and detect disease modules

Install

Dependency

• Python>=3.9

Quick install

• Install from pypi: pip install BMINet
• Or install from GitHub:

git clone https://github.com/Spencer-JRWang/BMINet
cd BMINet
pip install .

Example Usage

• First, you should prepare your data (from CT or MRI etc.): Example Data
• Load your data

import pandas as pd
df = pd.read_csv('Example/data.txt', sep='\t')

• Select features

# Load FeatureSelector
from BMINet.Interaction import FeatureSelector
selector = FeatureSelector(core_name="LightGBM")
# Conduct feature selection from df
selected_features = selector.select(df)

core_name should be "LightGBM", "XGBoost" or "CatBoost"

• Build linear formula model

from BMINet.Model import Lasso_Formula
formula = Lasso_Formula(df, disease_pairs=("A", "B"))
print(formula)

Also Ridge, ElasticNet and Simple Linear

• Build stacking model

from BMINet.Interaction import StackingModel
# Load stacking model framework
'''
default: StackingModel(
    base_models = [
            ('LGBM', LGBMClassifier(verbose=-1, n_estimators=1000, max_depth=5)),
            ('XGBoost', XGBClassifier(n_estimators=1000, max_depth=5)),
            ('CatBoost', CatBoostClassifier(verbose=False, iterations=800, max_depth=5))
        ]), 
    meta_model = LogisticRegression()
'''
Model = StackingModel()
best_scores = Model.stacking_model_search(df, selected_features)

Using default base model and meta model, you can also define it yourself

• Predict of each group

# single predict
single_prediction_score = Model.single_predict("A vs B", [...], use_our_model=True)
# multiple predict
multiple_prediction_score = Model.multiple_predict_predict("A vs B", [[...], [...],], use_our_model=True)

If you use use_our model = True, you are predicting disease staged based on our data and model

If you are researching on a brand new project, use use_our_model = False

• Basic machine learning plots

from BMINet.plot import plot_ml_roc
plot_ml_roc(best_scores)
from BMINet.plot import plot_precision_recall
plot_precision_recall(best_scores)
from BMINet.plot import plot_score_histogram
plot_score_histogram(best_scores)
from BMINet.plot import plot_calibration_curve
plot_calibration_curve(best_scores)

• Model Explanation

from BMINet.Interaction import SHAPVisualizer
# Load explanation class and train it
shap_visualizer = SHAPVisualizer(core_name="LightGBM")
shap_visualizer.train_model(df, selected_features)
# The dir you want to save the files
shap_visualizer.plot_shap('./Example')
shap_visualizer.plot_dependence('./Example')

• Network Construction

# Load NetworkConstructor
from BMINet.Interaction import NetworkConstructor
network_constructor = NetworkConstructor(core_name="LightGBM", cutoff = 1.5)

# Construct sub-network list for each group
interactions = network_constructor.construct_network(df, selected_features)
# Construct conmbined network
combined_graph = network_constructor.compose_all(interactions)
# Remove isolated nodes from the network
Graph_BMI = network_constructor.remove_isolated_nodes(combined_graph)
# Save to .graphml file
network_constructor.save_graph(Graph_BMI, './Example')

• Network Analysis

from BMINet.Interaction import NetworkMetrics
metrics_calculator = NetworkMetrics(Graph_BMI)
metrics = metrics_calculator.compute_metrics()
