Artificial Intelligence in Healthcare
Description
Artificial Intelligence is transforming healthcare by enabling machines to perform tasks that traditionally require human intelligence. AI systems can assist in diagnosing diseases, personalizing treatment plans, predicting patient outcomes, and managing administrative workflows. AI models trained on vast amounts of medical data help improve accuracy, speed, and efficiency in medical services.
Examples (Code)
Below is the sample code
# Simulated disease prediction using a simple logistic regression
from sklearn.linear_model import LogisticRegression
from sklearn.model_selection import train_test_split
from sklearn.datasets import make_classification
# Generate sample patient data
X, y = make_classification(n_samples=500, n_features=5, random_state=0)
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2)
# Train a model
model = LogisticRegression()
model.fit(X_train, y_train)
# Predict a new patient’s diagnosis
prediction = model.predict([X_test[0]])
print("Disease Prediction:", "Positive" if prediction[0] else "Negative")
Real-World Applications
