Below is a simplified Python example demonstrating the use of different classification algorithms on the Iris dataset. This example provides practical insights into algorithm behavior and performance, aiding in building intuition.

```
```python
from sklearn import datasets
from sklearn.model_selection import train_test_split
from sklearn.preprocessing import StandardScaler
from sklearn.metrics import accuracy_score
from sklearn.linear_model import LogisticRegression
from sklearn.ensemble import RandomForestClassifier
from sklearn.svm import SVC
# Load dataset
iris = datasets.load_iris()
X = iris.data
y = iris.target
# Split dataset
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.3, random_state=42)
# Standardize features
scaler = StandardScaler()
X_train = scaler.fit_transform(X_train)
X_test = scaler.transform(X_test)
# Define and train models
models = {
'Logistic Regression': LogisticRegression(),
'Random Forest': RandomForestClassifier(),
'Support Vector Machine': SVC()
}
for name, model in models.items():
model.fit(X_train, y_train)
y_pred = model.predict(X_test)
accuracy = accuracy_score(y_test, y_pred)
print(f'{name} Accuracy: {accuracy:.2f}')
```
```
