What is your experience with machine learning technologies and methods?

Experience with machine learning technologies and methods typically involves using Python libraries such as scikit-learn, TensorFlow, or PyTorch. For example, you can implement a classification task using scikit-learn:

from sklearn.datasets import load_iris
from sklearn.model_selection import train_test_split
from sklearn.ensemble import RandomForestClassifier
from sklearn.metrics import accuracy_score

# Load data
iris = load_iris()
X_train, X_test, y_train, y_test = train_test_split(iris.data, iris.target, test_size=0.3)

# Train model
model = RandomForestClassifier()
model.fit(X_train, y_train)

# Make predictions and evaluate
predictions = model.predict(X_test)
print(f"Accuracy: {accuracy_score(y_test, predictions):.2f}")

Experience may also include data preparation, feature selection, hyperparameter tuning, and model evaluation. It is important to understand basic algorithms (regression, classification, clustering) and be able to apply them in practice.
