## Lab #8: Ensemble Learning
### Objectives:
* Learn about ensemble learning.
* Learn about bagging.
* Learn about boosting.
### Bagging:
#### Voting Classifier:
We can create an ensemble classifier by combining predictions from multiple machine learning models.
python
knn_clf = KNeighborsClassifier(n_neighbors=5)
knn_clf.fit(X_train,y_train)
dtree_clf = DecisionTreeClassifier()
dtree_clf.fit(X_train,y_train)
svc_clf=SVC(gamma='auto')
svc_clf.fit(X_train,y_train)
knn_pred=knn_clf.predict(X_test)
dtree_pred=dtree_clf.predict(X_test)
svc_pred=svc_clf.predict(X_test)
knn_acc=accuracy_score(y_test,knn_pred)*100
dtree_acc=accuracy_score(y_test,knn_pred)*100
svc_acc=accuracy_score(y_test,knn_pred)*100
print("KNN Accuracy:",knn_acc,"%")
print("Decision Tree Accuracy:",dtree_acc,"%")
print("SVM Accuracy:",svc_acc,"%")
#### Bagging Classifier:
We can use bagging ensemble technique by creating multiple subsets of original training set with replacement.
python
bagging_clf=BAGGING_CLASSIFIER()
bagging_clf.fit(train_data_set , train_labels)
predictions=bagging_clf.predict(test_data_set)
accuracy=(np.trace(confusion_matrix(test_labels,predictions))/np.sum(confusion_matrix(test_labels,predictions)))*100
### Boosting:
Boosting ensemble technique involves building multiple models sequentially.
python
boosting_classifier=BAGGING_CLASSIFIER()
boosting_classifier.fit(train_data_set , train_labels)
predictions=boosting_classifier.predict(test_data_set)
accuracy=(np.trace(confusion_matrix(test_labels,predictions))/np.sum(confusion_matrix(test_labels,predictions)))*100

## Objectives:
* Learn about decision trees.
* Learn how decision trees work.
* Learn how decision trees can be used for classification tasks.
## Decision Trees:
Decision trees are non-parametric supervised learning methods used for classification tasks.
### How Decision Trees Work:
To build decision trees we use concepts from information theory such as entropy & information gain.
**Entropy:** Entropy represents impurity within our sample space or dataset.
$$H(S)=-sum_{i}^{n} p_i log_2 p_i$$
where $H(S)$ is entropy & $p_i$ is proportion of samples belonging to class i.
**Information Gain:** Information gain represents how much information about our sample space is gained after splitting dataset based on an attribute.
$$IG(S,A)=H(S)-
