mlkit-learn
mlkit-learn is a lightweight machine learning package designed to be interactive, easy-to-understand, and educational. It implements all of the classic machine learning algorithms from regression to gradient boosting trees. With only two lines of code, users can witness popular Kaggle datasets being preprocessed and predicted in action.
Install
pip install mklearn
K-Nearest Neighbors
Demo
- download train.csv and put in the directory of your choosing.
- run the following code.
from mklearn import knn
knn.demo(5, row=1000) # k [the number of nearest neighbour], dir [default: current directory], row [default: first 5000 rows]Use
KNN Classifier
from mklearn import knn
model = knn.KNNClassifier(5)
model.fit(train_x, train_y)
size = test_x.shape[0]
predictions = []
for i in range(size):
result = classifier.predict(test_x[i])
predictions.append(result)KNN Regressor
from mklearn import knn
model = knn.KNNRegressor(5)
model.fit(train_x, train_y)
size = test_x.shape[0]
predictions = []
for i in range(size):
result = classifier.predict(test_x[i])
predictions.append(result)Multivariate Linear Regression
Demo
- download kc_house_data.csv and put in the directory of your choosing.
- run the following code.
from mklearn import mlr
mlr.demo(row=1000) # row [default: first 5000 rows]Use
from mklearn import mlr
x_train = np.asmatrix(x_train)
x_train = np.append(np.asmatrix(np.tile(1, x_train.shape[0])).transpose(), x_train, axis=1)
x_test = np.append(np.asmatrix(np.tile(1, x_test.shape[0])).transpose(), x_test, axis=1)
y_train = np.ravel(y_train)
y_test = np.ravel(y_test)
model = mlr.MLR()
model.fit(x_train, y_train)
coef = model.coef()
predictions = model.predict(x_test)
