Hands-On Projects

Implementing basic ML algorithms in Python

Implementing basic machine learning algorithms in Python is a great way to gain hands-on experience and deepen your understanding of how these algorithms work. Below, I’ll provide examples of implementing two simple ML algorithms: linear regression and k-nearest neighbors (KNN) classification.

Linear Regression

python
import numpy as np
import matplotlib.pyplot as plt

# Generate some sample data
np.random.seed(0)
X = 2 * np.random.rand(100, 1)
y = 4 + 3 * X + np.random.randn(100, 1)

# Plot the data
plt.scatter(X, y)
plt.xlabel('X')
plt.ylabel('y')
plt.title('Linear Regression Sample Data')
plt.show()

# Implement linear regression using the normal equation
X_b = np.c_[np.ones((100, 1)), X] # Add bias term
theta_best = np.linalg.inv(X_b.T.dot(X_b)).dot(X_b.T).dot(y)

# Make predictions
X_new = np.array([[0], [2]])
X_new_b = np.c_[np.ones((2, 1)), X_new] # Add bias term
y_predict = X_new_b.dot(theta_best)

# Plot the regression line
plt.plot(X_new, y_predict, 'r-')
plt.scatter(X, y)
plt.xlabel('X')
plt.ylabel('y')
plt.title('Linear Regression')
plt.show()

K-Nearest Neighbors (KNN) Classification

python
from sklearn.datasets import load_iris
from sklearn.model_selection import train_test_split
from sklearn.preprocessing import StandardScaler
from sklearn.neighbors import KNeighborsClassifier
from sklearn.metrics import accuracy_score

# Load the Iris dataset
iris = load_iris()
X = iris.data
y = iris.target

# Split the dataset into training and testing sets
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)

# Standardize the features
scaler = StandardScaler()
X_train_scaled = scaler.fit_transform(X_train)
X_test_scaled = scaler.transform(X_test)

# Train a KNN classifier
knn = KNeighborsClassifier(n_neighbors=3)
knn.fit(X_train_scaled, y_train)

# Make predictions
y_pred = knn.predict(X_test_scaled)

# Calculate accuracy
accuracy = accuracy_score(y_test, y_pred)
print("Accuracy:", accuracy)

These examples demonstrate how to implement linear regression and k-nearest neighbors classification using Python and popular libraries such as NumPy, Matplotlib, and scikit-learn. Experimenting with these algorithms and datasets will help you gain practical experience in machine learning.

Building a simple neural network using TensorFlow or PyTorch

Here’s an example of how to build a simple neural network for binary classification using TensorFlow:

python
import tensorflow as tf
from tensorflow.keras.models import Sequential
from tensorflow.keras.layers import Dense

# Generate some sample data
import numpy as np
np.random.seed(0)
X = np.random.rand(100, 2)
y = np.random.randint(0, 2, (100,))

# Build the model
model = Sequential([
Dense(4, input_shape=(2,), activation='relu'),
Dense(1, activation='sigmoid')
])

# Compile the model
model.compile(optimizer='adam', loss='binary_crossentropy', metrics=['accuracy'])

# Train the model
model.fit(X, y, epochs=50, batch_size=4)

# Make predictions
predictions = model.predict(X)

And here’s an example using PyTorch:

python
import torch
import torch.nn as nn
import torch.optim as optim

# Convert NumPy arrays to PyTorch tensors
X_tensor = torch.tensor(X, dtype=torch.float32)
y_tensor = torch.tensor(y, dtype=torch.float32).view(-1, 1) # Reshape y to match output shape

# Build the model
class SimpleNN(nn.Module):
def __init__(self):
super(SimpleNN, self).__init__()
self.fc1 = nn.Linear(2, 4)
self.relu = nn.ReLU()
self.fc2 = nn.Linear(4, 1)
self.sigmoid = nn.Sigmoid()

def forward(self, x):
x = self.fc1(x)
x = self.relu(x)
x = self.fc2(x)
x = self.sigmoid(x)
return x

model = SimpleNN()

# Define loss function and optimizer
criterion = nn.BCELoss()
optimizer = optim.Adam(model.parameters(), lr=0.01)

# Train the model
num_epochs = 50
for epoch in range(num_epochs):
optimizer.zero_grad()
outputs = model(X_tensor)
loss = criterion(outputs, y_tensor)
loss.backward()
optimizer.step()

# Make predictions
with torch.no_grad():
predictions = model(X_tensor).numpy().flatten()

Both examples create a simple neural network with one hidden layer and train it on some sample data. The TensorFlow example uses the Keras API, while the PyTorch example defines a custom neural network class.

from sklearn.model_selection import train_test_split
import numpy as np

# Assuming X_train, X_test, y_train, y_test are preprocessed datasets

vocab_size = 10000 # Assuming the vocabulary size
max_length = 200 # Maximum length of input sequences

X_train_pad = pad_sequences(X_train, maxlen=max_length)
X_test_pad = pad_sequences(X_test, maxlen=max_length)

model = Sequential([
Embedding(vocab_size, 128, input_length=max_length),
LSTM(128),
Dense(1, activation='sigmoid')
])

model.compile(optimizer='adam', loss='binary_crossentropy', metrics=['accuracy'])
