Code Sample:

python
import tensorflow as tf

# Enable Eager Execution
tf.config.experimental_run_functions_eagerly(True)

# Perform a simple addition
x = tf.constant([1, 2, 3])
y = tf.constant([4, 5, 6])
result = x + y
print(result)

2. TensorFlow Extended (TFX): TFX provides a platform for deploying production machine learning pipelines, enabling seamless integration from research to deployment.

3. TensorFlow Lite: This framework allows developers to deploy machine learning models on mobile and IoT devices, making AI applications more accessible.

2. PyTorch: Flexibility and Intuitive Interface

2.1 Embracing PyTorch

PyTorch, an open-source AI framework, has gained significant traction due to its dynamic computation graph, making it a favorite among researchers and academics. Developed by Facebook’s AI Research lab (FAIR), PyTorch has a flexible and intuitive interface, making it easy for developers to experiment and iterate quickly.

2.2 Key Features of PyTorch

PyTorch is loaded with features that appeal to machine learning enthusiasts:

1. Dynamic Computational Graph: PyTorch’s dynamic computational graph allows developers to define models and make changes on-the-fly, providing more flexibility and ease in debugging.

Code Sample:

python
import torch

# Enable Autograd
x = torch.tensor([2.0], requires_grad=True)
y = 3 * x + 2
y.backward()
print(x.grad)  # Output: tensor([3.])

2. TorchScript: PyTorch allows developers to convert their Python code into a more efficient TorchScript representation, optimizing model execution.

3. Rich Ecosystem: With libraries like TorchVision for computer vision tasks and TorchText for natural language processing, PyTorch offers a rich ecosystem for various AI applications.

3. scikit-learn: Your Go-To for Classical ML

3.1 Mastering scikit-learn

While TensorFlow and PyTorch focus on deep learning, scikit-learn is designed for traditional machine learning tasks. It is a versatile and easy-to-use AI framework, built on top of NumPy, SciPy, and Matplotlib.

3.1.1 Key Features of scikit-learn

scikit-learn offers an array of features that cater to classical machine learning:

1. Comprehensive Algorithms: The library provides a wide range of algorithms for classification, regression, clustering, dimensionality reduction, and more.

Code Sample:

python
from sklearn.linear_model import LogisticRegression
from sklearn.datasets import load_iris
from sklearn.model_selection import train_test_split
from sklearn.metrics import accuracy_score

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

# Split the data 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)

# Create a Logistic Regression model
model = LogisticRegression()

# Fit the model on the training data
model.fit(X_train, y_train)

# Make predictions on the test set
predictions = model.predict(X_test)

# Calculate accuracy
accuracy = accuracy_score(y_test, predictions)
print(f"Accuracy: {accuracy}")

2. Data Preprocessing: scikit-learn offers a wide range of tools for data preprocessing, including feature scaling, encoding categorical variables, and handling missing values.

3. Model Selection and Evaluation: The framework provides utilities for evaluating model performance and selecting hyperparameters using techniques like cross-validation.
