What is Supervised Learning?<\/h2>\n<p>Supervised learning is a method for learning predictive models based on given data.<br \/>\n    Here, &#8216;supervised&#8217; refers to labeled training data.<br \/>\n    In supervised learning, relationships between input data and output labels are learned to create a model capable of making predictions on new data.<\/p>\n<h3>1.1 Types of Supervised Learning<\/h3>\n<p>Supervised learning can be broadly divided into two types: classification and regression.<\/p>\n<ul>\n<li><strong>Classification:<\/strong> Predicts whether a given input data belongs to a specific class.<br \/>\n        For example, classifying whether an email is spam or not falls into this category.<\/li>\n<li><strong>Regression:<\/strong> Predicts continuous numeric values based on input data.<br \/>\n        For instance, predicting house prices based on the area of the house is an example of regression.<\/li>\n<\/ul>\n<h2>2. Introduction to PyTorch<\/h2>\n<p>PyTorch is an open-source machine learning library developed by Facebook that provides a variety of useful features for deep learning researchers and developers.<br \/>\n    In particular, it supports dynamic computation graphs,<br \/>\n    which makes it easier to debug and modify models.<\/p>\n<h3>2.1 Installing PyTorch<\/h3>\n<p>To install PyTorch, you can use the following command.<br \/>\n    The command below shows how to install PyTorch using pip:<\/p>\n<pre><code>pip install torch torchvision torchaudio<\/code><\/pre>\n<h2>3. Creating a Deep Learning Model<\/h2>\n<p>Now, let&#8217;s create a simple deep learning model using PyTorch.<br \/>\n    This example will address a classification problem, using the famous MNIST dataset to build a model that classifies handwritten digits.<br \/>\n    The MNIST dataset consists of images of digits from 0 to 9.<\/p>\n<h3>3.1 Loading the Dataset<\/h3>\n<p>First, we will load the MNIST dataset and split it into training and testing data.<\/p>\n<pre><code>import torch\nfrom torchvision import datasets, transforms\n\n# Data transformation (normalization)\ntransform = transforms.Compose([\n    transforms.ToTensor(),\n    transforms.Normalize((0.5,), (0.5,))  # Normalized to mean 0.5, standard deviation 0.5\n])\n\n# Download and load the MNIST dataset\ntrain_dataset = datasets.MNIST(root='.\/data', train=True, download=True, transform=transform)\ntest_dataset = datasets.MNIST(root='.\/data', train=False, download=True, transform=transform)\n\ntrain_loader = torch.utils.data.DataLoader(dataset=train_dataset, batch_size=64, shuffle=True)\ntest_loader = torch.utils.data.DataLoader(dataset=test_dataset, batch_size=64, shuffle=False)<\/code><\/pre>\n<h3>3.2 Defining the Model<\/h3>\n<p>Deep learning models are defined by inheriting from nn.Module. Here, we will define a simple neural network model.<\/p>\n<pre><code>import torch.nn as nn\nimport torch.nn.functional as F\n\nclass SimpleNN(nn.Module):\n    def __init__(self):\n        super(SimpleNN, self).__init__()\n        self.fc1 = nn.Linear(28 * 28, 128)  # First layer\n        self.fc2 = nn.Linear(128, 64)       # Second layer\n        self.fc3 = nn.Linear(64, 10)        # Output layer\n\n    def forward(self, x):\n        x = x.view(-1, 28 * 28)  # Convert 2D image to 1D vector\n        x = F.relu(self.fc1(x))  # Apply ReLU activation function\n        x = F.relu(self.fc2(x))\n        x = self.fc3(x)\n        return x\n\n# Create an instance of the model\nmodel = SimpleNN()<\/code><\/pre>\n<h3>3.3 Defining the Loss Function and Optimizer<\/h3>\n<p>Now we will define the loss function and optimizer. We will use the cross-entropy loss function and the Adam optimizer.<\/p>\n<pre><code>import torch.optim as optim\n\n# Loss function\ncriterion = nn.CrossEntropyLoss()\n# Optimizer\noptimizer = optim.Adam(model.parameters(), lr=0.001)<\/code><\/pre>\n<h3>3.4 Training the Model<\/h3>\n<p>Now it&#8217;s time to train the model. For each epoch, we will pass the data through the model iteratively,<br \/>\n    compute the loss, and update the weights.<\/p>\n<pre><code>num_epochs = 5\n\nfor epoch in range(num_epochs):\n    for images, labels in train_loader:\n        # Zero the gradients\n        optimizer.zero_grad()\n        # Pass images through the model\n        outputs = model(images)\n        # Calculate loss\n        loss = criterion(outputs, labels)\n        # Backpropagation\n        loss.backward()\n        # Update weights\n        optimizer.step()\n    \n    print(f'Epoch [{epoch+1}\/{num_epochs}], Loss: {loss.item():.4f}')<\/code><\/pre>\n<h3>3.5 Evaluating the Model<\/h3>\n<p>Once training is complete, let&#8217;s evaluate the model using the test data.<\/p>\n<pre><code>correct = 0\ntotal = 0\n\nwith torch.no_grad():  # Disable gradient calculation\n    for images, labels in test_loader:\n        outputs = model(images)\n        _, predicted = torch.max(outputs.data, 1)  # Extract the index of the maximum value\n        total += labels.size(0)\n        correct += (predicted == labels).sum().item()\n\nprint(f'Accuracy of the model on the test images: {100 * correct \/ total:.2f}%')<\/code><\/pre>\n<h2>4. Conclusion<\/h2>\n<p>In this lecture, we learned how to build a basic deep learning model using PyTorch and<br \/>\n    solve a classification problem using the MNIST dataset.<br \/>\n    This approach utilizing supervised learning can be applied in various fields and can be expanded into more complex models.<\/p>\n<h3>4.1 Additional Learning Resources<\/h3>\n<p>If you want to learn more about deep learning, check out the following resources:<\/p>\n<ul>\n<li>Deep Learning by Ian Goodfellow et al.<\/li>\n<li>Official PyTorch documentation: <a href=\"https:\/\/pytorch.org\/docs\/stable\/index.html\">https:\/\/pytorch.org\/docs\/stable\/index.html<\/a><\/li>\n<li>CS231n: Convolutional Neural Networks for Visual Recognition<\/li>\n<\/ul>\n<p>Deep learning is a vast field of research that requires continuous learning.<br \/>\n    We hope this will help you on your deep learning journey!<\/p>\n<p><\/body><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Deep learning is a field of artificial intelligence (AI) that uses multilayer neural networks to learn patterns from data.
