Welcome to the exciting journey of computer vision, where you can harness the power of deep learning to solve fascinating challenges! In this article, we will walk you through participating in Fatima’s Fellowship Challenge. We’ll focus on how to set up your model, training parameters, and a few troubleshooting tips to ensure you succeed!

Setting Up Your Environment

Before diving into the coding aspect, ensure you have the right environment set up. You will need:

• Python installed (preferably Python 3.6 or higher)
• A deep learning framework such as TensorFlow or PyTorch
• Access to the CIFAR10 dataset

Understanding the Model Configuration

We will be using the ResNet-50 architecture, which is known for its ability to handle image classification tasks efficiently. Below are the key configurations for the challenge:

• Epochs: 30
• Batch Size: 32
• Learning Rate: 0.0005
• Optimizer: Adam
• Dataset: CIFAR-10

Think of the epochs as the number of laps in a race. Each lap allows your model to learn and refine its approach to classification. With a batch size of 32, it’s like handing a team of 32 runners a clipboard; they can all learn and contribute at once. The learning rate of 0.0005 is the speed at which they learn—stellar enough to grasp the concepts but gentle enough to avoid mistakes. The Adam optimizer is your coach, adjusting strategies as needed, ensuring you improve effectively.

Training Your Model

Here’s how you can initiate training with the specified configurations:

import torchvision.transforms as transforms
import torchvision.datasets as datasets
import torch
import torch.nn as nn
import torch.optim as optim
from torchvision.models import resnet50

# Data preprocessing
transform = transforms.Compose([
    transforms.ToTensor(),
    transforms.Normalize((0.5, 0.5, 0.5), (0.5, 0.5, 0.5)),
])

# Load CIFAR-10 dataset
trainset = datasets.CIFAR10(root='./data', train=True, download=True, transform=transform)
trainloader = torch.utils.data.DataLoader(trainset, batch_size=32, shuffle=True)

# Initialize the model
model = resnet50(num_classes=10)
criterion = nn.CrossEntropyLoss()
optimizer = optim.Adam(model.parameters(), lr=0.0005)

# Training loop
for epoch in range(30):
    for inputs, labels in trainloader:
        optimizer.zero_grad()
        outputs = model(inputs)
        loss = criterion(outputs, labels)
        loss.backward()
        optimizer.step()

In this code, we start by importing necessary libraries and defining our model using ResNet-50. We download and preprocess the CIFAR-10 dataset, then we set up the training loop where the model learns over 30 epochs.

Troubleshooting Common Issues

• Model Not Converging: Check if the learning rate is too high; a smaller value may help.
• Out of Memory Errors: Reduce your batch size or consider using a GPU with larger memory capacity.
• Loss Not Decreasing: Ensure your data is correctly normalized and that the model is not overfitting.
