Image Classification Using PyTorch and Convolutional Neural Network
Image classification is a popular problem in computer vision and has a wide range of applications, from facial recognition to autonomous vehicles. In this article, we will explore how to use PyTorch and a Convolutional Neural Network (CNN) to classify images.
What is PyTorch?
PyTorch is an open-source machine learning library for Python, developed by Facebook’s AI Research lab. It provides a flexible and easy-to-use platform for building deep learning models and is widely used in research and industry.
What is a Convolutional Neural Network (CNN)?
A Convolutional Neural Network is a type of deep learning model that is especially suited for image recognition tasks. CNNs are made up of layers of neurons that process different regions of the input image and are able to automatically learn features from the data.
Building an Image Classifier with PyTorch and CNN
Let’s start by building a simple image classifier using PyTorch and a CNN. First, we’ll need to import the necessary libraries:
<script type="text/javascript" src="https://code.jquery.com/jquery-3.6.0.min.js"></script> <script type="module" src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs/dist/tf.js"></script> <script type="text/javascript" src="https://cdn.jsdelivr.net/npm/@tensorflow-models/mobilenet/dist/mobilenet.js"></script> <script type="text/javascript" src="https://cdn.jsdelivr.net/npm/@tensorflow-models/knn-classifier/dist/knn-classifier.js"></script>
Next, we’ll need to load our dataset of images and preprocess them for training. This can be done using PyTorch’s `Dataset` and `DataLoader` classes. Once our data is prepared, we can define our CNN model and train it using PyTorch’s built-in optimization algorithms.
Testing the Image Classifier
Once our model is trained, we can test it on new images to see how well it performs. PyTorch makes it easy to evaluate the accuracy of our model and visualize its predictions.
Conclusion
Image classification is an important problem in computer vision and can be tackled effectively using PyTorch and Convolutional Neural Networks. In this article, we’ve only scratched the surface of what is possible with these tools, but hopefully, it has given you a good starting point for exploring image classification further.
Great video, thanks
Please share the dataset used in this video
Hi Arohi! Thanks for sharing the knowledge:) I have a qns to clarify but I'm not sure whether would you be able to see my comments. How will the the code understand or how was the datasets being seperated into inputs and labels while running the training loop as shown in your video?
Hello Aarohi
Your channel is very knowledgeable & helpful for all Artificial Intelligence/ Data Scientist Professionals. Stay blessed & keep sharing such a good content. Your channel really needs more likes & share so to reach maximum AI professionals who can encash from it
where i can find that dataset?, i just found of CNN in his github 🙁
I have a quick question regarding this video, Aarohi. I watched your video and cloned your GitHub repository to train a dataset of approximately 100 bank cheque images. However, I encountered an issue with the model's performance. When I tested it with non-cheque images, it incorrectly classified them as cheques. On the other hand, it also misclassified bank cheque images as something other than cheques. Can you help me understand and address this problem?
Thank you, I sent you a mail you didn't answer me,I need your advice please 🙏 , thank you
Yea
Thank you!
