The dataset used in this problem was created by Zalando Research. Additionally, we’ll be using a very simple deep learning architecture to achieve a pretty impressive accuracy score. In the training set, you will have a .csv file and an image folder: The .csv file in our test set is different from the one present in the training set. And not just for Deep Learning models, this will be handy for other typical ML model exercises like RF, SVM and even text mining where after creating the DTM, data size explodes. Step 2 : Import the libraries we’ll need during our model building phase. This csv file which is provided to you only contains the names of all the images and their corresponding class to which they belong. Convolution is an element-wise multiplication. Examples of different filters and their effects. This will be a foundation for you. Is Google Colab helpful here? To extract the features from the images, you have to use the actual image provided to you. Will thhis work on Windows powered computer? You can see there are 12 images and one MTL text document. The example which I have used here has images of size (28,28,1). Manually checking and classifying images is a very tedious process. Thank you for the suggestion Steve! In this challenge, we need to identify the digit in a given image. As you have 3 classes to predict, the number of neurons in the output layer will be 3 and not 4. The method of classification that you will attempt is called supervised classification. Hi Pulkit, Explore and run machine learning code with Kaggle Notebooks | Using data from multiple data sources Step 4: Supervised Classification.
