Making a simple neural network with a single hidden layer and four neurons in hidden layer. Schema of our Neural Network Import necessary libraries Inputs and outputs Converting basic python array to PyTorch tensors Code to use GPU if available Putting our variable to GPU Defining neural network instantiate neural network Weights of different layers Loss function Only one forward […]
This blog post contains following topics related to tensors: Import Version Declarations item() Zero, identity and linspace Random generator Datatypes Operation with constant Element wise operations Matrix multiplication Matrix inversion Transpose of matrix Determinant of matrix Indexing and slicing Broadcasting Reshape Squeeze and unsqueeze Concatenate and stack Reorganize the data element numpy and pytorch tensor Operations on complex numbers Import […]
Here we present a 2 in one network. A neural network which does regression and classification at same time. Iris data set has been used in this example Loading the dataset Shuffle the dataframe Inputs and Outputs We take sepal.length, sepal.width and petal.length as an input parameter. We take petal.width as first output parameter and variety as second parameter. The […]
We have three classes of images : 7, 8 and 9. The following codes uses VGG16 and CNN to build a model which classifies the images of 7, 8 and 9. Import necessary libraries as usual Load Data: Source of data 7_8_9 Class to load data and make targets Load data and display Vgg16 model Summary of model Function to […]
Importing Libraries Loading Data Make Class to load data for model Load data and display image Output VGG16 Model Summarize Function to train model Function to calculate Accuracy and validation loss Defining batch and function that load files batch-wise Get model and get data Train model for 5 epochs Plotting accuracy and loss Save model Confusion Matrix Open a new […]
We are trying to build a model using CNN with the help of PyTorch library that can differentiate between images of Ants and Bees. Data used in this task is available at : https://www.kaggle.com/watanabe2362/hymenoptera This process is divided into two parts: Part I : Building the model and saving it. Part II: Loading the model and using it. Part I: […]
