How can Tensorflow be used to visualize the augmented data from the dataset?
The augmented data can be visualized using Tensorflow and Python with the help of ‘matplotlib’ library. The images are iterated over, and plotted using ‘imshow’ method.Read More: What is TensorFlow and how Keras work with TensorFlow to create Neural Networks?We will use the Keras Sequential API, which is helpful in building a sequential model that is used to work with a plain stack of layers, where every layer has exactly one input tensor and one output tensor.A neural network that contains at least one layer is known as a convolutional layer. We can use the Convolutional Neural Network to build ...
Read MoreHow can a Convolutional Neural Network be used to build learning model?
A neural network that contains at least one layer is known as a convolutional layer. A convolutional neural network would generally consist of some combination of the below mentioned layers:Convolutional layersPooling layersDense layersConvolutional Neural Networks have been used to produce great results for a specific kind of problems, such as image recognition. It is a Deep Learning algorithm that takes an image as input, assigns importance to it, i.e. the algorithm learns to assign weights and biases to values. This helps differentiate one object from the other.The amount of pre-processing required in a ConvNet is lesser than other classification algorithms. ...
Read MoreExplain BLOB object and tree object in Git.
Git uses a series of BLOBs and trees to store content of the working directory of a project. Whenever we perform a commit operation, Git internally creates a series of trees and BLOBs, which is the binary representation of the project folder structure at that point in time of commit.What is BLOB?BLOB stands for Binary Large Object. Each version of a file in Git is represented as a BLOB. A BLOB holds a file’s data but doesn’t contain any metadata about the file or even its name.To understand a BLOB let us see an example.Create 3 files “file1.txt”, “file2.txt” and ...
Read MoreWhat is the short status in Git?
The git status command returns the current state of the −Working areaStaging areaThis command returns tracked and untracked files and changes made to the repository. However, this command does not show any commit records or information. This command usually returns a status message denoting one of the following states −No commit historyUntracked filesChanges pending to be committedClean working treeModified filesDeleted filesThe syntax for using the git status command is given below −$ git statusA screenshot of the above command’s output is below. The output indicates that the file has been modified.dell@DESKTOP-N961NR5 MINGW64 /e/tut_repo (master) $ git status On branch master ...
Read MoreHow to compare two branches in Git?
Collaborators will use multiple branches in order to have clearly separated codebase. At some point in time, we may have to merge these branches in order to have the resulting work in the main branch. It is important that we compare the differences in the branches before merging to avoid any conflicts. We will see a couple of different ways to compare two branches −Listing commit differences − This method shows commits that are present in a branch but unavailable in the other branch.Listing file changes − This method compares branches and displays how exactly a certain file is different ...
Read MoreWhy is git branching fast compared to other version control systems?
Branching allows us to diverge from the main line of work and work on something else in isolation. Conceptually, we can think of a branch as a separate isolated workspace. We have a main workspace called the master.We can create a feature branch and work separately on the feature branch to add more features to the project without affecting the main line of work. If there is some error in the feature branch, we can fix it without affecting other collaborator’s work. Once everything is working properly in the feature branch, we can merge it with the main line of ...
Read MoreHow to tag a commit in git?
The git commit is a 40-digit hexadecimal SHA1 hash. Quite often we need to bookmark a as the commit hash is difficult to memorize. This is where one can use tags. Tags can be used to name a commit. In other words, tags are labels that can be used to identify a specific commit. For e.g., “v1.0, RC1.0” are some ways to name a commit.Tags can be classified as −Lightweight TagsAnnotated TagsLightweight TagsA Lightweight tag is also known as a simple tag. These tags use a name to refer to a specific commit. Lightweight tags are private to a repository. ...
Read MoreWhat is the difference between HEAD and master in git?
A branch in Git is a series of interrelated commits. When a repository is initialized in Git, a branch will be created by default. This default branch is called the master.Multiple branches can be created within a Git repository. When a developer starts working on a new feature of the project, he may create a new feature branch and work in isolation from the master branch. Once the feature is completed changes in that branch will be merged to the master branch. In other words, the master branch will be the main line of work. The master itself is a ...
Read MoreHow do you view the revision history in Git?
Let’s say you want to view all commits to the Git repository. The git log command returns all of the commits that have been made to the repository. This command lists the latest commits in chronological order, with the latest commit first.The syntax of the git log command is given below −$ git logThe following screenshot shows how to use the command to view all commits in the current repository.dell@DESKTOP-N961NR5 MINGW64 /e/tut_repo (master) $ git log commit cbc01c8399faf9063eca4ba7781d08eebbe56aaa (HEAD −> master) Author : "Kiran Date: Fri Jan 22 19:38:42 2021 +0530 file2. txt commit 8100770d7274e6bae4e252d7b3c461020b8bc5b2 Author : ...
Read MoreDifference between a Centralised Version Control System (CVCS) and a Distributed Version Control System (DVCS)
A version control system is a software that allows you to manage changes to assets (codebase, files) over a period of time. Centralised and Distributed are the two main types of version control systems. The fundamental difference between these two lies in how they −Manage the repositoriesManage the content workflowCentralised ModelCentralised version control systems follow a server-client model. The server holds a single central copy of the project along with a history of changes made to the code base over a period of time. The basic workflow to work with a centralized version control system is given below −When a ...
