Today, it is an era of a tight handshake between business, IT, and yet another class called Data Scientists. Here, we are citing there vital reasons why companies should compulsorily consider leveraging big data. Competitive advantage: The most important resource with any organization today is their data. What they do with it will determine their fate in the market. Decision Making: It has shifted from the hands of the elite few to the empowered many. Good decisions play a significant role in furthering customer engagement, reducing operating margins in retail, cutting and other expenditures in the health sector. Value of data: The value of data continues to see a steep rise. As an all-important resource, it is time to look at newer architecture, tools, and practices to leverage this.

 Binning Method Binning is a technique for smoothing data or dealing with noisy data. The data is sorted first, and then the sorted values are dispersed into a number of buckets or bins in this approach. Binning methods provide local smoothing since they consult the vicinity of values.  Smoothing can be accomplished in three ways: Bin smoothing entails:  Each value in a bin is replaced by the bin's mean value when smoothing by bin means is used.  Smoothing by bin median:  Each bin value is replaced by its bin median value in this method.  Smoothing by bin borders:  In smoothing by bin boundaries, the bin boundaries are determined as the minimum and maximum values in a given bin. The nearest boundary value is then used to replace each bin value. Example: Sorted data for price (in dollars): 4, 8, 9, 15, 21, 21, 24, 25, 26, 28, 29, 34 Smoothing by bin means:       - Bin 1: 9, 9, 9, 9       - Bin 2: 23, 23, 23, 23       - Bin 3: 29, 29, 29, 29 Smoothing by bin boundaries:       - Bin 1

  Installing Hadoop 3.2.1 on Windows 1.Prerequisites First, we need to make sure that the following prerequisites are installed: Java 8 runtime environment (JRE): Hadoop 3 requires a Java 8 installation. I prefer using the offline installer. Java 8 development Kit (JDK) To unzip downloaded Hadoop binaries, we should install 7zip   I will create a folder on my local machine to store downloaded Hadoop files "Drive_Name:\Hadoop_evn" 2. Download Hadoop Barriers The first step is to download Hadoop binaries from the official website . The binary package size is about 342 MB. or  Better to download Hadoop Binaries from the nonofficial . you can directly utilize these file.  After finishing the file download, we should unpack the package using 7zip int two steps. First, we should extract the hadoop-3.2.1.tar.gz library, and then, we should unpack the extracted tar file 3. Setting up environmental Variables After installing Hadoop and its prerequisites, we should configure the envi

Step by Step Process of Parrot OS Installation What is Parrot OS Parrot is a free and open-source Linux system based on Debian that is popular among security researchers, security experts, developers, and privacy-conscious users. It comes with cyber security and digital forensics arsenal that is totally portable. It also includes everything you'll need to make your own apps and protect your online privacy. Parrot is offered in Home and Security Editions, as well as a virtual machine and a Docker image, featuring the KDE and Mate desktop environments. Features of Parrot OS The following are some of the features of Parrot OS that set it apart from other Debian distributions: Tor, Tor chat, I2P, Anonsurf, and Zulu Crypt, which are popular among developers, security researchers, and privacy-conscious individuals, are included as pre-installed development, forensics, and anonymity applications. It has a separate "Forensics Mode" that does not mount any of the system's hard
