Python Top Libraries You Need to Create ML Model

By
Creating a Model of Machine Learning in Python, you need two libraries. One is 'NUMPY' and the other one is 'PANDA'.


For this project, we are using Python Libraries to Create a Model.
What Are Key Libraries You Need I have explained in the below steps. You need Two.
NUMPY - It has the capabilities of CalculationsPANDA - It has the capabilities of Data processing. To Build a model of Machine learning you need the right kind of data. So, to use data for your project, the Data should be refined. Else, it will not give accurate results. Data AnalysisData Pre-processing How to Import Libraries in Pythonimportnumpy as np # linear algebra
importpandas as pd # data processing, CSV file I/O (e.g. pd.read_csv)

How to Check NUMPY/Pandas installed After '.' you need to give double underscore on both the sides of version. 
How Many Types of Data You Need You need two types of data. One is data to build a model and the other one is data you need to test the model. Data to build…

Smart contracts blockchain tutorial automate user requests

The smart contract in Blockchain is a kind of software application that works without human intervention based on the transaction logs and provide a solution to the user request. I want to share the back end mechanism in Smart Contract of Blockchain.

Smart Contract Mechanism

What is Smart Contract

  • A smart contract is a protocol which can auto execute, facilitate, verify or enforce the negotiation of a contract.
  • Agreement between two parties you can say as a contract.
  • Incorporating the rules of physical contract into computing world, you can say as smart contract
  • Blockchain supports you to create smart contracts.
  • Smart Contracts are self-executing programs which run on the blockchain and are capable of enforcing rules
  • Using Blockchain as platform and making an agreement or contract between more than two parties, you can say as Smart Contract.

4 Top Benefits of Smart Contract

  1. Currently smart contracts are being used only in Crypto Currencies
  2. Now Smart Contracts being used in all financial transactions
  3. Smart contract can then raise funds for the foundation to complete a certain objective
  4. Primary benefit is to avoid middle men and to avoid fraud and cheating in the business world

Smart Contract Based Markets

When Smart Contract Initiated

  • Smart contracts are self executed programs. So they run automatically whenever they need. 
  • Each Smart contract in Blockchain stored in a Block.
  • Smart contracts have the following capabilities-self-execute, self-verify, self-enforce and self-constrain the agreement between two parties.

How many smart contract are present in Blockchain

  1. You can create 'N' number of smart contracts in Blockchain
  2. Smart Contract Manger over see all the transactions created in a network such that it avoids any fraud or cheating.

Summary

The contracts created under blockchain platform you can say as smart contract. The legality of contract monitored by computers but not by human beings. They enforce rules and creates alerts when something went wrong.

I am practicing Hyperledger. This is one of the top listed blockchains. This architecture follows R3 Corda specifications. Sharing the interview questions with you that I have prepared for my interview.

Though Ethereum leads in the real-time applications. The latest Hyperledger version is now ready for production applications. It has now become stable for production applications.
The Hyperledger now backed by IBM. But, it is still an open source. These interview questions help you to read quickly. The below set of interview questions help you like a tutorial on Hyperledger fabric. Hyperledger Fabric Interview Questions1). What are Nodes?
In Hyperledger the communication entities are called Nodes.

2). What are the three different types of Nodes?
- Client Node
- Peer Node
- Order Node
The Client node initiates transactions. The peer node commits the transaction. The order node guarantees the delivery.

3). What is Channel?
A channel in Hyperledger is the subnet of the main blockchain. You c…
