Best Machine Learning Book for Beginners

You need a mixof different technologies for Data Science projects. Instead of learning many skills, just learn a few. The four main steps of any project are extracting the data, model development, artificial intelligence, and presentation. Attending interviews with many skills is not so easy. So keep the skills short.
A person with many skills can't perform all the work. You had better learn a few skills like Python, MATLAB, Tableau, and RDBMS. So that you can get a job quickly in the data-science project.
Out of Data Science skills, Machine learning is a new concept. Why because you can learn Python, like any other language. Tableau also the same. Here is the area that needs your 60% effort is Machine learning.  Machine Learning best book to start.

Blockchain technology is new. Understanding the principles behind this technology makes you helpful to apply in your projects. 

Initially, the purpose Blockchain developed was to carry mining. In general, mining means search and find the value. Usually, minings are two types. Those are data mining and bitcoin mining.

3 Types of Blockchains

1: Private blockchains

  • Private blockchains are great for developers because they allow them to test ideas without using cryptocurrency. The developers’ ideas can remain a secret as well, because the data has not been published publicly.
  • Large institutions can capitalize on the security and permanence of blockchain technology without their transactions being public the way they are in traditional blockchains.

    2: Public Blockchains

    • Public blockchains are available to general public. An example is buying an art piece from a vendor located in another country.

    3: Hybrid Blockchains

    • These are combination of public and private.

    10 Key Glossary of Blockchain

    1. Blockchain - only blocks involved. The data which was finalized stored in blocks.
    2. Bitcoin Ledger = Blockchain
    3. Bitcoin Ledger - It is a public ledger
    4. Ledger or Blockchain - The chain of blocks
    5. Functions of Blockchain - It validates each transaction, Keeps track and verifies ownership
    6. Double Spending- It prevents duplicating the Crypto currency for using next time.
    7. Consensus mechanism - It is also called PoW (proof of work). This mechanism avoids double spending
    8. Group of Transactions - When a new group of transactions created, those will be added to the blockchain.
    9. Hash - Group of transactions created a Hash. This hash will be stored along with group of transactions in the Blockchain. Hashing is the top security mechanism in blockchain.
    10. Mining - It doesn't create Bitcoins, and alter or modify blockchain. The miners will be rewarded with Bitcoins
