Python for Business: Optimize Pre-Processing Data for Decision-Making

Amelia — Tue, 18 Jan 2022 07:54:35 +0000

The rise of machine learning and the use of Artificial Intelligence gradually increases the requirement of data processing. That’s because the machine learning projects go through and process a lot of data, and that data should come in the specified format to make it easier for the AI to catch and process.

Likewise, Python is a popular name in the data preprocessing world because of its ability to process the functionalities in different ways. Besides, libraries like Pandas and Numpy make Python one of the most efficient technologies available in the market.

In this article, we will discuss how Python runs data preprocessing with its exhaustive machine learning libraries and influences business decision-making.

Data Preprocessing is a Requirement

Data preprocessing is converting raw data to clean data to make it accessible for future use. Elaborately, the steps and methods to organize and reshape the data to execute it suitably for use or mining, the entire process, in short, known as Data Preprocessing.

With technological advancement, information has become one of the most valuable elements in this modern era of science. However, data comes in different sizes and formats (text, images, audio, video, etc.). Hence, it’s mandatory to preprocess the data to provide it in the final use.

Accordingly, before using that data in machine learning or an algorithm, you need to convert it into a precise format suitable for the system to inherit it. For instance, the Random Forest Algorithm in Python doesn’t support null values. Hence, it would help if you preprocessed the null values before using the data in the Random Forest algorithm.

Therefore, if you don’t preprocess the data before applying it in the machine learning or AI algorithms, you are most likely to get wrong, delayed, or no results at all. Hence, data preprocessing is essential and required.

Python as a Data Processing Technology

Comprehensive data processing requires robust data analysis, statistics, and machine learning. As a high-level, open-source programming language, Python possesses a firm grip over these functionalities. Consequently, Python has become one of the most efficient instruments for data preprocessing.

Here are some of the factors that make Python second to none as in data preprocessing:

Comprehensive Libraries: Python has many libraries like NumPy, suitable for machine learning, and supports high-level mathematical functions, making it great with algorithms. Besides, libraries like Cython and Numba allow users to create complex functions to compile dynamic codes running process calculations faster. Hence, rather than not shuffling around, you can utilize Python libraries and remain firm.

Open Source: Python has an OSI-approved open source license. It’s completely free to use and distribute for both private and commercial use. Hence, as a high-level free language, it makes Python second to none.

Built-in Data Analytics Tools: Python has some built-in data analysis tools that make the job easier for you. For example, the Impute library package handles the imputation of missing values, MinMaxScaler scales datasets, or uses Autumunge to prepare table data for machine learning algorithms.

Flexibility: Python offers enhanced productivity and reduced code, reduced time to code, and debug time. Besides, it offers data model creation, systematized data sets, developable web services, ML-powered algorithms, versatile use of data mining and so many other very efficient functionalities that make it very flexible and productive to use for Data Preprocessing.

Compliance: Python offers enhanced productivity and reduced code, reduced time to code, and debug time. Besides, Python allows creating data models, systematizing data sets, and developing web services for proficient data processing.

Also, you can use ML-powered algorithms, utilize versatile data mining, and many other very efficient functionalities that make it very flexible and productive to use for Data Preprocessing.

Natural Language: Python is so powerful that you can use it for high-level and soft programming purposes. Therefore, using Python makes you work less and reduces the effort of learning other technologies.

In addition, handling data preprocessing or utilizing them in machine learning are fundamental skills for professionals in the field. Therefore, you can learn about Data Preprocessing Methods in Python for future use.

Why Choosing Python Over Other Technologies in FinTech?

The magnificent development drive of Python holds a vital position in the FinTech industry because of its robustness, exquisite data analysis, and data modeling ability. Hence, Python has been the uttermost choice for financial analysts, traders, and Algo traders.

There are some aspects where Python is largely used and let’s discuss them.

Banking & Digital Payment Solutions

Banking and digital financial transactions require high-end security to stop breaching and safety of the transactions. Python offers stability and security in a financial transaction. Moreover, Python offers secure APIs, scalability, digital management payment gateway integrations making the digital payment solutions safe and more manageable. For example, Citigroup, Goldman Sachs, PayPal, Stripe & GooglePay use Python.

Algorithmic Trading

Python is arguably the best and most famous technology at this moment to use in the algorithmic trading world. Because of the Python libraries like Panda, trading analyses like, volatility calculation, moving windows, etc can be sorted out in minutes. Besides, you can integrate Python directly with trading platforms like MetaTrader 5 and securely run your algorithmic trading business and gain profit. Learn to connect Python directly in the MQL5 Community.

Cryptocurrency

Both the individuals and companies that are into cryptocurrency need essential analytics that would help them to take the right decision about the market. Developers can make systems busting Python Cryptocurrency libraries that visualize best pricing schemes analyzing the market. The global market is slowly flowing towards Crypto and soon enough there will be more Python apps in Cryptocurrency.

Advantages and Disadvantages of Data Preprocessing in Python

Advantages

Here are some of the advantages of using Python as data preprocessing technology:

Python offers a clear and neat syntax with a short learning curve.
It Provides high-level mathematical function libraries like NumPy, Cython, Numba, SymPy, Pymc, etc.
Python’s multi-paradigm functionality sustains functional, procedural, and both Object-Oriented and Aspect-Oriented programming styles.
Enterprise Application Integration (EAI): EAI helps Python communicate or call codes directly from other languages like Java, C, or C++.
Python has large user communities on the web and different social media platforms to assist in learning.

Disadvantages

Well, every technology comes with a few drawbacks. Python makes no exception. However, considering the benefits and features Python offers, the disadvantages are minimal to mention.

Here are some of the disadvantages of using Python as data preprocessing technology:

Python’s memory consumption is high.
It is a dynamically typed language where some machine learning or data science fields prefer Statically Typed programming languages.
Python is suitable for building Algorithmic prototypes; it shorts infrastructure set up to deploy the model in the cloud.
Somewhat becomes slow in computation.

Python Makes Decision Making Simple

Business decisions require the keyword What Has Happened to understand the situation and take necessary actions. In such cases, data analysts run the descriptive analytics to find out, and Python comes into the business.

Decision-making requires proper data analysis, and Python provides the results after using its vivid functionalities like data analytics, numerical computation, scientific computation, statistical analysis, and many more. Hence the required action for business or trading becomes easier for the algorithm or the operator handling the algorithm.

The Reference Specification Type and Type Conversions in JavaScript

Amelia — Thu, 06 Feb 2020 10:45:24 +0000

Reference Specification Type

A Reference is a resolved name binding.

It is made up of 3 components:

Base Value: (Type: undefined, Object, Number, String, Boolean, Environment Record). A base value of undefined means the reference could not be resolved to a binding.
Referenced name: (Type: String) The name given to the reference.
Strict reference flag: (Type: Boolean)

Type Conversions in JavaScript

The JavaScript runtime system performs automatic type conversions as needed.

Conversion can be done to primitive types as per the following rules:

ToBoolean

This converts the argument to Boolean type.

//falsy values in JavaScript
console.log(Boolean(undefined));// false
console.log(Boolean(null));// false
console.log(Boolean(0));// false
console.log(Boolean(+0));// false
console.log(Boolean(-0));// false
console.log(Boolean(""));// false
console.log(Boolean(false));// false

//truthy values in JavaScript
console.log(Boolean(true));// true
console.log(Boolean("Hello"));// true
console.log(Boolean(4));// true
console.log(Boolean(+Infinity));// true
console.log(Boolean(-Infinity));// true
console.log(Boolean("0"));// true
console.log(Boolean({}));// true

ToNumber This converts the argument to Number type.

console.log(Number(undefined));// NaN
console.log(Number(null));// 0
console.log(Number(0));// 0
console.log(Number(+0));// 0
console.log(Number(-0));// -0
console.log(Number(""));// 0
console.log(Number(true));// 1
console.log(Number("Hello"));// NaN
console.log(Number(4));// 4
console.log(Number(+Infinity));// Infinity
console.log(Number(-Infinity));// -Infinity
console.log(Number("0"));// 0
console.log(Number({}));// NaN
ToString This converts the argument to String type

console.log(String(undefined));// undefined
console.log(String(null));// null
console.log(String(0));// 0
console.log(String(+0));// 0
console.log(String(-0));// 0
console.log(String(""));//
console.log(String(true));// true
console.log(String("Hello"));// Hello
console.log(String(4));// 4
console.log(String(+Infinity));// Infinity
console.log(String(-Infinity));// -Infinity
console.log(String("0"));// 0
console.log(String({}));// [object Object]
ToObject

This converts the argument to String type. Trying to convert undefined and null to Object type will result in TypeError exception.

An interesting thing to note about JavaScript is a numeric character within quotes gets converted to Number type in the below scenario:

var varA = "8"+"0";
console.log(varA); //80
console.log("typeof varA is " + (typeof varA));//typeof varA is string 
// this is a way of string concatenation in Javascript

var varB = +"8" + +"0"
console.log(varB);//8
console.log("typeof varB is " + (typeof varB));//typeof varB is number

varC = "88";
console.log(typeof +varC);//number

Also we have spoke about the Reference Specification Type , now it is important to note that :

Primitive types in JavaScript are always passed by value

Objects types in JavaScript are always passed by reference

Let's see examples to prove this:

var a = 20;
var b = a;
console.log(a);// 20
console.log(b);// 20
a= 90;
console.log(a);// 90
console.log(b);// 20

Here when the assignment var b = a; was done, JavaScript executed this code in the below steps:

Create a variable reference.
Add the named reference of the variable created in step 1 as b
Copy the value of variable referenced by the named reference a to the variable with named reference b

Let's see another example of primitives:

var c = 77;// 77
console.log(c);
function ChangeNum(x){
    x = 88;
}
ChangeNum(c);
console.log(c);// 77

This further proves our point. Now let us try it on Object and Object properties:

var objB = objA;
console.log(objA);//{ prop1: 'aProp' }
console.log(objB);//{ prop1: 'aProp' }
//now we will change "prop1" property of object referenced by objB and see if objA also gets changed
objB.prop1 = "bProp";
console.log(objA);//{ prop1: 'bProp' }
console.log(objB);//{ prop1: 'bProp' }

This confirms that objects get passed around by reference. Now let us assign a different object to objA. In this case will objB loose the reference to the previous object? Let's see

objA = {
    differentProp1 : "differentA"
}
console.log(objA);//{ differentProp1: 'differentA' }
console.log(objB);//{ prop1: 'bProp' }

No it does not. It is still pointing to the same memory location as it was earlier. but objA now points to a different location in the memory because the = operator changes the reference named objA to a new location in the memory.

function ChangeObjectProp(o){
    o.prop1 = "changedProp";
}
ChangeObjectProp(objB);
console.log(objB);//{ prop1: 'changedProp' }

Here the formal parameter to the function ChangeObjectProp holds the reference same as what objB holds. And because of this the original object got modified which again confirms that the object was passed by reference.

Now we have seen the Reference Specification type and how type conversions will behave in the world of JavaScript, we will move on to a core concept of Lexical Environment and Scope in our next post.

Best Java books for Beginner and Expert

Amelia — Fri, 31 Jan 2020 08:16:29 +0000

One of the main problems with learning Java is to keep pace with the increasing number of releases. For example, Java 8 was released in 2014 which completely changed how Java is written and now within the last 6 month, we have two major Java releases in the form of Java 9 and Java 10, Java 11, 12, and 13. But the good thing is that the core of Java is still the same and all its releases are backward compatible.

If you are learning Java first time, then it’s very important to choose the online course which is up-to-date, otherwise, you will be left behind in the job market and your day-to-day programming job with outdated skills.

But, before that, let me first congratulate you on making an excellent decision of learning Java, one of the most popular main-stream programming language of the world.

The support in modern Java for multiple paradigms increases the need for specific best-practices advice, and this book delivers.

As in previous editions, each chapter of Effective Java, Third Edition, consists of several “items,” each presented in the form of a short, stand-alone essay that provides specific advice, insight into Java platform subtleties, and updated code examples. The comprehensive descriptions and explanations for each item illuminate what to do, what not to do, and why.

The third edition covers language and library features added in Java 7, 8, and 9, including the functional programming constructs that were added to its object-oriented roots. Many new items have been added, including a chapter devoted to lambdas and streams.
