Predictive Analytics – Explanation in a Simple Way

Let’s say you own a company, to increase revenues and have a better market positioning for your product, what would your approach be? Would you like to predict and formulate ways through which you could acquire more clients, or would you prefer to predict which existing customers would attrite and if given a chance what could you surely do to retain them? What if you had access to the best marketing strategy accurately targeting the potential audience, or if you knew the most accurate prediction in cross-selling or upselling opportunity with your customers, what if your company could predict almost with certainty what each existing customer wants and you could device plans to address those needs. Sounds exciting?
Most businesses are customer-centric in nature, directly or indirectly, and this kind of information could be of colossal advantage for the growth and sustenance of most organisations. Currently, we have entered the most established phase of empowered customer, where to exist in the long run, most organisations are ferociously finding ways to connect with the customer. Organisations acknowledge that to sustain and grow they need have more evolved interactions with their customers, and that is easy when they have a strong knowledge base with the customers. This is Predictive Analytics for you.
Predictive analytics is viewed by most people as a branch of big data, although it is partially true, it is vast enough to be considered as a separate phenomenon.
Predictive analysis allows a more proactive approach, with a foresight on anticipating and predicting outcomes and behaviours, based upon data and not only assumptions. What’s exciting is that it not only predicts, but also suggests actions derived from the findings, and provide decision options.
Over a period of time, after cleaning the volume and variety of data,
A project is designed and Data Mining for Predictive Analytics prepares data from various sources on which Reporting Analysis is done, which gives insights on what happened and why did it happen.
The next stage is Monitoring, getting real-time understanding of what is happening now.
Predictive Analytics, where Statistical Analysis is performed in getting insights into the future, keeping in line with the hypothesis.
Predictive Modelling Deployment provides possibilities of what could happen derived from historical facts and behaviors. Taking into account an action plan is suggested to get the desired output.
Model Monitoring ensures that the models are managed and monitored to review the performance and guarantee that it provides decisions as expected.
Predictive Analytics and its application have a great scope across a variety of industries
Customer Centric Businesses apply predictive analytics to achieve objectives in Marketing campaigns, sales, and across the customer lifecycle, from acquisition to retention.
Health Care applies predictive analysis to gauge the risk factors of patients before they develop certain conditions.
Fraud Detection applies predictive analysis to predict inaccurate credit applications.
Marketing applies predictive analytics to identify the most effective combination of product versions, marketing material, communication channel and timing that can be used to identify and target a given customer.
There is a lot more to the world of predictive analytics, it is no longer in the nascent stage and is fast growing. To acquire a basic understanding of the functionalities of predictive analysis would be a very wise thing to do.

As a type of Artificial Intelligence, Machine Learning is changing and reshaping, how people are doing business. Most companies are investing in these modules, purely because of the magnitude of the impact, it has on business. Machine learning is a big deal and is already impacting our lives in ways we do not consciously know.
Machine learning, as commonly known, uses algorithms to make computers learn on their own, without having to program them clearly at every step. Now, this automated analytical model helps find hidden insights to the new data, which might not be found, if the analysis was done with a traditional approach. For this reason, machine learning is creating a lot of buzzes these days in software development. Some also predict that it will transform the development process of a web application.
Read on to learn the impact of Machine Learning on web development

Data Mining

Data mining techniques are used by enterprises to produce new information from the colossal pool of data. Web mining as a data mining technique is used by many websites to discover patterns and insights from the available data. Machine learning also like data mining detects patterns, however, machine learning has the ability to automatically program actions based on detected patterns.

Comprehend Customer Behavior

Machine learning capabilities are also applied on web applications to better understand customer behavior and to aptly engage the customer. An e-commerce website usually understands the products for specific customers based on their searches and can lead to better conversion related to a product. It can also use algorithms to better understand the features desired by the customer. Machine learning algorithms can also be used to communicate with the customer, analysing their queries and perhaps even connecting them with the customer service team, all in the name of enhancing customer experience.

Modified information

Social networking sites use this feature of personalised content for each user. Facebook most popularly uses, the machine learning algorithm to get personalised newsfeed for each user. Facebook essentially uses a combination of predictive analysis and statistical analysis to detect patterns, based on the content that the user reads and likes. Hence while developing web applications programmers can embed the same technology and deliver personalised content to users based on their choice and preferences.

Expedite Product detection

Large companies with online portals are developing machine learning algorithms to deliver smart search for individual users. These algorithms will assist the user to find the relevant products faster.

Mitigating Security Threats

A number of security firms already use machine learning technology like logistic regression which identifies mischievous websites amongst many. Similarly, some enterprises also use classification algorithms to identify phishing websites, based on criterion like domain identity, data encryption techniques etc.., this will make it easier for programmers to mitigate their web applications from evolving security threats in the future.
So overall, It is not only changing the way web applications are being developed but, the way they will be developed in the future. All these applications are aimed at and will enhance customer experience. Web programmers also have the independence of combining multiple machine learning API’s to further enrich the customer experience by offering faster and smoothers applications.

The idea of the creation of Python originated sometime in 1989, specially to overcome the shortcomings of the ABC language. Hence Python was created incorporating all the good features of the ABC language and adding new desired features, namely extensibility and extension handling. There after many versions of the language was created with newer and better upgradations to the already existing features. Python today has multiple implementations that work in the native languages they are written in like, Java, C, etc…, they also have the capability of interacting with other languages by the use of modules, and most of these modules are open source.
Python is generally used across a variety of channels, for example, like in, GUI based desktop applications, graphic design and image processing applications, games, web applications, business and enterprise applications, also language development and prototyping, so the scope is vast.
Python is always considered as different and better from other languages purely because, it is very user-friendly, especially if you are starting up, the syntax of Python is very simple and readable, it is very comprehensive. It has nice built-ins, a good availability of libraries, amongst other benefits. It is also widely used for developing many web products which are popular, like YouTube, Google, Yahoo! Map etc…,
Python is generally compared with other interpreted languages like Java, JavaScript, C++, Perl, Smalltalk.
Read on for a quick comparison of Python with these languages

Python v/s Java

Python programs runs slower than Java, but they take less time to develop. The codes in Python are at least 3.-5 times shorter than Java, while the Java codes are longer. Another plus is that Python is dynamically typed while Java is not.

Python v/s JavaScript

Python and JavaScript are almost equivalent as an ‘Object Based’ programing language. The major difference is in the fact that, Python can be used as a scripting language as well as a programing language, with the ability to write much larger programs and much better code reuse through true object-oriented programming, while JavaScript can only be used as a scripting language.

Python v/s C++

If Python codes are 3-5 times shorter than Java, with C++ they are at least 5-10 times shorter. Python is a pure OOPS programming language as opposed to C++. Python wins as a ‘Glue’ language which can be used to combine components written in C++.

Python v/v Perl

Python and Perl share the same background and to an extent also show similar features, however, the key difference is in their working philosophy. Perl supports common application-oriented tasks, like file scanning, report generating and built-in regular expression features. Python highlights support for object-oriented programming and common programming methodologies, which assist programmers to write readable and hence maintainable programming codes. Python is not overly cryptic and shows applicability which is beyond the niche capability of Perl.

Python v/s Smalltalk

Although Smalltalk is an object-oriented language, it lacks the dynamic building and dynamic binding that Python offers. Python boosts of a vast library, with more features, Smalltalk has a refined library. Python has a separate development and environment distribution of code while Smalltalk follows a monolithic code.
It is important to understand the above comparisons are based on only the language issues. While choosing a programming language there are many factors that need to be considered, like cost, availability, training, prior investment and above all the ease or emotional attachment of the programmer.
Although to sum up, clearly Python is considered popular amongst most programmers as it is easy to adapt compared to other languages, and there is an available wide-ranging collection of data science libraries.

The outburst of information on the internet is a boon for data enthusiasts. This available data is rich in variety and quantity, much like a secret box of information, waiting to be discovered and put to use. Say for example you need to take a vacation, you can scrap a few travel websites, imagine the possibilities, you can pick up travel recommendations of places to visit, popular places to eat, and read all positive feedback from previous visitors. These are a few options, but the list is endless.
How do you extract this information from the internet, is there a fixed way to get information, concrete steps to follow? Not really, there is no fixed methodology. The internet has a lot of unstructured and noisy data, to make sense of this overload of information, you need to use Web Scrapping. It is believed that almost any form of data on the internet can be scrapped, and there are different kinds of web scrapping techniques, each available to tackle different scenarios.

Why Python? as is common knowledge to all, Python is an open source programming language, hence you will find many libraries to perform one function. It does not mean that you will need to learn every library, but you will need to know how to put in a request, to communicate effectively with the website.

Here are 5 Python Web Scrapping Libraries you can use

1. Requests – It is a simple and powerful HTTP library; you can use it to access web pages. It can access API, post to forms and much more.
2. Beautiful Soup 4 (BS4)– It is a library that can use different parsers. A Parser is essentially a program that is used to extract information from XML or HTML documents. It can automatically detect encodings, which means you can manage HTML documents with special characters. It has the ability to navigate a parsed document easily, thus making it quick and easy to build a common application.
3. Lxml – It has great performance and production quality. Initially, it was believed that if you need speed then you should use lxml, and for managing messy documents you should use BeautifulSoup, however that is no longer true, it’s vice-versa now, BeautifulSoup can also support lxml parser. Therefore, it is recommended that you try both and settle on the one convenient to you.
4. Selenium – So Requests is generally used to scarp a website, however, there are some sites that us JavaScript for its content. These sites need something more powerful, Selenium is a tool which can automate browsers, and it also has Python bindings for controlling it right from your application. All this makes it ideal to integrate it with your chosen parsing library.
5. Scrapy –it can be considered as a complete web scraping framework. It can be used to manage requests, store user sessions, follow redirects and manage output pipelines. What is phenomenal is that you can reuse your crawler, scale it by swapping Python web scraping libraries, like for example, use Selenium to scrap dynamic web pages, all while managing complex data pipelines.

To recap, you can choose from, Requests and Selenium to scrap HTML and XML from web pages, and you can use BeautifulSoup and lxml to parse into meaningful data and Scrappy to manage huge requirements and if you need to, build a web crawler.

If you are at a junction, deliberating future options and fields to pursue your career, specially, if you plan to advance in the field of IT, then read on to understand some approaches that could come across as life altering for you.As the recent trends suggest, to be of relevance in the field of IT over the coming years, it is imperative that you adopt a skill that adds value to the organisation and your role, more so in the times of the Big Data boom.
Predictive analytics is one such technique that is applied within most organisations and is quickly gaining popularity due to the positive business impact it creates.
Reporting, Optimizing and Predicting are three things that you can most often do with your data. hence at the essence of it, predictive analysis is not something new or of great complication. But, ‘Do you have a method through which you can capture and analyse data from the future?’ No, however, there are ways you can predict the future by using the data from the past.

Predictive Analysis thus is an organised technology with a scientific approach, which is used to make predictions about the unknown future events. Intelligent approaches like statistical algorithms, data mining statistics, modelling, machine learning etc…, are applied to analyse past and current data, to make predictions about the future.
In fact, the need for predictive analysis emerged from the desire to turn already available raw data into getting informative insights that can be used not only to understand the past patterns, but based on these patterns, to develop a model with the ability to predict future outcomes.
Predictive analytics can be adopted by any organisation with a defined business goal, like that of reducing risks, increasing productivity, and increasing revenue.
Some examples are,
Banks and Financial Services, to measure the likelihood of fraud, measure credit risk, among others.
Retail and E-commerce, to make inventory of products, plan promotional events,
Health Insurance, besides fraud to identify patients at risk for chronic illness,
Manufacturing to reduce quality and production issues, service distribution, optimize resources,
Government Sectors for campaigning, to better understand human behavior,
these are just a few areas amongst others that benefit from the right use of predictive analysis technique.

In recent times all businesses across industries understand the significance of predictive analytics, however, after a little research it is understood that a staggering 53% business feel there is a huge gap between, ‘what needs to be done?’ and ‘what is currently done?’, due to lack of accurately skilled and trained resources, the results derived from the analysis might not give very accurate and valuable insight. And interestingly 89% businesses understand the value of PI and feel the need to have a dedicated staff to perform Predictive Analysis, giving it a status of a separate team and not an extension of BI. Hence there is a sudden spike for skilled staff in the domain of big data with appropriate predictive analysis skill set.

Our online presence is not a matter of choice anymore; we often find ourselves using online portals to shop, connect with a doctor, research, basically from going on a vacation to preparing for motherhood, marriages, and dating, to banking, and even school and college admissions, all of these are done online, we even use social networking to express ourselves, through tweets, posts etc…,
Excessive usage of the internet creates online activity logs that contain humongous amounts of data.
Now imagine the camera’s mounted almost on every corner of the street and satellite based observations like the google map and google earth, they also collect data in large numbers on how people conduct themselves.
This data that is generated is being collected in large numbers around the clock, in real time and historic, this data further needs to be extracted, however, it is easier said than done, data is huge and extraction and explanation of the same cannot be done effortlessly. Most of the data collected is unstructured and not authentic, so you need to be wise to catch the correct characteristics at the right time.
People who can perform this extraction in a functional manner and make sense of it are called, Data Scientist or Data Analysts. The competencies that help them in this task are, sound knowledge of Mathematics, Computer Science, and Statistics.
The job of a data scientist is not only extracting data and analysing it, but to clean the data in such a manner that they can also predict and forecast trends for an assigned business, based on certain hypothesis or conditions. And that is the uniqueness they get to their job, the ability to accurately pre-process data and predict and forecast, sets one data analyst apart from the other.
A career in big data has become a dream choice for most job seekers these days, there is a lot that an organisation can achieve with the right application of data science. Some companies have identified this, and are either training their internal staff on the skills required to perform the job, while others are not yet too open to hire a full time resource. Although that day is not too far when the position of a data analyst will become imperative in every organisation.
If you are planning to enter the data science industry to make a great career in big data, then you need to adapt and acquire certain competencies and expertise in data analytics related tools, in addition to the above mentioned prerequisites. For example, programming languages, like R, and Python, SAS, a working knowledge of Machine Learning, and Predictive analysis. Also a sound knowledge in the industry you plan to work for, e.g., healthcare, or IT, Education etc.., will be an added advantage.
There is a huge gap between the demand and available resources in the field of data science, hence making a career shift in this direction would be wise and also lucrative, recent researchers have suggested that a data scientist earns more than experienced engineers. Clearly, this is a field with huge potential.
Do take up certifications, that will further assist you to springboard yourself in the field of data science.

Over the past couple of years, the topic of Big Data has taken the form of quite the hot topic. This is basically because a new career has come up and it has so many more possibilities, which seemed impossible less than a decade ago. The Harvard Business School has already given the field of big data, its seal of approval by declaring it to be one of the sexiest careers of the 21^st century. With this approval, the world not only took notice but also started taking up this field of big data with much furor.
There are quite a lot of facts about the field of that many of the data aspirants still are unaware about, so for the benefit of all of those, here’s a total list of amazing and impressive facts about big data.

1. Presently the digital universe is made up of about 2.7 Zettabytes of data. One thing to note here is that the unit of Zettabyte was till data a very hypothetical concept, which was believed to never be able to be fulfilled. But today it has become quite the reality.
2. In the year of 2011, the US Library of Congress ended up collecting up to 235 terabytes of data, which if translated in terms of the unit of megabytes, means about 235, 000 megabytes of data.
3. The former President of America, Mr. Barrack Obama is said to have invested an amount of $200 million as a part of the investment of his administration in the various research projects continuing their work in Big Data.
4. There is a study that was conducted, which reported that by the year 2020, the online business transactions between businesses as well as individuals would amount to about 450 billion transactions per day.
5. The fact that Facebook has a huge number of enormous store houses which work as cold storage with huge turbines, is known to everyone. But did you know that Facebook is able to store, access and analyze more than 30+ petabytes of all the user generated data?
6. About 90% of all the Hadoop data analytics tool users usually perform a lot of analytics on huge volumes of data and data sets, which was an impossible feat in the past. While many can analyze data today in a much greater detail, there are many others who can actually retain more.
7. Google began to process about 20,000 terabytes, which is 20 petabytes of data per day in the year 2008. Today Google is actually able to answer about 40,000 queries per second today.
