Artificial Intelligence and Machine Learning systems proved that machines are better and faster than humans analyzing big data. Today, organizations have large datasets of patient data and insights about diseases through techniques like Genome Wide Association Studies (GWAS). Using AI, healthcare providers can analyze and interpret the available patient data more precisely for early diagnosis and better treatment. Today, it is possible to say whether a person has the chance to get cancer from a selfie using computer vision and machine learning to detect increased bilirubin levels in a person’s sclera, the white part of the eye. 

Why AI in Healthcare?

  1. Better patient care: AI can provide better patient care by detecting diseases earlier and offering more efficient treatment methods. According to Frost & Sullivan’s research, AI has the potential to improve healthcare outcomes by 30 – 40%.
  2. Data-driven decision-making: With machine learning algorithms, AI can document and offer more insights about a patient’s status and help doctors make better data-driven decisions by providing a better picture.
  3. Time & cost saving for administrative tasks: AI can handle administrative tasks like patient registration, patient data entry, and doctor scheduling for appointment requests.

AI Healthcare Market

In 2016 AI healthcare market was estimated to be around $0.66 B 

In 2021 AI market was expected to grow by 10 times to $6.7 billion. 

In 2019 estimate is 41.7% compound annual growth rate to $1.3 billion 

In 2025 the AI healthcare market is projected to be $13 billion

Over the last 4 years there has been a horizontal expansion in areas of implementation in healthcare. Companies like Cerner Corporation, IBM, McKesson Corporation ,GE Healthcare, Telstra Health, HotDocs, Health Engine are leading the healthcare revolution across the world.

So what are the areas where AI is  revolutionizing healthcare industry? Here is my list of top 18 areas of focus for AI Healthcare across the world in 2021-2022

Data Preprocessing - Binning ( Data Science and stuff)

A simple, yet powerful concept used during data analysis that categorizes the data into different buckets/bins. One important point to remember is that “binning” and “clustering” are not the same and vary considerably in logic and implementation. Binning as a method of data pre-processing. Data binning (or bucketing) groups data in bins (or buckets), in the sense that it replaces values contained into a small interval with a single representative value for that interval. Sometimes binning improves accuracy in predictive models.

For example, if you have census data, you can bin “age” into [0 to 5], [5 to 9], [10 to 14] and so on.

Alaska census data.


Sometimes, binning can improve accuracy of the predictive models. In addition, sometimes we use data binning to group a set of numerical values into a smaller number of bins to have a better understanding of the data distribution. 

As example, “a automobile price” is an attribute range from 5,000 to 45,500.
Using binning, we categorize the price into three bins: low price, medium price, and high
prices. In the actual automobile dataset, ”price" is a numerical variable ranging from 5188 to 45400,
it has 201 unique values. We can categorize them into 3 bins: low, medium, and high-priced cars.
In Python we can easily implement the binning: We would like 3 bins of equal binwidth, so
we need 4 numbers as dividers that are equal distance apart.
1) First we use the numpy function “linspace” to return the array “bins” that contains
4 equally spaced numbers over the specified interval of the price.                                                       2)We create a list “group_names “ that contains the different bin names.
3) We use the pandas function ”cut” to segment and sort the data values into bins.
We can then use histograms to visualize the distribution of the data after they’ve been
divided into bins. This is sample histogram that we plotted based on the binning that we applied in the price feature. From the histogram plot, it is clear that most cars have a low price, and only very few cars have high price.

Another example of binning employee data by salary.

Customer Segmentation using Machine Learning

When you get tons of unlabeled data and you want to find some pattern in data to be used for some purpose like segmenting the data on basis of certain characteristics machine learning algorithm can be a big help. Lets take a example of tons of customer data of Target or Amazon or Flipcart. 

To use this data for building some value added service like recommendation engine or showing customer latest treds that he might be interested in or even showing ads that are most appropriate for customer based on his gender, age, location etc we need to first classify the customer into different segments. 

According to a Forrester report, only 33% of companies using customer segmentation find it significantly impactful. The main reason companies fail is that they are still using traditional customer segmentation approaches, without leveraging the breadth of customer data and advanced analytics techniques available today.

What is Customer Segmentation?

Customer Segmentation is one the most important applications of unsupervised learning. Using clustering techniques, companies can identify the several segments of customers allowing them to target the potential user base. In this machine learning project, we will make use of K-means clustering which is the essential algorithm for clustering unlabeled dataset. Before ahead in this project, learn what actually customer segmentation is.

What is Behavioral Segmentation?

Traditional approaches to segmentation focused mainly on who customers are and segments were based on demographic attributes such as gender or age, and firmographic attributes like company size or industry. But just understanding who your customers are is not enough anymore.  Behavioral segmentation is about understanding customers not just by who they are, but by what they do, using insights derived from customers’ actions.

Behavioral Segmentation is a form of customer segmentation that is based on patterns of behavior displayed by customers as they interact with a company/brand or make a purchasing decision. It allows businesses to divide customers into groups according to their knowledge of, attitude towards, use of, or response to a product, service or brand.

Why Segment Customers by Behavior?

Here are four main advantages of grouping customers into different segments based on their behaviors:

  1. Higher Level Of Personalization. Understand how different groups of customers should be targeted with different offers, at the most appropriate times through their preferred channels, to effectively help them advance towards successful outcomes in their journeys.
  2. Behaviourial  Predictivity. Use historical behavioral patterns to predict and influence future customer behaviors and outcomes.
  3. Customer Prioritization. Make smarter decisions on how to best allocate time, budget and resources by identifying high-value customer segments and initiatives with the greatest potential business impact.
  4. Evaluating Segment Performance. Monitor growth patterns and changes in key customer segments over time to gauge business health and track performance against goals. At a high level, this means quantifying the size and value of customer segments, and tracking how “positive” and “negative” segments are growing or shrinking over time.
