Why Explainable AI is compulsory for Data Scientists?

Let’s understand why an explainable AI is making lot of fuss nowadays. Consider an example a person(consumer) Mr. X goes to bank for a personal loan and bank takes his demographic details, credit bureau details and last 6 month bank statement. After taking all the documents bank runs this on their production deployed machine Learning Model for checking whether this person will default on loan or not.

A complex ML model which is deployed on their production says that this person has 55% chances of getting default on his loan and subsequently bank rejects Mr. X personal loan application.

Now Mr X is very angry and puzzled about his application rejection. So he went to bank manager for the explanation why his personal loan application got rejected. He looks his application and got puzzled that his application is good for granting a loan but why model has predicted false. This chaos has created doubt in manager’s mind about each loan that was previously rejected by the machine learning model. Although accuracy of the model is more than 98% percentage. But still it fails to gain the trust.

Every data scientist wants to deploy model on production which has highest accuracy in prediction of output. Below is the graph shown between interpretation and accuracy of the model.

Interpreability Vs Accuracy of the Model

If you notice the increasing the accuracy of the model the interpreability of the model decrease significantly and that obstructs complex model to be used in production.

This is where Explainable AI rescue us. In Explainable AI does not only predict the outcome it also explain the process and features included to reach at the conclusion. Isn’t great right that model is explaining itself.

ML and AI application has reached to almost in each industry like Banking & Finance, Healthcare, Manufacturing, E commerce, etc. But still people are afraid to use the complex model in their field just because of they think that the complex machine learning model are black box and will not able to explain the output to businesses and stakeholders. I hope until now you have understood why Explainable AI is required for better and efficient use of machine learning and deep learning models.

Now, Let’s understand what is Explainable AI and How does it works ?

Explainable AI is set of tools and methods in Artificial Intelligence (AI) to explain the model output process that how an model has reached to particular output for a given data points.

Consider the above example where Mr. X loan has rejected and Bank Manager is not able to figure out why his application got rejected.Here an explainable can give the important features and their importance considered by the model to reach at this output. So now Manager has his report,

  1. He has more confidence on the model and it’s output.
  2. He can use more complex model as he is able to explain the output of the model to business and stakeholders.
  3. Now Mr. X got an explanation from bank about their loan rejection. He exactly knows what needs to be improved in order to get loan from the banks

Your Data Architecture: Simple Best Practices for Your Data Strategy

If you accumulate data on which you base your decision-making as an organization, you should probably think about your data architecture and possible best practices.

If you accumulate data on which you base your decision-making as an organization, you most probably need to think about your data architecture and consider possible best practices. Gaining a competitive edge, remaining customer-centric to the greatest extent possible, and streamlining processes to get on-the-button outcomes can all be traced back to an organization’s capacity to build a future-ready data architecture.

In what follows, we offer a short overview of the overarching capabilities of data architecture. These include user-centricity, elasticity, robustness, and the capacity to ensure the seamless flow of data at all times. Added to these are automation enablement, plus security and data governance considerations. These points from our checklist for what we perceive to be an anticipatory analytics ecosystem.

Getting Started With Data Lakes

Frameworks for Efficient Enterprise Analytics

The opportunities big data offers also come with very real challenges that many organizations are facing today. Often, it’s finding the most cost-effective, scalable way to store and process boundless volumes of data in multiple formats that come from a growing number of sources. Then organizations need the analytical capabilities and flexibility to turn this data into insights that can meet their specific business objectives.

This Refcard dives into how a data lake helps tackle these challenges at both ends — from its enhanced architecture that’s designed for efficient data ingestion, storage, and management to its advanced analytics functionality and performance flexibility. You’ll also explore key benefits and common use cases.

Introduction

As technology continues to evolve with new data sources, such as IoT sensors and social media churning out large volumes of data, there has never been a better time to discuss the possibilities and challenges of managing such data for varying analytical insights. In this Refcard, we dig deep into how data lakes solve the problem of storing and processing enormous amounts of data. While doing so, we also explore the benefits of data lakes, their use cases, and how they differ from data warehouses (DWHs).


This is a preview of the Getting Started With Data Lakes Refcard. To read the entire Refcard, please download the PDF from the link above.

Data Science: Advice for Aspiring Data Scientists | Experfy Insights

Around once a month, I get emailed by a student of some type asking how to get into Data Science, I’ve answered it enough that I decided to write it out here so I can link people to it. So if you’re one of those students, welcome!

I’ll segment this into basic advice, which can be found quite easily if you just google ‘how to get into data science’ and advice that is less common, but advice that I’ve found very useful over the years. I’ll start with the latter, and move on to basic advice. Obviously take this with a grain of salt as all advice comes with a bit of survivorship bias.

Less Basic Advice:

1. Find a solid community

2. Apply Data Science to Things you Enjoy

3. Minimize the ‘Clicks to Proof of Competence’

4. Learn Through Research or Entry Level Jobs
