Introduction
“If a man does not keep pace with his companions,
perhaps it is because he hears a different drummer.
Let him step to the music which he hears, however measured or far away.”
- Henry David Thoreau

The white paper. (or should it be black on white?)
Using Linear & Logistic Regression along with Collaborative Filtering Technique for Effective Training Program Deployment
Part I
“Say what?”
![Page 4: Effective Training Program Deployment](https://reader033.vdocuments.mx/reader033/viewer/2022061208/548751a4b47959e70c8b5440/html5/thumbnails/4.jpg)

Questions, a lot of questions.
What has deployment of training programs got to do with technology and why it’s in Tech Expo?
How many of you have a math/stats background? How many of you have data mining background? How many of you send your subordinates for
various training programs on a regular basis? How many of you have recently finished a
training program? How many of you have read my technical paper?

Version 1.0 Presenter: Deepak ManjarekarApril 10, 2023 5
Some new trends in corporate training
Emergence of learning organizations (LO) within corporations
Reverse trend in in-sourcing the corporate training programs to LOs
LOs viewed as “cost centers”
Low or no ROI or hard to measure ROI for LO
Organizations are grappling with poorly performing LOs
![Page 6: Effective Training Program Deployment](https://reader033.vdocuments.mx/reader033/viewer/2022061208/548751a4b47959e70c8b5440/html5/thumbnails/6.jpg)
Version 1.0 Presenter: Deepak ManjarekarApril 10, 2023 6
So why this matters to KPIT?
KPIT has a Learning Organization
The annual budget for KPIT’s LO has just been quadrupled from it’s last year’s annual budget
KPIT is planning to hire more than 1000 fresh recruits from college campuses across the country
There is a huge gap in what the engineers learn in schools and what they need to perform on a daily basis @KPIT
![Page 7: Effective Training Program Deployment](https://reader033.vdocuments.mx/reader033/viewer/2022061208/548751a4b47959e70c8b5440/html5/thumbnails/7.jpg)
Version 1.0 Presenter: Deepak ManjarekarApril 10, 2023 7
So why this matters to KPIT?
We will need to train these new recruits in appropriate technologies
We must make sure that our training dollars give us the biggest bang for the buck (acceptable ROI)
So effective training deployment becomes an imperative at KPIT’s LO
This paper is an attempt to apply statistical methods and predictive modeling in effective training program deployment to gain maximum ROI on training

Version 1.0 Presenter: Deepak ManjarekarApril 10, 2023 8
Main reasons why LOs fail?
Poorly organized training programs
Ineffective training delivery
Improper selection of trainees for the training program (Scope of the paper)
![Page 9: Effective Training Program Deployment](https://reader033.vdocuments.mx/reader033/viewer/2022061208/548751a4b47959e70c8b5440/html5/thumbnails/9.jpg)
Version 1.0 Presenter: Deepak ManjarekarApril 10, 2023 9
Reasons for improper selection of trainees
Favoritism Crying baby gets the milk Supervisors’ reluctance Many deserving candidates are busy in their day-
to-day work Supervisors want to maintain business continuity Peer pressure on employees Sending substitutes for the training when the
actual enrollee can’t attend Supply and demand for the training on a specific
technology Due to unforeseen circumstances
A lot of subjectivity goes in!

Version 1.0 Presenter: Deepak ManjarekarApril 10, 2023 10
The three stage OSCS Model The design of OSCS (Objective Subjective Candidate
Selection) model constitutes three major steps, First step will take out the bad subjectivity factor from trainee
selection process Two hypothesis testing
First hypothesis test using a survey mechanism and finding T-values
Second hypothesis testing using multi dimensional linear regression technique
Second step will make an objective candidate selection by using the results of the first step By building a predictive model using the logistic regression
technique
Third step will add the good subjectivity factor back into the selection process Self selection by the predicted candidate Using collaborative filtering technique to assess the
probability of the candidate liking the training based on the ratings given by other folks who are similar in profile and have undergone the training in past and rated it

The OSCS Model The design of OSCS model, the first step,
First hypothesis test using a survey mechanism and finding T-values
where µ is the population mean, x bar is the sample mean, and s is the estimator for population standard deviation and N is the sample size

Coming to a full circle
“If a man does not keep pace with his companions, perhaps it is because he hears a different
drummer. Let him step to the music which he hears,
however measured or far away.”
- Henry David Thoreau
“if a trainees feels like a fly on the wall in a classroom, perhaps it is because they were
incorrectly selected for that class. Let us put them thru the OSCS model and let them step into the right classroom however small or far away.”
- Deepak Manjarekar
