Recommender System
What is RecSys? Value of Recommendation
RecSys Modeling and Applications
 Aims to predict user preferences based on
historical activity and implicit / explicit
feedback
 Helps in presenting the most relevant
information (e.g. list of products / services)
Collaborative filtering: User’s
behavior, similar users
Content-based filtering: using
discrete characteristic of items
*Movies, music, news, books,
search queries, social tags, etc.
* Financial services, insurance
Intel business unites (BUs), sales
and marketing
 Nearest Neighbor modeling
 Matrix factorization and
factorization machines
 Classification learning model

RM Change Risk Evaluation
RM’s Customer Ranking
•Rank clients under an RM in
terms of their net worth and
brokerage
Change in Ranking
•Determine changes in
ranking of net worth and
brokerage
Develop Classification Model
•Use RM and client features
to determine whether a
client will rank worse after
an RM change
• Evaluating the impact of the RM change by identifying the customers at risk who are associated with/managed by the
same RM leaving the organization :
Take 90 days before
and after an RM
change
Sum pre and post
brokerage and net
worth
Sort clients according
to brokerage and net
worth ranking
Develop model to
predict change in
ranking on RM change
• Results based on changes in net worth and brokerage revenue:
Accuracy Sensitivity Specificity Prevalence Kappa AUC
Brokerage 74.53% 70.92% 77.02% 40.88% 0.4764 83.09%

Cluster Discovery, Description & Visualization using Predicted Labels
Cluster Discovery
 Cluster analysis can help identify groups or clusters of similar clients.
 Functional description of each cluster can help make inferences on client dormancy.
 Cluster analysis can be performed for predicted dormants.
 Features such as traded days, net worth, turnover (TO) may group clients into separate
clusters.

Cluster Description
Each cluster can be used as a business action item for reaching out to clients
 Represent each cluster by a single point in the feature space.
 Make inferences on client behavior from these representation.

Mobile Brokerage Analysis
 For example: In June there are 8693 clients on mobile, 5390 clients remained till
Jan 2016. We computed different brokerage features based on the client
present in June.
Take the number
of mobile and
non-mobile users
in June 2016

set clients in the
following months

Text analytics
Identifying Important News Item News Summarization
Automatic summarization is the process of reducing a text
document with computer program in order to create summary
that retains the most important points of the original
document
Creation of algorithm that separates out market/ stock
relevant news and filters out noise using machine learning
 Supervised and unsupervised machine learning
approaches can be tried to enhance the performance of
the model.
 Latest research from Natural Language Processing(NLP)
and text analytics can yield interesting results.
Extraction
•Includes topic detection,
scoring and extraction of
most relevant text
segment
ML
Techniques
•Techniques like RNNLM
(recurrent neural network
language modeling and
recurrent convolutional
neural networks will be
applied
