- 1. Platform for Data Scientists Binu K, Architect Analytics Platform www.subex.com 1
- 3. Data and Analytics Capture • Acquire, extract, parse, aggregate Analyze • Feature Engineering, Exploratory analysis Modelling • Machine learning, Statistics, Optimisation Analytics Output • Application to live data - Trends, Prediction Communication of Results • Dashboards and Reports The process & pain areas Time taken for data into insights – Few Months 3 60 – 75% Credits : Forbes
- 4. Advantages www.subex.com 4 Automate repeated routine jobs • Data load • Preprocessing Maximum resource Utilization • Scheduling job overnight Focus more on business • Look different use cases • Solution areas Integrated tool box • Combine tools into one environment
- 5. Expectations Workbench • Exploratory Data Analysis • Advanced Modelling • Distributed Architecture Bespoke Algorithms • Customized ML algorithms • Custom Approaches Industrialization • Packaged Analytics Platform www.subex.com 5
- 7. Work Bench EDA 7 Querying capabilities • Pointed queries • Aggregations • Partitioning • Windowing • Analytical functions Descriptive Stats • Univariate analysis • Bivariate analysis Predictive Modeling • Building and testing • Ensemble
- 9. Customization • Decision Trees/Random Forests • Handling categorical values • Identify top reason • Custom node labelling • K-Means • Weighted Distance • Geospatial distance - Harvesine distance • Social Network Analysis • Build call network • Community detection • Influencer identification Domain & scale www.subex.com 9
- 11. Objective www.subex.com 11 Pareto Analysis Example Selection of a limited subset which produces significant overall effect. Two comparable metrics with unbalanced magnitudes of cause & effect are identified Samples • Smart phones constitute 27% of all handsets but contribute to 95% of all mobile traffic • 75% of the of the revenue is generated from 15% of distinct rate plans • 10% of distinct problem areas are responsible for 83% of total complaints Use cases Can be used to identify impact of a causal metric on a outcome metric.

- 13. Recipe for Success Regardless of what some software vendor advertisements may claim, you can’t just purchase some Analytics software, install it, sit back, and watch it solve all your problems. Right combination of domain (business acumen) and analytics is required to solve any business problem www.subex.com 13 “There is a tendency of solving one’s problems by means of much equipment rather than thought." Alan Turing.

Editor's Notes
- Majority of time taken is data cleansing. Reasons: The coding of the data is inconsistent (e.g. date is sometimes Day-Month-Year, and sometimes Month-Day-Year) Data is made available in separate tables, but merge keys for join are missing Dependent variables for the analysis are largely missing Many fields appear to contain wild (clearly impossible) values Ambiguity regarding whether a value is valid or missing (e.g. age is 99) The unit of observation in the data is not appropriate for analysis (e.g transaction level data but analysis is required at customer level) http://www.forbes.com/sites/gilpress/2016/03/23/data-preparation-most-time-consuming-least-enjoyable-data-science-task-survey-says/#57bc6a597f75
- Query on profile and raw table; H2O is an open source, in-memory, distributed, fast, and scalable machine learning and predictive analytics platform that allows you to build machine learning models on big data and provides easy productionalization of those models in an enterprise environment. H2O’s core code is written in Java. Inside H2O, a Distributed Key/Value store is used to access and reference data, models, objects, etc., across all nodes and machines. The algorithms are implemented on top of H2O’s distributed Map/Reduce framework and utilize the Java Fork/Join framework for multi-threading. H2O’s REST API allows access to all the capabilities of H2O from an external program or script via JSON over HTTP. The Rest API is used by H2O’s web interface (Flow UI), R binding (H2O-R), and Python binding (H2O-Python). Sparkling Water allows users to combine the fast, scalable machine learning algorithms of H2O with the capabilities of Spark. With Sparkling Water, users can drive computation from Scala/R/Python and utilize the H2O Flow UI, providing an ideal machine learning platform for application developers http://blog.cloudera.com/blog/2015/10/how-to-build-a-machine-learning-app-using-sparkling-water-and-apache-spark/
- Transform analytics insights to business insights Not just an algorithm. Infused with business contexts Customized to @ Telecom Scale Association - Both categorical – Cramers V; Catg & Conti : simple linear regression with categorical as explanatory variable - One-way ANOVA
- The Pareto principle is a principle, named after economist Vilfredo Pareto, that specifies an unequal relationship between inputs and outputs.. It states that, for many events, roughly 80% of the effects come from 20% of the causes. ... Pareto developed both concepts in the context of the distribution of income and wealth among the population.
