1. Stevens Institute of Technology School of Business Business Intelligence & Analytics Program A Snapshot of Data Science Student Poster Presentations Corporate Networking Event – November 28, 2017

2. This document reproduces the posters presented by students of the Business Intelligence & Analytics (BI&A) program at a Corporate Networking event held at Stevens Institute on November 28, 2017. The event was attended by over 80 company representatives and approximately 150 students and faculty members. The posters were presented by students at all stages in their academic programs from their first semester through their final semester. The research described in each poster was conducted under the guidance of a faculty member. The broad range of research topics and methodologies exhibited by the posters in this document reflects the diversity of faculty research interests and the practical nature of our program. For background, the first poster describes the BI&A program. Founded in spring 2012, with just 4 students, the program now has over 220 full-time and part-time masters of science students, 80 graduate certificate students and is ranked 7th in the nation by The Financial Engineer. As illustrated in the first poster, a distinctive feature of the program is its three-layer structure. In the professional skills layer, business and communication skills are developed through workshops, talks by industry leaders and an active student club. In the second layer, the 12-course curriculum covers the concepts and tools associated with database management, data warehousing, data and text mining, web mining, social network analytics, optimization and risk analytics. The curriculum culminates in a capstone course in which students work on a research project – often in conjunction with industry associates. Finally, in the technical skills layer, students attend a series of free weekend boot weekend camps that provide training in industry-standard software packages, such as SQL, R, SAS, Python and Hadoop. The 76 student posters in this document represent a broad array of research projects. We are proud of the quality and innovativeness of our students’ research and of their hard work and enthusiasm without which this event would have been impossible.

9. Improving a Non-Profit’s Home Page Team: Rush Kirubi, Thushara Elizabeth Tom Instructor: Chihoon Lee Business Intelligence & Analytics November 23, 2017 2 Experiment Design Methodology: Full factorial design with blocking. Factors & Levels: Responses: Drop Off rate Conclusion • The best setting is Purple Donate Button and No Slider relative to the other settings. • However the above is not substantial at 5% level of significance. • Since none of the factors are significant we opted to select those settings that minimize the page loading speed : No Slider, Testimonial with Text, Purple Donate Button. Data Time (blocking factor) was confounded with the 3-factor interaction, ABC. And thus assumed that this 3-factor interaction is negligible. Result • It was found that no factor significantly stood out. • The results of the experiment are shown below: ● Effect Test ● Normal Plot Motivation • Goal: Optimize True Mentor’s homepage to reduce the drop-off rate. • In turn, improving the quality score of the AdWords bids, leading to more ad exposures at the same or lesser expense. Limitations • We did not get enough time for replication due to the competition deadlines. • Blocking variable was difficult to accommodate. We manually took down the values at certain times of the day and night. Participating in Google's Online Marketing Challenge, we selected a nonprofit to run a digital marketing campaign. Part of our efforts involved optimizing the organization's home page to boost user engagement as measured by drop-off rates. We set up a full-factorial experiment (2 ^ 3) with time of day as the block variable. Put simply, we tested the donate button color, the presence of a slider and the type of testimonial. The type of testimonial was between one that was predominantly text and the other simply a photo with a caption. All the three factors were blocked on the time of day (daytime or nighttime). Empirically, the best setting was having no slider with a purple donate button. However, they were not robust enough to pass a statistical inference test. With the aforementioned settings, we additionally selected the no-slider option, as it reduces page speed, and its presence does not impact user-drop off rates.

10. Analyzing the Impact of Earthquakes Team: Fulin Jiang, Ruhui Luan, Zhen Ma, Gordon Oxley Instructor: Prof. Alkis Vazacopoulos Business Intelligence & Analytics Motivation • Earthquakes are one of the most destructive natural forces in the world that ravish entire cities with little notice • We wanted to analyze and visualize patterns in how earthquakes strike and damage specific locations historically in order to provide information on high risk areas and under prepared areas of the world • Earthquake features that were used include magnitude, source, focal depth, date, and type (nuclear or tectonic activity) • We also used an earthquake’s damaging effects using damage in US dollars, deaths, amount of houses damaged and destroyed, and injuries Financial Cost of EarthquakesCasualties due to Earthquakes Technology Utilized •Tableau was used for our analysis of earthquakes •We found tableau especially useful when visualizing the latitude and longitude data clearly identifying trends in the way earthquakes affect certain parts of the world •With the creation of 8 dashboards, we were able to analyze and visualize many different features of earthquakes including depth, source, and more Earthquake Map of the World • Based on the analysis of the number of deaths due to earthquakes, it is clear that a majority of high casualty events happen to coastal regions and many in the Indian subcontinent • We see a peak in deaths in 2010 due to the unfortunate number of casualties in Haiti underlining the fact that certain underdeveloped regions will suffer from increased casualties • We observe the same trend in high cost areas although the largest cost even occurred in Japan where the tsunami caused massive damages in 2011 Source: National Earthquake Information Center 3

11. Real Time Health Monitoring System Team: Ankit Kumar, Khushali Dave, Shruti Agarwal, Nirmala Seshadri Instructor: Prof. David Belanger m Architectural Approach The architecture flow will consist of following steps: 1. Data will be generated and stored in a file 2. Data will be stream lined using apache Kafka 3. A real-time data visualization will be setup using any of the visualization tool Tools used 1. JSON file parsing for initial data analysis 2. Apache Kafka for real time streaming 3. Arduino programming for pulling temperature data in real time 4. Python for data cleaning 5. Tableau for visualization Variables 1. Heart rate - Through Smart watch sensor 2. Steps Count – Through Smart watch 3. Body Temperature – Through Arduino Trigger Cases 1. Fever – High temp, low heart rate and steps 2. Long term unconsciousness – low heart rate , body temperature and steps count 3. Heart attack - high heart rate in a very short time interval Problem Statement To create a real-time health monitoring system which is user specific using sensors from a smart watch and/or an Arduino device. This application should be able to monitor health features like heart rate, steps count and body temperature in real time and should be able to warn the user or any emergency services of any undesired or serious condition. Results The last part of the project is to be able to visualize results in real time and to be able to plot streams of data and show a trigger result if any abnormal use case occurs. Business Intelligence & Analytics 4 Business Impact Our health data analysis application can pull data in real-time from device sensors. Using this system authorities, friends and relatives can easily monitor health of a loved one and can respond immediately in case of an emergency. From a business perspective this can attract customers suffering from a medical condition.

12. Zillow’s Home Value Prediction Team: Yilin Wu, Zhihao Chen, Jiaxing Li, Zhenzhen Liu, Ziyun Song Instructor: Prof. Alkiviadis Vazacopoulos Business Intelligence & Analytics 5 Motivation •Zillow Prize is challenging the data science community to help push the accuracy of the Zestimate even further(improving the median margin of error). •What we should do in this competition is to develop an algorithm that makes predictions about the the logerror for the months in Fall 2017 Technology •Python, Watson, Tableau for exploratory data analysis(EDA). •Python for data preprocessing and feature engineering. •Python to build the model. Competition Process Feature engineering Feature engineering part is the most important part of this competition. It is very important to find out feature importance to keep valuable features and drop useless ones. We also created new features that might make machine learning algorithms work better. EDA Data preprocessing Feature engineering Use 2016 data to train model Test predicted logerror of 2016 data Improve feature engineering part Figure out the best model and adjust the parameters Use both 2016 and 2017 data to train model Several improvements Final submission Modeling Somehow we found a magnificent gradient boost machine to deal with this problem(compared with Xgboost and LightGBM). It is called Catboost. Catboost builts oblivious decision trees and to prevent overfitting includes algorithm, which in some magical way reduces bias of the residuals. In addition it uses another scheme for calculating values in leaves. Also supports several options for converting categorical features based on statistics counting. In general Catboost is declared as an algorithm that can work with categorical features without preprocessing, is resistant to overfitting, and it is supposed that it can be used without wasting time and effort to hyperparameters selection. And of course most interesting that it can be more accurate. But learning is still very slow. On average, 7-8 times longer than LightGBM, 2-3 times longer than XGBoost. Before we train the model, it is necessary to define categorical features. In this case, we have 26 categorical features that can be trained in “catpool” Then we adjusted the parameters to get a better(not the best) result. Conclusion The final submission made a top 11% rank. It is pity that we are so close to the bronze medal which is top 10%. What we can do in the future is to play with the categorical features and keep adjusting the model.

13. Analysis of Opioid Prescriptions and Deaths Team: Pranjal Gandhi, Nishant Bhushan, Sunoj Karunanithi, Raunaq Thind Instructor: Alkis Vazacopoulos Business Intelligence & Analytics 6 The objective is to find the correlation between the prescription of drugs containing opioids and drug related deaths in the USA. What are opioids? Opioids are a class of drugs that include the illicit drug heroin as well as the licit prescription pain relievers oxycodone, hydrocodone, codeine, morphine, fentanyl and others. • Tableau for Visualizations. • R & Excel for cleaning the data and exploratory analysis. • The dataset is a subset of data sourced from cms.gov and contains prescription summaries of 250 common opioid and non-opioid drugs written by the medical professionals in 2014. • Number of deaths due to drug overdoses is leading the deaths occurring due to car accidents by a staggering 11,102 as per a report by the DEA. • In 2014, there were 4.3 Million people aged 12 years or older that were using Opioid based painkillers without prescriptions. • This led to substance abuse among almost 50% of the consumers. • 94% of respondents in a 2014 survey of people in treatment for opioid addiction said they chose to use heroin because prescription opioids were “far more expensive and harder to obtain.” ffmfnfn Analysis & Visualizations Results and Conclusion Facts & Figures Objective & Motivation Tools Used • We found the opioid prescriptions were too high for the prescribers following specialties: • Female Nurse Practitioners • Female Physician Assistants • Female and Male Family Practices • Female and Male Internal Medicines • Male Dentists The top 5 states with most %age of deaths due to overdoses are California, Ohio, Philadelphia, Florida and Texas. All of them had significantly high prescriptions of Hydrocodone- Acetaminophen followed by Oxycodone-Acetaminophen. Results and Conclusion

15. US Permanent Visa Application Visualization Team: Jing Li, Qidi Ying, Runtian Song, Jianjie Gao,Chang Lu Instructor: Alkiviadis Vazacopoulos Introduction Develop a descriptive analysis based on US permanent application data from 2012 to 2017 in Tableau and provide insights into visa decisions. Data explanation: 374363 applicants from 203 countries in 22 occupations. Descriptive Analysis Employer & Economic Sector Conclusion Business Intelligence & Analytics April 30th, 2015 8 Applications by State Applications by Country Top 10 companies that submit permanent visa applications. Education & Occupation Certified rate and denied rate among all education degrees We can observe that a high-school degree has significant denial rate in the graph. Doctorate’s degree has the lowest denial rate. Applicants with master's and bachelor’s are mostly working in Computer and Mathematical fields. Occupations which have highest certification rates. While High School applicants most working in Production Occupations that have certification rates lower than 5%. Our team used different attributes to analyze the relationships between visa applications and certification rates directly and indirectly. Application decisions are correlative with many vectors, such as education level, income, occupation and so on. In conclusion, applicants with higher education (Bachelor’s, Master’s, Doctorate’s) are mostly working in Computer and Mathematic areas, which has higher income is more likely to be certified. Applicants come from the countries which dominate the occupation have higher certification rate rate when go for in the related jobs. we found out the certification rate increased as time varied from 2012 to 2017. Applicants from different occupations have different nationality. Take the computer science and construction occupation distributed maps for example, we could see that certified applicants in computer domain mainly come from Indian and China, while construction occupations mainly come from Mexico.

Gandomi Results Clustering of Stocks during Recovery phase Clustering of Stocks during Recession phase K means plot shows that the stocks are clustered with similarities by their Sharpe ratio, volatility, and average return. There are 9 graphs in total, and 2 of them are displayed above for the expansion and recession phase. The x-axis shows the ticker/symbol of snp500 and the Y- axis shows the Cluster number. If we hover on the dot on the graph, it shows the ticker along with its cluster number, and the variable used for clustering. We used Silhouette and visually inspected the data points to find the optimal value of k, which turns out to be 22. Introduction OBJECTIVE We tried to provide a set of securities that behave similarly during a particular phase of the economic cycle. For this project, the creation of sub-asset classes is done only for large-cap Stocks. BACKGROUND Over time, developed economies such as the US are becoming more volatile and hence the underlying risk of securities has risen. This project aims to identify the risks & potential returns associated with different securities and to cluster similar stock similarities according to their Sharpe ratio, volatility, and an average return of stocks for a better analysis of the portfolio. Business Intelligence & Analytics 12 Data Acquire • Data of Large Cap Stocks & US Treasury Bonds is gathered directly using APIs. • The Data potentially consists of 2 time frames i.e. Recessionary & Expansionary Economy. Data Preprocessing • This segment included the application of formulae to calculate the pre-required parameters. (Eq 1,2,3,4). Analysis • This segment consists of K means clustering Analysis done on the Large Cap Stocks. (K = 22) (500 Stocks) • The clustered securities is then further tested for their correlation among the sub asset classes. Results • The results of K means clustering varies in the range (9 to 45) • There were some outliers in our analysis as well. Flow - Project Conclusion & Future Scope • With the above methodology, we have been able to develop a set of classes which behave in a similar fashion during each phase of the economic cycle. • The same methodology can be extended to different asset classes available online. • Application of Neural Networks can significantly reduce the error in cluster formation. • Also, application of different parameters such as Valuation, Solvency or Growth potential factors can be included for clustering purposes. • Next, we plan to add leading economic indicator data to identify the economic trend and to perform the relevant analysis. Mathematical Modelling • Here we take daily returns for all the 500 securities.
