ASA SLDS JSM 2017 student paper competition

Call for papers

Student Paper Competition - JSM 2017
(July 29th-Aug 3rd, 2017, Baltimore, MD)
ASA Section on Statistical Learning and Data Science
Sponsored by SLDS

Key dates:
• Abstracts due December 15th, 2016
• Full papers due January 4th, 2017

The Section on Statistical Learning and Data Science (SLDS) of the American Statistical Association (ASA) is sponsoring a student paper competition for the 2017 Joint Statistical Meetings in Baltimore, MD, on July 29th-August 3rd, 2017.

The paper might be an original methodological research or a real-world application (from various fields including but not limited to marketing, pharmaceutical, genomics, bioinformatics, imaging, defense, business, public health) that uses principles and methods in statistical learning and data science.

Papers that have been accepted for publication are NOT eligible for the competition. Selected winners will present their papers in a designated topic-contributed session at the 2017 JSM in Chicago, IL organized by the award committee. In this session, they will be presented a monetary prize and an award certificate. Winning papers will be recommended for submission to Statistical Analysis and Data Mining: The ASA Data Science Journal, which is the flagship journal of the SLDS Section.

Graduate or undergraduate students who are enrolled in Fall 2016 or Winter/Spring 2017 are eligible to participate. The applicant MUST be the first author of the paper.

Abstracts (up to 1000 characters) are due 12:00 PM (noon) EST on December 15th, 2016 and shall be submitted via this Abstract submission form (https://goo.gl/forms/jkPrjVuRbeLUufGm2). ONLY students who submit their abstracts on time are eligible for submitting full papers after 12/15/2016.

Full papers and other application materials must be submitted electronically (in PDF, see instruction below) to Professor Tian Zheng (tian.zheng@columbia.edu) by 12:00 PM (noon) EST on Wednesday, January 4th, 2017. ONLY students who submit their abstracts by 12/15/2016 are eligible for submitting full papers.

All full paper email entries must include the following:

1. An email message contains:
• List of authors and contact information;
• Abstract with no more than 1000 characters.
2. Unblinded manuscript - double-spaced with no more than 25 pages including figures, tables, references and appendix. Please use 11pt fonts (preferably Arial or Helvetical) and 1 inch margins all around.
3. Blinded versions of the abstract and manuscript (with no authors nor references that could easily lead to author identification).
4. A reference letter from a faculty member familiar with the student's work which MUST include a verification of the applicant's student status and, in the case of joint authorship, should indicate the fraction of the applicant's contribution to the manuscript.

All materials must be in English.

Entries will be reviewed by the Student Paper Competition Award committee. The selection criteria used by the committee will include statistical novelty, innovation and significance of the contribution to the field of application as well as the professional quality of the manuscript.

This year’s student competition is sponsored ASA SLDS and is chaired by Professor Tian Zheng (Columbia University). Award announcements will be made in mid-January 2017. For inquiries, please contact Professor Tian Zheng (tian.zheng@columbia.edu).

Resources for data analytics at Columbia

I got an email asking for resources (other than courses) for data analytics at Columbia. This is what I wrote in reply:

• The library runs workshops on analytics: http://library.columbia.edu/research/workshops.html.  

• You can join student organizations such as Columbia Data Science Society (http://datascience.columbia.edu/columbia-data-science-society) and Columbia Statistics Club (https://www.facebook.com/columbiastatisticsclub/). Both groups organizes hack-athons and meetups.  

• The Data Science Institute (DSI) organizes events and seminars for a wide range of audience. The institute industry innovation series features speakers from industry have especially interesting talks (https://industry.datascience.columbia.edu/innovation).

ADS alum Yuhan Sun's summer intern at UNICEF

An Spring 2016 alum from our Applied Data Science course , Yuhan Sun (MA in Statistics, Columbia University), spent the past summer as a data scientist at UNICEF. She extended a Shiny app that provides a web-based application for generating child mortality estimates. These estimates are computed from empirical data using the United Nations Inter-agency Group for Child Mortality Estimation (UN IGME) methodology. According to Ms. Lucia Hug from UNICEF,

"The UN IGME methodology applies a curve fitting method to derive trend estimates by using a Bayesian B-splines bias-reduction model to empirical of under-five and infant mortality rates. The method also extrapolates the trend estimates to a defined time point."

In this project, Yuhan applied her skills on Shiny app development learnt during our ADS course to meet the needs of this task. She said:

"Shiny provides a feasible approach for non-cs people to build a web application. It is an effective and time efficient way to build an application which uses the existing R codes for the Bayesian B-spline bias-reduction model. It also enables users to use the UN IGME methodology without being familiar with running R codes. It allows to apply the model to new empirical data and to review the new estimates graphically. It also offers the possibility to visualize the results and to adjust parameters according to the users’ needs."

Ms. Hug said: "Mortality rates among young children are a key output indicator for child health and well-being, and, more broadly, for social and economic development. It is a closely watched public health indicator because it reflects the access of children and communities to basic health interventions such as vaccination, to medical treatment of infectious diseases and to adequate nutrition."

Yuhan is also working on some cool visualizations as part of her internship.

A happy birthday in numbers

On my birthday, I received a total of 65 "happy birthday!" messages (in either Chinese or English) via social messaging. For the first year, I got birthday wishes from LinkedIn. I thought it'd be fun to visualize using Tableau some basic information about these social messages, as a snapshot of a subset of my social network.

• More than 3/4 of my birthday wishing social network are Chinese.
• The biggest three groups in my current online social networks of nice people are via family, via work, and via kids, which are the three main (if not ONLY) occasions of my social interactions. 
• My Chinese friends are active on Wechat and my non-Chinese friends are mostly on facebook.
• Facebook and LinkedIn both post reminders about upcoming birthdays. From the trends, it seems that LinkedIn users are only active in the morning or in the evening, while Facebook users (at least those among my FB friends) are more active during the day and around meal times. 

A semester of data science fun with new teaching approaches

This semester I am teaching GU4243/GR5243 Applied Data Science (syllabus) and GR5705 Introduction to Data Science (syllabus). ADS will be a Project-Based Learning (PBL) class and IDS will be using the flipped classroom approach.

Applied Data Science

Another semester of data science fun is just around the corner.
