About Rachel Warren

I am currently pursuing a PHD in Informatics at the University of California, Irvine advised by Paul Dourish and Melissa Mazmanian. I am broadly interested in predictive efforts in the public sector and risk assessments. I am spending this summer in Boston as a research intern with Microsoft Research New England. There, I am a part of the social media collective -- a group that studies the social, political, and legal implications of algorithmic and data technologies in society working. There I am working with Dr. danah boyd on a project exploring efforts in the disaster response community to incorporate social demographic information into risk planning. In my PhD I am part of an NSF funded effort to understand implications of new information technology in the fire service, particularly as it relates to community risk reduction efforts and EMS. I also study the impact of surveillance data and machine learning on the practice of public defenders and investigative journalists. In my previous life as a software engineer I worked in distributed computing and machine learning at Salesforce and co-authored a technical book called "High Performance Spark".

    Software engineer and data scientist for for Einstein Platform, a general machine learning platform which several machine learning apps at Salesforce including Einstein Prediction BuilderWorked with customers to identify problems with models by exploring data and running experiments using Python, Spark, SQL on AWS. - Designed pipeline for real time scoring metrics passing through 5 services - Collaborated on a cross-functional team of designers, lawyers, and data scientists at Salesforce to design data science features to allow customer design systems to surface and guard against issues of algorithmic bias in Salesforce’s machine learning suite- Spearheaded necessary Spark upgrade for Einstein Engagement Scoring pipeline which now serves more than a billion predictions per day.- Drove adoption of new experimentation framework among 20 person data science team by improving performance and usability.
  • Alpine Data Labs
    Engineer In Data Science
    Alpine Data Labs Apr 2015 - Sep 2017
    San Francisco, Ca, Us
    I work as a software engineer on our graphical analytics platform, which is built in Scala, Java, and Javascript and help build out our machine learning capabilities mostly with Spark.Accomplishments- Worked to develop an algorithm which optimizes Spark submission settings based on cluster size, and utilization, input data size and algorithm requirements.- Helped design, and am now on a two person team maintaining, Alpine's customer-facing extensibility framework. The framework enables customers to add their own Spark or database algorithms to our visual analytics engine. In particular, I:- - wrote much of our parsing engine for reading and writing files on HDFS including integrating support for Avro and Parquet- - added date time support for Hadoop- - added the ability to produce data visualization and well formatted tables in the framework- Co-Authored Alpine's first NLP package with Spark. We added support for stop-word removal, sentence tokenization, stemming, n-gram parsing, TF-IDF, and LDA with Spark.- Added support for Collaborative Filtering on Hadoop. Our implementation is based on that in Spark MLlib, but also includes support for string keys and ranking predictions for users.- Worked to rapidly develop customer-facing data processing routines at scale including, calculating rank statistics, custom aggregations on wide data, and computing inferential statistics.- Lead formal trainings for customers from organizations around the world on using our extensibility framework. Also trained the members of our data science team (who had no pervious Spark experience) to implement their own algorithms in our extensibility framework.

    As a continuation of my work for the Wesleyan media project, I built an application to help us better collect data for my senior capstone project in computer science under the aegis of Computer Science Professor Norman Danner. The application scrapes articles from an academic database, uses a regular expressions algorithm to parse the articles into text attribute strings, and then uses a machine learning algorithm I developed using an ML tool called WEKA, to discard the articles that are not relevant to the analysis. Accomplishments: Ultimately, the application reduced the number of articles which had to be scored by hand by 20%.
