BGU's Data Science Community

Who We Are

DiSCo is a data science community at Ben-Gurion University of the Negev. We are a community with a goal of overall development and growth of students and professional enthusiasts in Beer-Sheva in the areas of data mining, data science, and machine learning. DiSCo meetups act as a platform to provide hands-on experience in data science tools and techniques, while networking and having fun. We are all about learning, snacks and friendship.

Our Motivation

Data science, also known as data-driven science, is an interdisciplinary field of scientific methods, processes, and systems to extract knowledge or insights from data in various forms, either structured or unstructured, similar to data mining. Harvard Business Review called it "The Sexiest Job of the 21st Century."

The motivation of this club is to serve as a platform for BGU data science enthusiasts to pursue their interests in data science to learn, network, collaborate, create, and innovate.



We invite you to join us on a panel with Ben-Gurion University graduates who are currently working in the industry in Data Science positions or are PhD students.
During the event, the graduates will tell us about themselves, their day-to-day, job challenges, how to properly prepare for job interviews and with what tools to get into the industry. The panel:

  • Yafit Zohar Laadan, Data Scientist & NLP Researcher at, Master's degree in Software and Information Systems Engineering.

  • Igal Mazor, Senior Manager, Data Science at Genesys, Master's degree in Industrial Engineering - Machine Learning

  • Ran Taig, Lead Data Scientist at Lusha, PhD degree in Computer Science.

  • Racheli Abo, Senior Data Science at Riskified, Master's degree in Industrial Engineering

  • Liel Cohen-Lavi, PhD. student in Bioinformatics and Data Science, Master's degree in Industrial Engineering - Artificial Intelligence.

Natural Language Processing - GPT3

In the last two years, we have seen some amazing breakthroughs in natural language processing and generation. But do computers really understand language? In this lecture, I would explain how computers understand language what is so special about GPT3 and other recent language models, the cool things we can do with them and what might be the future of the area.

University Research VS. Industry Research

What will be discussed in the lecture:

  1. Where do you get your data?

  2. The skill set you actually use: programming? statistics? math?

  3. How to research in teams?

  4. Does the data scientist deliver reports or products?

  5. The workspace: Python, R, Pycharm, Jupyter, VScode,...

  6. The type of employers: startups, big-tech, growth, ...

Introduction to PU Learning

PU Learning is a semi-supervised classification learning scenario. PU classification involves a training set in which just part of the data is labeled as positive, while the rest is unlabeled - containing both positive and negative data in unknown relative ratios. In this talk we will discuss how this scenario is defined formally, why traditional classification techniques do not translate to it naturally, and how - using some basic assumptions - both metrics and model learning can be adapted to (partially) overcome the challenge PU learning poses.

Git Workshop

Git is software for tracking changes in any set of files, usually used for coordinating work among programmers collaboratively developing source code during software development.
This workshop demonstrates some of the key features of Git. It does so via a set of straightforward examples for possible uses and basic commands.
This is a hands-on workshop.

Anomaly Detection on Big Data

Anomaly detection is a well-studied area of research; however, anomaly detection techniques often underperform while dealing with big data. The high-volume, high-velocity, and high-dimensionality make many of the anomaly detection algorithms obsolete. This talk will present how we overcome our data challenges by training billions of simple models to create a distribution approximation to search for anomalies in the number of observations across billions of different groups.

Andres Asaravicius leads a team of experienced Data Scientists in Riskified. Over the years, he has led end-to-end researches and has been a key player in building the data science infrastructure. Even though his background is in Social Sciences, he is passionate about Machine Learning technologies and infrastructure.

Introduction to NLP

Have you ever wondered if computers can understand human languages? 
Since 1950, people have been trying to crack the secret of understanding the human language. In his famous Turing test, Alan Turing defined conversation between a human being and a computer as a criterion for intelligence.  The complexity of understanding the human language can prove his argument. In this lecture, Gal will explain how to deal with textual data, cover the main architectures for analyzing text and show how things work in practice. 

About Gal, 
Gal Hever is a graduate of the "Meitar" program in the Department of Industrial Engineering and Management in Ben-Gurion with a specialization in data science. Today, she is a Data Scientist at VisionMap. Gal initiated and established the DataNights track in the Datahack community. For those of you who are unfamiliar, this is a track with excellent online lectures in the field of Data Science. In addition, Gal is currently a mentor for women looking for a job in the high-tech and data science field in the Facebook group Coming and she has lots of tips to share with us.
