|Title: Lung Cancer Survival Prediction Challenge |
Time: 11:00 – 13:00
Every year 1.9 million people are diagnosed with Non-Small Cell Lung Cancer (NSCLC). Only 25% of those will survive 5 years beyond their diagnosis, with prognosis depending on many factors including demographics, clinical characteristics, and genetic alterations, among others.
Survival Machine Learning models could enable us to better predict prognosis for individual patients, which in turn has real world clinical applications for improving treatment and our understanding of NSCLC. Additionally, representations learned by fitting Survival Machine Learning models on NSCLC data could be used to stratify patients and obtain clinical clusters or phenotypes that give us insights on how to better categorize NSCLCs.
In this challenge you will predict the risk of overall death using clinical EHR data from around 75,000 advanced NSCLC patients provided by Flatiron Health. The features consist of patient characteristics such as demographic information, vital sign data, and biomarkers.

|Title: PRINCE Out-of-distribution Generalization Challenge|
The goal is to learn a mapping from a set of features (X) to a label (y) that generalizes well across environments that have not been seen in training (a.k.a. out-of-distribution generalization). This challenge uses data from Criteo, an advertising company and environments correspond to different business types (e.g. Retail, Travel, Insurance, Classifieds etc). Such environments exhibit challenging distribution shifts whilst still depending on the same underlying causal mechanism. Will you be able to infer shoppers behavior on retail merchants while seeing only travel and insurance data ?

|Title: Expedia Group Cross-brand Lodging Recommendation|
In online platforms it is often the case to have multiple brands under the same group which may target different customer profiles. For example, in the hospitality domain Expedia Group has multiple brands like Brand Expedia, Hotels.com, Orbitz or Vrbo. In this context, being able to provide cross-brand recommendations to travelers is an important task as it can improve traveler experience across different point of sales. In this challenge we propose a cross-brand recommendation task where the participants will be provided with traveler actions in a source brand (e.g. property clicks) and asked to predict actions in target brands. The objective is to improve the recommendations in target brands using the data from a source brand.
