Datahack is the first data-driven hackathon in Israel, designed to bring together the Israeli data community. This year I’ll be mentoring and wanted to provide some preliminary ideas for how to tackle some this years challenges.
The Challenge: Participants receive low resolution and occluded images of famous actors and will be asked to identify them.
Evaluation: This is a leader-board type competition. Participants will be ranked by model performance. Exact details soon.

Ideas
Sample a few frame pass them through a pretrained image super resolution model and then pass the result through a cognitive service trained for celebrity face recognition.
Take a Large Scale Celebrity Faces Data-set downsample the images and try to predict the original faces by combining a Image Super Resolution Network with an image classifier.
Try to recover the original video clips from youtube by pulling and sampling the first page of results for top celebrities and see if you can find a match.
Run video clips through the free Video Indexer Service demo to get a baseline.

The Challenge: Given access to traffic data of ~ 1M devices, find the devices that misbehave
Evaluation:As this is an unsupervised challenge, the evaluation process will be a mix of classical leaderboard evaluation and in-person review of the models used.

Ideas
Use an trial cloud service to try to make a quick and dirty Anomaly detection baseline
Use the anomaly detection feature of Facebooks prophet library to get an open source baseline
Use the TagAnomaly developed by Omri Mendels to annotate some of the anomalies and train a semi-supervised model.
Check out the twitter anomaly detection sdk even though it isn’t maintained.
The Challenge: In our lead-scoring challenge you’ll get 6 months of anonymous user-events (over 4B records) and help us find the crème de la crème, pick of the litter, the best of the best customer that could use our extra attention and get the most out of monday.com!
Evaluation: This is a leader-board type competition. Participants will be ranked by model performance.
Ideas:
Hard to know yet since the haven’t released the data but step one would be tor build a baseline model using AutoML you can get free trial for the datahack here.
Resources:
The Challenge: Create art with Data and AI.
Evaluation: This is an open-ended vertical competition. Participants will be judged by a panel from Lightricks.
Ideas:
Generative ART with nvidia GANs
Image Colorization Deoldify
Tensorflow.js art
