Artificial Intelligence is nothing but Augmented Intelligence


Entity Embeddings

Entity Embeddings is an upcoming technique for applying deep learning to tabular data. It involves representing the categorical data of an information systems entity with multiple dimensions. It is being used in several production systems at companies such as OpenAI, Google, Instacart, Twitter, etc.

Kaytek Founder Director Mr Mahesh Khatri has spoken on Entity Embeddings at various global forums.

Kaytek Founder Director Mr Mahesh Khatri spoke at the Deep Learning NYC Meetup Group in New York, USA on Thursday 6th June 2019 on the topic Entity Embeddings & Pytorch in the Enterprise". The event was organized by Mr Kris Skrinak of Amazon Web Services (AWS) & Ms Pallavi Gadgil,the leaders of the Deep Learning NYC Meetup Group. Thanks to them and also Amazon for hosting the above meet at their New York office. Also, a big thanks to to all the participants who came and actively interacted on the topic.

Presentation Overview - In his presentation, Mr Mahesh Khatri presented the concept along with examining it's usage in the following 3 papers :

Kaggle Competition winner papers - Artificial Neural Networks Applied to Taxi Destination Prediction (Yoshua Bengio’s team - 31st July 2015) &

Entity Embeddings of Categorical Variables (22nd April 2016) &

Google Research paper - Deep Neural Networks for YouTube Recommendations (16th September 2016).

Entity Embeddings Deep Dive - Entity Embeddings are used by some of the largest and smartest organizations on the planet like Amazon, Facebook, Google, Twitter and many more in their gigantic internal production scale machine learning systems. TwimlAI (This Week in Machine Learning & AI) just published Mahesh Khatri's presentation on Entity Embedding Deep Dive at their North America Meetup on 13th November 2018.

An explanation of Entity Embeddings & usage in the following research papers was covered :

- Cheng Guo's paper - Entity Embeddings of Categorical Variables which was a 3rd prize winner at a Kaggle competion

- Yoshua Bengio's paper - Artificial Neural Networks Applied to Taxi Destination Prediction which won the 1st prize at the ECML/PKDD discovery challenge &

- Google AI Research paper - Deep Neural Networks for YouTube Recommendations

All of those who are interested in learning about contemporary usage of Entity Embeddings may find the presentation useful. A Basic Knowledge of Neural Networks is needed for understanding this presentation. Thanks to Sam Charrington & TwimlAI for their support in hosting this event. - 10th December 2018.
