The schedule for the 2019 edition is published here: https://hasgeek.com/anthillinside/2019/schedule

The conference has three tracks:

  1. Talks in the main conference hall track
  2. Poster sessions featuring novel ideas and projects in the poster session track
  3. Birds of Feather (BOF) sessions for practitioners who want to use the Anthill Inside forum to discuss:
    - Myths and realities of labelling datasets for Deep Learning.
    - Practical experience with using Knowledge Graphs for different use cases.
    - Interpretability and its application in different contexts; challenges with GDPR and intepreting datasets.
    - Pros and cons of using custom and open source tooling for AI/DL/ML.

Who should attend Anthill Inside:

Anthill Inside is a platform for:

  1. Data scientists
  2. AI, DL and ML engineers
  3. Cloud providers
  4. Companies which make tooling for AI, ML and Deep Learning

Learning to Rank recommendation - Ranknet to LambdaMART to Groupwise scoring functions - experiments, introduction to Tensorflow Ranking

Submitted Apr 29, 2019

Search and product recommendations are typically served using CF, MF, FM techniques, content/context/sequence based methods or using learning to rank framework which is more generic than rest. Evolving from traditional classification and regression modeling methods, the loss functions, gradients, computation tricks have evolved to suit ranking problems (point wise to pair wise to list wise solutions) in this ambit. Learning to rank models such as LambdaRank and LambdaMart models (developed by Microsoft research group) are very competitive and have shown success in many instances (Kaggle, Yandex, Yahoo rankings challenges). More recently, multi-item group wise scoring functions were proposed by google research group (2018). This talk would focus on our team’s journey (what worked and what didn’t) in using these methods for ranking, importance of sampling, importance of measuring performance using multiple metrics (not just NDCG), importance of offline and online evaluations for ranking, and compare Ranknet, LambdaRank/LambdaMART, Listnet and multi-item group-wise scoring functions.

Outline

  1. Introduction to learning to rank framework.
    1. Metrics for evaluation.
    2. Description of the methods (Ranknet, LambdaRank, lamdaMART, multi-item group-wise scoring functions)
    3. Integrating diverse feature types, feature engineering, transformations and sampling of items.
    4. Results.
    5. Summary
    6. Future work
