Session type: Short talk of 20 mins

Abstract

Matching the same and similar products is a problem fundamental to the online retail industry with multiple applications spanning across price optimization, recommending similar or substitute products to customers, understanding gaps in product assortments, and counterfeit product detection.
Given that that there are no standard product identifiers, catalog data is often noisy, incomplete and nonstandard, product matching is a challenging problem at scale. In this talk we will define the problem of product matching and discuss what makes it a hard problem. We will then discuss our approaches towards addressing it.
We use an ensemble of text and image-based approaches: content-based image retrieval (that uses a novel hashing technique that we developed), CNN, language model based word embeddings (BERT and Transformer), and techniques from classical machine learning.
We have built an automated pipeline that adapts based on the category of products it is handling.

Outline

  • The merger of text & image signals
  • Importance & use of RNNs & CNNs
  • Handling matching at scale: volume & variety (multiple product categories)
  • The feedback loop for an effective & robust system

    Hello Aayushi/Byom Kesh,

    Thank you for submitting a proposal. To proceed with evaluation, we need to see detailed slides for your proposal. The link you’ve added needs to be edited to make it publicly accessible. Your slides must cover the following:

    • Problem statement/context, which the audience can relate to and understand. The problem statement has to be a problem (based on this context) that can be generalized for all.
    • What were the tools/options available in the market to solve this problem? How did you evaluate alternatives, and what metrics did you use for the evaluation?
    • Why did you pick the option that you did?
    • Explain how the situation was before the solution you picked/built and how it changed after implementing the solution you picked and built? Show before-after scenario comparisons & metrics.
    • What compromises/trade-offs did you have to make in this process?
    • What is the one takeaway that you want participants to go back with at the end of this talk? What is it that participants should learn/be cautious about when solving similar problems?
    • Is the tool free/open-source? If not, what can the audience takeaway from the talk?

    We need to see the updated slides on or before 21 May in order to close the decision on your proposal. If we do not receive an update by 21 May we’ll move the proposal for consideration at a future event.

      Hi Abhishek,

      Thank you for your message. I have changed the sharing settings and the deck is now publicaly accessible.

      We will be re-structuring the deck based on your feedback and will surely send it by 21st May.

      Also, would like to follow up on the other proposal I’d sumbitted, - “Building a large-scale Data as a Service (DaaS) platform to consistently deliver high-quality datasets”. Do you want us to re-structure it in the same manner and re-submit it?

      Thanks,
      Aayushi

      • Abhishek Balaji (@booleanbalaji) Reviewer 7 months ago

        Sure, I’m adding comments separately on the other proposal as well.

        • Aayushi Pathak (@09aayushi) Proposer 7 months ago

          Great! Thanks. :)

    In addition, please elaborate on how this proposal improves on other talks we’ve received on product matching (needle in haystack problems) - https://hasgeek.com/fifthelephant/2019/proposals/similarity-search-for-product-matching-semantics3-HXoeFVrR58xqezWjKrNY8Q

    Also, the above link can’t be reached.

    • Abhishek Balaji (@booleanbalaji) Reviewer 7 months ago

      Fixed it.

  • Aayushi Pathak (@09aayushi) Proposer 6 months ago

    @Abhishek, the slide has been updated. Kindly review.

    Thanks,
    Aayushi

    Hi Aayushi/Byom Kesh,

    Thanks for the updates. We will not be able to consider this proposal for The Fifth Elephant 2019 in Bangalore since the topic has already been covered extensively and there’s nothing novel in the proposal. We recognize that this is an important problem to solve, and hence have put together a Birds of Feather session on related problems. We’ll reach out to you soon when we have the session details finalized.

    Hi Abhishek,

    Can you please share the details for ‘Birds of Feather’ session?

    Thanks,
    Aayushi
