We are inviting proposals for:

  3. Sponsored sessions (limited slots available; subject to editorial scrutiny and approval).
  4. Hands-on workshops, of 3 and 6 hour duration.
  5. Off The Record (OTR) and Birds of a Feather (BOF) sessions for 90 mins each.
  6. 5- and 10-min demos.
  7. Panel discussions.

We accept talks on open source technology, with the following caveats:

  1. If the technology or solution is proprietary, and you want to speak about your proprietary solution to make a pitch to the audience, you should pick up sponsored session. This involves paying for the speaking slot.
  2. If your solution / technology is available through a freemium model, it will fall under sponsored session category. 3. If the technology or solution is in the process of being open sourced, we will consider the talk only if the solution is open sourced at least two months before the conference.

If your tech stack is closed source, you should consider proposing a talk explaining your choices in the first place; what options you considered (business-wise and technology-wise) before you made the decision to build your own solution; what is your specific use case that left you without existing options and necessitated you to build your own solution.

Selection criteria:

The criteria for selecting proposals, in the order of importance, are:

  • Key insight or take away: what can you share with participants that will help them in their work and in thinking about the problem?
  • Structure of the talk and flow of content: a detailed outline helps us understand the focus of the talk, and the clarity of your thought process.
  • Ability to communicate succinctly, and how you engage with the audience. You must submit link to a two-minute preview video explaining what your talk is about, and what is the key takeaway for the audience.

We do not allow marketing or hiring pitches in talks or discussions. For a list of what is acceptable, refer to the guidelines below before preparing your presentation.

  • YES to great technical talks
  • YES to fascinating theory
  • YES to innovative ideas
  • YES to sharing stories from the field
  • YES to open source and community projects
  • NO to sales pitches disguised as presentations
  • NO to hiring announcements during or after talks
  • NO to swag and goodies in the auditorium
  • NO to presenter branding on stage
  • ALWAYS follow the HasGeek Code of Conduct

Separating editorial content from sponsorship is a hallmark of HasGeek conferences and something that our community appreciates.
If you are hoping to promote your product, reach out to developers, or to hire talent from our audience, we’d be happy to connect you to our sales and sponsorship team who can offer you suggestions in adherence to our conference editorial policies.

No one submits the perfect proposal in the first instance. We therefore encourage you to:

  • Submit your proposal early so that we have more time to iterate if the proposal has potential.
  • Talk to us on our community Slack channel: https://friends.hasgeek.com if you want to discuss an idea for your proposal, and need help / advice on how to structure it.
  • Our editorial team also helps potential speakers in honing their speaking skills, fine tuning and rehearsing content at least twice - before the main conference - and sharpening the focus of talks.

How to submit a proposal?

The following guidelines will help you in submitting a proposal:

  1. Focus on why, not how. Explain to participants why you made a business or engineering decision, or why you chose a particular approach to solving your problem.
  2. Share as much detail as possible about how you solved the problem. Glossing over details does not help participants grasp real insights.
  3. Focus on what participants from other domains can learn/abstract from your solution.
  4. We do not accept how-to talks unless they demonstrate latest technology. If you are demonstrating new tech, show enough to motivate participants to explore the technology later.
  5. Content that can be read off the internet does not interest us. Our participants are keen to listen to use cases and experience stories that will help them in their practice.

To summarize, we do not accept talks that gloss over details or try to deliver high-level knowledge without covering depth. Talks have to be backed with real insights and experiences for the content to be useful.

Passes and honorarium for selected speakers:

Selected speakers get a pass to the conference. We also pay an honorarium of Rs. 5,000 to each speaker, at the end of the talk as token of gratitude for taking the time to prepare and speak at the conference.
We do not provide free passes for speakers’ colleagues and spouses.

Travel grants for outstation speakers:

Limited travel grants are available for international and domestic speakers. We evaluate each case on its merits, giving preference to women, people of non-binary gender, and Africans. If you require a grant, request it when you submit your proposal in the field where you add your location. 50p is funded through ticket purchases and sponsorships; travel grant budgets vary.

Credit Rating Transistion using Financial & Text Analytics

Submitted Dec 2, 2017

The credit rating of financial instruments is one of the factors that play a significant role while making investment decisions. Credit rating companies provide information about the credit stability/ transitions (deterioration/ up gradation) of the debt instruments using financial parameters, industry parameters, and external environment at quarterly intervals. In the present scenario, investment managers have to wait for quite some time to know about the credit rating stability/ transition. We propose that incorporating the market news available from different sources in almost real time along with the usual financial parameters should be able to predict the rating stability/ transition well in advance. The present work focus on incorporating sentiment scores extracted from various news sources like new aggregators like Bloomberg, Reuters, Company Web sites, Blogs etc. Depending upon the source of news a weight will be given taking into consideration trust worthiness of the source, Location of the Company information in the body of the news, Frequency of appearance. Using deep learning weights are assigned to each source. A Composite Sentiment score is computed as weighed average of the various individual news sources. This composite score is additional Input along with other financial parameters about eleven to survival analysis which in turn will forecast credit events. Our results show that Return on Capital Employed ROCE and Interest cover ratio along with sentiment scores are the best predictor variables to predict the rating stability/ transition. We tested our methodology on about three hundred companies. Most of them are from mining & textile segment as majority of downgrades and rating transitions have happened in those sectors. Back testing results show that proposed model very well predicts the credit rating stability/ transition. Without using the sentiment score the prediction accuracy of a transition was about 45% on hold out Samples (About 30 of 300) and with Financial and sentiment score it went up to about 70%. This work will be very helpful from the regulatory point of view also as one has to compute the Future value of Loan portfolio ie Credit Risk VAR. This method computes the Credit Risk VAR much accurately compared to existing methods of Credit Risk Computation.
Other outcome of this work is to predict crossover of rating from a given threshold. As an example the current rating may be Baa . After what point in time it will cross over to Ba. This is different from what transition Matrix gives. It gives for a given duration say a Year what is probability of change where as our method can tell when the change will take place it need not be at year intervals.

We have filed a provincial patent for this work.
