After 48 hours, I still waiting for a reply from the team.

Hope to hear from @ola_supports te soon.

[Ola Support @ola_supports]

@MayankLal7 We are working on getting a resolution and will get in touch with you soon. Your patience is appreciated in the interim.

[Mayank Lal @MayankLal7]

@ola_supports Thanks for the quick response. I have shared my details on DM. Hope it is resolved at the earliest. Also, it would be great if you can share Incident Ticket Number with me for transperency and tracking. Hoping for your support and understanding.

With time, @Olacabs have become my preferred app to book cabs. But today was an horrendous experience.

Firstly, the driver added extra fees for parking and state tax, which were not part of the original fare. He was disrespectful and angry when I challenged him.

Raising this issue here so that other Ola Customers be aware of such tactics used by Ola Drivers and see how #Ola responds to Customer Grievances.

Great explainer video about the Multiple Comparisons Problem that helps one to develop an intuitive understanding of the mathematical concepts related to Data Dredging or p-hacking.

Great tutorial by @brodriguesco on building serverless dashboards with #R, #crosstalk, and #htmlwidgets.

Primary benefit of serverless dashboards is that one can share results in an easy and rapid manner with end-users.

#30daysofml with @kaggle was absolute fun.

During these 30 days, I got an opportunity to learn and implement my understandings of topics ranging from the basics of Python to advanced ML techniques like Model Blending & Stacking.

This was the best blend of learning styles.

[Mayank Lal @MayankLal7]

New things that I learned and want to explore more:

- Target Encoding
- Model Blending and Stacking
- Pipelines
- AutoML
- Other ensemble models like LightGBM, Tensorflow, CatBoost, etc.

If there are any good tutorials on the same, kindly do share.

Preferably with an example in R.

[Mayank Lal @MayankLal7]

Most of the tutorials and books related to ARIMAX are just limited to one predictor. Even the OG Prof. Hyndman's book.

There is no guide on how to deal with multiple predictors and handling their seasonality and forecasting their values in an ARIMAX model.
