Dear Moderator,

My team has already downloaded two zip files for validation data
and noticed that the following data are exactly the same.

Specimen T6(training)
Specimen T8(validation)

We appreciate if you give us some comments and further advices

Thanks,

Dear TPRML,

We are investigating this issue and will provide an update ASAP.

Any updates for this question? We found the same issue. T6 has the exact same signal as T8.

The data challenge committee has identified the source of this problem. The original T6 training data is erroneous and happens to include 3 sets of signals from T8 validation data (cycle numbers 40000, 50000, and 70000). Additionally, The T6 description file is not representative of either T6 or T8 crack length data. Note: T8 validation data is correct.

Our corrective action plan is as follows:

1) The correct T6 training data will be posted within the next 24 hours.

2) The result submission period will be extended from 21 July to 31 July, 2019 (11:59:59 pm PDT). This will allow teams an opportunity to update their models (if desired) based on the corrected T6 training data.

3) All teams will have access to the full T7 and T8 validation data (excluding crack length data). Note: many teams have already accessed the validation data.

4) All existing team result submissions will be cleared, and teams will have the opportunity to submit new predictions via an updated results submission website. The updated results submission website will be available no later than 19 July 2019 (11:59:59 pm PDT).

Please note, other relevant dates will be updated as follows:
– Preliminary Winners Announced = 4 August, 2019
– Winners Announced = 18 August, 2019
