Reference information for obtaining the Ultra96 board to use for this contest

・Subjected board for this contest is Ultra96-V2.
・Regarding method to obtain: There are two ways to obtain it.

1. Provided from this contest
- Although limited in number, the Ultra96 board will be provided after review for the contest participants. For those of you who wish to be provided, please apply through the "application form for board offer document review".
- Provided board includes an AC adapter, power conversion cable, and JTAG board.

2. Obtain from the Avnet website
- You can purchase from here.
- We recommend you to purchase the following related parts along the purchasing of the board.
JTAG board for Ultra96: It is necessary to connect the UART (serial) consol.
・Avnet recommended AC adapter, power conversion cable
 - Power supply
 - Conversion connector

Regarding the errata of Ultra96 board
The errata from Avnet is published the following site.

The errata particularly has the following known issues:
・Reboot issue of Ultra96-V2
 - Ultra96-V2 When the load of the PL part goes up high, MPSoC reboots.
 - Ultra96-V2 It is posted on the errata reporting page.
This is caused by the reset operation in MPSoC that was triggered by the PowerGood signal's drop when a specific threshold is exceeded while the IC called PMIC is monitoring the Vccint voltage.
- There is no margin for this threshold setting in the current V2 board, and a reset is applied when a set threshold is exceeded due to increase in current consumption of the PL section.
- The limit is 3A for the current ULtra96v2.

・The limit of this errata can be relieved to about 5A by revising the board and changing the setting of PMIC. A complete set of countermeasure procedures prepared by Avnet can be downloaded from below.
 20191114_Ultra96-V2 PMIC update (This can be obtained by the data tab on this website)
 Infinion that is required for the measures of this issue.
 The sales information of USB005 writing cable is as follows.

・We plan to provide this revised board for the board offered from this contest.

Evaluation method
[Precision] Evaluated by evaluation function "MAP@loU=0.75".
[Processing performance (fps)] Average inference time per sheet
[Area] Composed Report

Decision method of winners
1) Applicants whose Precision evaluation (final evaluation) of the predictive results posted during the contest period meet the Precision criteria 0.15 can be candidates for winners.(You can download a sample of the trained network based on Tiny Yolo v3, which is the basis for setting the accuracy standard, from the data page)
*The information of the precision criteria based on the original Tiny Yolo's network will be provided (provisional precision values) by the beginning of December, and the final required precision will be confirmed by the end of the year.
*The precision can be checked by using the submitting function of this website even during the contest, and evaluation after the contest ends (final evaluation) is adopted for the precision evaluation.

Evaluation until the final day of the contest (provisional evaluation) is performed by a part of the evaluation data set, and evaluation after the contest (final evaluation) is performed by the remaining part of the evaluation data set.

The leaderboard automatically switches to the final evaluation at the end of the contest. For this reason, rankings may vary greatly between during and after the event.

2) Among the winning candidates who meet the precision criteria and submit (application form has been set up at the bottom of the data page) a set of final results (including processing performance (average inference time per sheet) and the information of the FPGA implementation area) by the end of the contest (submission deadline), the top five people with the highest processing performance (plus those whose reports are worthy of attention) will be invited to the Review Committee.
The section where the processing time should be measured is "the time from performing inference processing on the image data already loaded on the memory, and then converting it to information equivalent to JSON such as dict".

3) The winners (best performance award and special award) are determined based on the processing performance, the content of the demo each brought in, the points of ingenuity (refer to this section for the area information) at the Review Committee.

Evaluation function of Precision
・The evaluation function MAP @ IoU = 0.75 will be used.
・An evaluation value between 0 and 1 will be assigned. The higher the accuracy, the higher the value will be.
・Please refer to the evaluation function that can be downloaded on the data page

Details of Evaluation function of Precision
1.For test images, if the IoU for the overlap of ground truth and prediction areas is 0.75 or greater, area detection is considered to have been successful.
2.For test images, average precision (AP) will calculated in each prediction category for objects in each detection area.
3.For each test image, mean average precision (MAP) calculation will be carried out for all eligible prediction categories based on step 2 results.
4.MAP, as calculated in step 3, will be calculated for all test images.
