Corrections to “Attention Relational Network for Skeleton-Based Group Activity Recognition”

In the above article
[1]
, the dataset mentioned as Hockey Penalty Dataset (HPD) is not what described in
[2]
and
[3]
and instead it is referred to as YMJA dataset. HPD was never made available to the public by the authors of
[2]
and
[3]
, and the dataset that we accessed, while it was briefly available online, and used in
[1]
is different and is called YMJA. Therefore, the corresponding dataset description in
[1]
needs to be corrected. We now understand that the YMJA dataset was never officially released or supported by the authors of
[2]
and
[3]
. Note that
[2]
and
[3]
are references 21 and 49, respectively, in
[1]
.
