Target $I$ for the Gated-LSTM baseline

[lionminhu]

Hello, I have been trying to implement the Gated-LSTM baseline according to the descriptions in the RoomNav paper (link), but I am confused with the some of the notations.

From Section 5.2.2 (for Gated-LSTM):

The symbol $I$ is used to denote the target instruction. This same symbol was used in Section 5.1.2 (for Gated-CNN) to denote the target instruction prior to conversion to an embedding vector $y$:

So if we were to follow the same notation as in Section 5.1.2, we would have to feed the one-hot vector $I$ (and not the embedding vector) as input to the gated fusion module and the LSTM for the Gated-LSTM.

However, the Figure 2 seems to imply that it is in fact the embedding vector that is fed into the gated fusion and the LSTM:

Could you clarify whether the target $I$ for Gated-LSTM baseline is meant to be the one-hot vector or the embedding vector?

Thank you in advance.

@lionminhu Hi, where did you get the SUNCG data to install this library?

[lionminhu]

Previously (as in minosworld/minos#94), we were able to request the authors for the SUNCG dataset.
Due to legal issues (citation), however, the download links and the forms have all been removed (c727331).
I do not think the dataset is going to be available again in a while, if at all.

Relevant: #57, minosworld/minos#159

Yes, can you share the link for downloading the data or do you know how to use other datasets to fix this issue?

Unfortunately, I am not aware of any download links that work anymore.
My knowledge is possibly outdated, but if house dataset/environment is what you need, you may also want to consider GibsonEnv with Matterport3D dataset.
