Hi @chenbolinstudent, The data loading functions are compatible with the original release of the SALICON dataset. Which dataset are you using? |
I use the SALICON |
my configure is cuda9,python2.7,keras=1.1.0,theano=1.0.3,it that any configure require?thanks |
I do not know the function of ["I"] in the scipy |
The ["I"] is not a function of SciPy. For the original release of the SALICON dataset, authors provided matlab files with the fixation map for each image and the ["I"] is an attribute of those matlab files. |
can you give me the source of the original release of the SALICON dataset?thanks |
At the end of this page, you can find matlab files and saliency maps of the original release (i.e. the previous one) of the SALICON. |
thank you very much |
however,when I use the release salicon, i meet the same problem: |
@chenbolinstudent Hi! Following this modification, you can avoid this problem. While for me, my loss started from about 180 and suddenly jumped to nan (seems it will never back). @marcellacornia Could you give us an intro about how to train correctly? |
@eleboss Hi! I'm also experiencing a sudden drop to nan for loss. Did you figure out anything? |
@plin24 |
@eleboss @plin24 Hi! Thanks for downloading our code and sorry for the delay. In our experiments, we did not notice the same behavior during training and it's difficult to understand what caused the problem. It could be helpful to understand if a specific metric drops to nan. Note that our model is trained by using a combination of three different saliency evaluation metrics (i.e. KL-Divergence, Normalized Scanpath Saliency, and Linear Correlation Coefficient). Could you please try to train the network by using a single metric at a time as loss function? However, if you are interested, I have released the weights of our model (the ResNet version) also on the new release of the SALICON dataset. You can find them in the Pretrained Models Section of the README. |

please help me,thanks
