Cannot converge when I switch cifar10 to caltec101 dataset about caffe-deepbinarycode

[kevinlin311tw]

Since caltech101 dataset has 101 object categories, you need to modify the softmax layer to 101 nodes.

Help me figure it out, thanks.
Below is the steps I followed to conduct my experiment.
A: I split caltec101 to two disjoint dataset:
1, train.txt with 7357 images
2, val.txt with 1788 images
then I pack them into leveldb by run create_imagenet.sh.
B: I train the net followed the step when I train on cifar10. I did not modified the training and caffe net param and use 48 bits as default

C: When I train the model, I noticed the log show as below. That was not I want like I finished training on cifar10 I got "Test net output #0: accuracy = 0.903437".

Solved. Thanks.

I got an accuracy of near 0.9 after I changed the softmax layer followed by your advice and conduct a new experiment.
