Typical deep learning models for object recognition have feedforward architectures including HMAX and CNN.This is a crude approximation of the visual pathway in the brain since there are abundant recurrent connections in the visual cortex. We show that adding recurrent connections to CNN improves its performance in object recognition.

There is a debate about whether low-level features or high-level features are more important for prediction eye fixations. Through experiments, we show that mid-level features and object-level features are indeed more effective for this task. We obtained state-of-the-art results on several benchmark datasets including Toronto, MIT, Kootstra and ASCMN at the time of submission.

There is a trend for incorporating more and more features for supervised learning of visual saliency on natural images. We find much redundancy among these features by showing that a small subset of features leads to excellent performance on several benchmark datasets. In addition, these features are robust across different datasets.

MATLAB codes

The close connection between the L1-norm support vector regression (SVR) and sparse coding (SC) is revealed and some typical algorithms are compared for linear regression. The results show that the SC algorithms outperform the L1-SVR algorithms in efficiency. The SC algorithms are then used to design RBF networks, which are more efficient than the well-known orthogonal least squares algorithm.

We show that a deep learning model with alternating sparse coding/ICA and local max pooling can learn higher-level features on images without labels. After training on a dataset with 1500 images, in which there were 150 unaligned faces, 6 units on the top layer became face detectors. This took a few hours on a laptop computer with 2 cores, in contrast to Google's 16,000 cores in a similar project.
