<p>GRBM-196-196s were trained on the whitened natural image data set using CD-10, PCD-10, and PT-10 with 10 linearly distributed inverse temperatures. The learning curves are averaged over 10 trials. The gradient was restricted to one hundredth of the maximal data norm (0.48) and the learning rate for the variance parameter was set 100 times smaller than for the other parameters.</p
