Is the Boltzmann machine the same as a Conditional Random Field? If so that should be mentioned somewhere!


[edit] The threshold

What is the importance of the threshold parameter? How is it set?

[edit] The Training Section

I have a problem understanding what is P+(Vα). P+ is the distribution of the states after the values for Vα are fixed. So P+(Vα) should be 1 for those fixed values and 0 for any other values to Vα.

Also, what does α iterate over in the summation for G?

[edit] The cost function

What is the cost function? What cost does it measure? How do we train the network if we have more than one input?
