Meeting 2: Encoding classical data in Lau et al.

During meeting 2 there was some confusion when interpreting Eq. (1) in the paper Quantum machine learning over infinite dimensions. More precisely, we do not have clear what does the quantity d represents. In the text the definition that appears is

where d is the number of basis state in each mode

We do not understand, however, what this number is, since a CV system (as far as our understanding reaches) has an infinite number of basis states. Any insights are appreciated

Installation problems with Doom environment

Hi,

I tried to install gym_pull (needed to set up the doom environment) on my mac but it failed. It seems that some dependencies are missing. I also tried the second method by installing ppaquette-gym-doom but I get the following error:

Regards,

Alexandre

Training Boltzmann machines in Wiebe et. al

In appendix E, section 5 of Quantum Deep Learning, the authors write:

[...] our quantum algorithms [...] can therefore efficiently train full Boltzmann machines given that the mean-field approximation to the Gibbs state has only polynomially small overlap with the true Gibbs state.

However, by reading the rest of the article one is lead to the idea that using mean-field theory is a good enough state (better than a uniform state) to be used as a prior in the network.

Does this phrase therefore have a typo or am I missing something?

Implementation of HHL is not perfect

As a quick summary, some of us are still doing the homework of meeting 7, which consists on implementing a quantum support vector machine following this paper. The implementation needs of a means of inverting matrices, and a quantum way is described in this paper here. We have implemented the algorithm in this last paper, but the results are not quite what we expected. After working quite a bit on it, I have realized that one of the assumptions in the paper is not (even approximately) always satisfied. The assumption in question appears after the third equation of page 3, and is that phase estimation is perfect. This should of course not to be expected to hold perfectly, but it turns out that usually there is not one, but a few of states whose $|\alpha_{k|j}|$ are of comparable size (and much closer to 1 than the rest). This makes the result of dropping out the $|\lambda\rangle$ register a mixed state, instead of a pure one. The way I have thought of circumventing this problem is doing a projection on to the $|\lambda\rangle$ of greatest amplitude before dropping the register. That will undoubtedly bring errors, but up to now I have not come up with other means of obtaining a "reasonable output" from the matrix inversion algorithm.

Transverse field in Amin et al.

When reading this week's quantum paper, I came across something I do not quite understand. In Eq. (16) they define their truly quantum Boltzmann machine Hamiltonian, which has home transverse field, and then they argue that there is one term in the derivative of the error function Eq. (18) that cannot be estimated using sampling. My question is then: does this mean that this QBM would not suppose any improvement over a QBM without the transverse field? It seems like with exact diagonalization they get improvements, so would this be more like some kind of experimental limitation?

Negative phase in Boltzmann machine

I was trying to train a Boltzmann machine in the way they do in Benedettis et al. paper (arXiv:1609.02542). I am wondering how to calculate equations (9) and (10) correctly. My problem comes when calculating the ensemble average with respect to the distribution P(z) (the negative phase).
Does this distribution evolve at the same rate as the coupling parameters J and h change through equations (7) and (8)? In order words, each time I update the couplings, I should apply this changes to the model lattice and calculate a new spin distribution?

Pretrain networks with RBM

According to the question today:
Why is pretraining with RBM necessary and why don't we have to do that anymore today? I have found the following paper:

http://www.jmlr.org/papers/volume11/erhan10a/erhan10a.pdf

Let's use this 'Issue' to figure this out and discuss a bit.
