Description (last modified by )
In several recent papers, David Roe, Tristan Vaccon and I explain that lattices allow a sharp track of precision: if f is a function we want to evaluate and x is an input given with some uncertainty modeled by a lattice H, then the uncertainty on the output f(x) is exactly df_x(H).
For much more details, I refer to my lecture notes http://xavier.toonywood.org/papers/publis/coursepadic.pdf
The aim of this ticket is to propose a rough implementation of these ideas.
You can play with the latest version of this by clicking on launch binder here.
Below is a small demo (extracted from the doctest).
Below is a small demo of the features by this model of precision: sage: R = ZpLP(3, print_mode='terse') sage: x = R(1,10) Of course, when we multiply by 3, we gain one digit of absolute precision: sage: 3*x 3 + O(3^11) The lattice precision machinery sees this even if we decompose the computation into several steps: sage: y = x+x sage: y 2 + O(3^10) sage: x + y 3 + O(3^11) The same works for the multiplication: sage: z = x^2 sage: z 1 + O(3^10) sage: x*z 1 + O(3^11) This comes more funny when we are working with elements given at different precisions: sage: R = ZpLP(2, print_mode='terse') sage: x = R(1,10) sage: y = R(1,5) sage: z = x+y; z 2 + O(2^5) sage: t = xy; t 0 + O(2^5) sage: z+t # observe that z+t = 2*x 2 + O(2^11) sage: zt # observe that zt = 2*y 2 + O(2^6) sage: x = R(28888,15) sage: y = R(204,10) sage: z = x/y; z 242 + O(2^9) sage: z*y # which is x 28888 + O(2^15) The SOMOS sequence is the sequence defined by the recurrence: ..MATH:: u_n = rac {u_{n1} u_{n3} + u_{n2}^2} {u_{n4}} It is known for its numerical instability. On the one hand, one can show that if the initial values are invertible in mathbb{Z}_p and known at precision O(p^N) then all the next terms of the SOMOS sequence will be known at the same precision as well. On the other hand, because of the division, when we unroll the recurrence, we loose a lot of precision. Observe: sage: R = Zp(2, 30, print_mode='terse') sage: a,b,c,d = R(1,15), R(1,15), R(1,15), R(3,15) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 4 + O(2^15) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 13 + O(2^15) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 55 + O(2^15) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 21975 + O(2^15) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 6639 + O(2^13) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 7186 + O(2^13) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 569 + O(2^13) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 253 + O(2^13) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 4149 + O(2^13) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 2899 + O(2^12) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 3072 + O(2^12) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 349 + O(2^12) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 619 + O(2^12) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 243 + O(2^12) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 3 + O(2^2) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 2 + O(2^2) If instead, we use the lattice precision, everything goes well: sage: R = ZpLP(2, 30, print_mode='terse') sage: a,b,c,d = R(1,15), R(1,15), R(1,15), R(3,15) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 4 + O(2^15) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 13 + O(2^15) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 55 + O(2^15) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 21975 + O(2^15) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 23023 + O(2^15) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 31762 + O(2^15) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 16953 + O(2^15) sage: a,b,c,d = b,c,d,(b*d+c*c)/a; print d 16637 + O(2^15) sage: for _ in range(100): ....: a,b,c,d = b,c,d,(b*d+c*c)/a sage: a 15519 + O(2^15) sage: b 32042 + O(2^15) sage: c 17769 + O(2^15) sage: d 20949 + O(2^15) BEHIND THE SCENE: The precision is global. It is encoded by a lattice in a huge vector space whose dimension is the number of elements having this parent. Concretely, this precision datum is an instance of the class "sage.rings.padic.lattice_precision.PrecisionLattice". It is attached to the parent and is created at the same time as the parent. (It is actually a bit more subtle because two different parents may share the same instance; this happens for instance for a padic ring and its field of fractions.) This precision datum is accessible through the method "precision()": sage: R = ZpLP(5, print_mode='terse') sage: prec = R.precision() sage: prec Precision Lattice on 0 object This instance knows about all elements of the parent, it is automatically updated when a new element (of this parent) is created: sage: x = R(3513,10) sage: prec Precision Lattice on 1 object sage: y = R(176,5) sage: prec Precision Lattice on 2 objects sage: z = R.random_element() sage: prec Precision Lattice on 3 objects The method "tracked_elements()" provides the list of all tracked elements: sage: prec.tracked_elements() [3513 + O(5^10), 176 + O(5^5), ...] Similarly, when a variable is collected by the garbage collector, the precision lattice is updated. Note however that the update might be delayed. We can force it with the method "del_elements()": sage: z = 0 sage: prec Precision Lattice on 3 objects sage: prec.del_elements() sage: prec Precision Lattice on 2 objects The method "precision_lattice()" returns (a matrix defining) the lattice that models the precision. Here we have: sage: prec.precision_lattice() [9765625 0] [ 0 3125] Observe that 5^10 = 9765625 and 5^5 = 3125. The above matrix then reflects the precision on x and y. Now, observe how the precision lattice changes while performing computations: sage: x, y = 3*x+2*y, 2*(xy) sage: prec.del_elements() sage: prec.precision_lattice() [ 3125 48825000] [ 0 48828125] The matrix we get is no longer diagonal, meaning that some digits of precision are diffused among the two new elements x and y. They nevertheless show up when we compute for instance x+y: sage: x 1516 + O(5^5) sage: y 424 + O(5^5) sage: x+y 17565 + O(5^11) It is these diffused digits of precision (which are tracked but do not appear on the printing) that allow to be always sharp on precision. PERFORMANCES: Each elementary operation requires significant manipulations on the lattice precision and then is costly. Precisely: * The creation of a new element has a cost O(n) when n is the number of tracked elements. * The destruction of one element has a cost O(m^2) when m is the distance between the destroyed element and the last one. Fortunately, it seems that m tends to be small in general (the dynamics of the list of tracked elements is rather close to that of a stack). It is nevertheless still possible to manipulate several hundred variables (e.g. squares matrices of size 5 or polynomials of degree 20 are accessible). The class "PrecisionLattice" provides several features for introspection (especially concerning timings). If enables, it maintains an history of all actions and stores the wall time of each of them: sage: R = ZpLP(3) sage: prec = R.precision() sage: prec.history_enable() sage: M = random_matrix(R, 5) sage: d = M.determinant() sage: print prec.history() # somewhat random  0.004212s oooooooooooooooooooooooooooooooooooo 0.000003s oooooooooooooooooooooooooooooooooo~~ 0.000010s oooooooooooooooooooooooooooooooooo 0.001560s ooooooooooooooooooooooooooooooooooooooooo 0.000004s ooooooooooooooooooooooooooooo~oooo~oooo~o 0.002168s oooooooooooooooooooooooooooooooooooooo 0.001787s ooooooooooooooooooooooooooooooooooooooooo 0.000004s oooooooooooooooooooooooooooooooooooooo~~o 0.000198s ooooooooooooooooooooooooooooooooooooooo 0.001152s ooooooooooooooooooooooooooooooooooooooooo 0.000005s ooooooooooooooooooooooooooooooooo~oooo~~o 0.000853s oooooooooooooooooooooooooooooooooooooo 0.000610s ooooooooooooooooooooooooooooooooooooooo ... 0.003879s ooooooooooooooooooooooooooooooooooooooooooooooooooooooooo 0.000006s oooooooooooooooooooooooooooooooooooooooooooooooooooo~~~~~ 0.000036s oooooooooooooooooooooooooooooooooooooooooooooooooooo 0.006737s oooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo 0.000005s oooooooooooooooooooooooooooooooooooooooooooooooooooo~~~~~ooooo 0.002637s ooooooooooooooooooooooooooooooooooooooooooooooooooooooooo 0.007118s ooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo 0.000008s oooooooooooooooooooooooooooooooooooooooooooooooooooo~~~~o~~~~oooo 0.003504s ooooooooooooooooooooooooooooooooooooooooooooooooooooooooo 0.005371s ooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo 0.000006s ooooooooooooooooooooooooooooooooooooooooooooooooooooo~~~o~~~ooo 0.001858s ooooooooooooooooooooooooooooooooooooooooooooooooooooooooo 0.003584s ooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo 0.000004s oooooooooooooooooooooooooooooooooooooooooooooooooooooo~~o~~oo 0.000801s ooooooooooooooooooooooooooooooooooooooooooooooooooooooooo 0.001916s ooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo 0.000022s ooooooooooooooooooooooooooooo~~~~~~~~~~~~~~~~~~~~~~oooo~o~o 0.014705s ooooooooooooooooooooooooooooooooooo 0.001292s ooooooooooooooooooooooooooooooooooooo 0.000002s ooooooooooooooooooooooooooooooooooo~o The symbol o symbolized a tracked element.

 Type changed from task to enhancement
I've worked more on my implementation and, at least, it seems now to be usable.
It still requires a lot of work (convert to Cython, write templates, rewrite completely the class pRational
which is a hack, etc). I however post it because I think that some people might have fun playing with it and discovering what lattice precision can do. Enjoy :)

Replying to saraedum:
Do you document somewhere why this does not follow the usual linkage pattern used elsewhere in the padics code?
I think the main answer is that it just hasn't been switched to the linkage pattern, but it should be. The pRational will take some work to make this happen. I'll be busy in the next few weeks working on an ANTS paper, but we can talk about this in Rennes. In the mean time, I think if you want to push the code to github/gitlab that should be fine.

The reason is that (1) coefficient
returns a multivariate polynomial and (2) if P is a multivariate polynomial, list(P)
contains some multivariate polynomials in it as well.

. There are also more convenient commands for this, I can show you later.)

IMHO, not a good idea at all to merge the "binder" branch with this ticket. The patchbots will not longer look at it, because it is now unsafe.
comment:47 Changed 11 months ago by
I agree, I merged them accidentally. I will remove them later. For now, the ticket is not quite ready for review; I just wanted to check whether the patchbot is happy with my changes.

As I said, as long as the branch is messed up, patchbots will refuse to run..
comment:50 Changed 11 months ago by
@chapoton: Thanks for clarifying how the patchbots work here. We'll take the binder out at the end and squash the other commits. We use the CI integration because we are developing this on GitLab? and also because we wanted to see a sandbox environment to play with this.
@caruso: I'll run doctests on GitLab?, they should be available in a couple of hours.

I fixed some failures but I think that this ticket is not responsible for the doctest failure in interacts/test_jupyter.rst
. What should I do with it?

I am not sure what this is about. I don't think that's a problem coming from the changes here, so we should not fix it here.

There are issues with python3 division in lattice_precision:
source ./local/bin/sageenv python Qnew ./local/bin/sageruntests src/sage/rings/padics
reports many failing doctests. This can be seen also when adding
from __future__ import division
in the file.
comment:67 Changed 9 months ago by
and you also introduced some "has_key", so please review #25280

Adding the line:
__truediv__ = __div__
in the defintion of the class pRational
resolves this issue. Is it the right way to fix this or should I do something else?

code from this ticket seems to trigger TimeOut

comment:70 Changed 8 months ago by
Thanks for pointing this out. I created a followup #25431.
comment:71 Changed 3 months ago by
The file padic_lattice_element.py
is now one of the last 3 files (see #26212) having more than 100 failing doctests in python3:
sage t long src/sage/rings/padics/padic_lattice_element.py # 167 doctests failed
It would be appreciated if the authors of this code could handle the task of making all this compatible with python3.
comment:72 Changed 3 months ago by
I'll take a look. I've opened #26576.
comment:73 Changed 3 months ago by
I'd be happy to contribute as well but I don't know so much about Python3 (which explains why this ticket has so many failures...)
In particular, what should I do if I want to run doctests with the python3 interpretor. Do I need to install a new copy of sage compiled with python3 or is there something more clever?
