# FIM-Estimation
|
2 |
+
In a FIM-Estimation task, the input consists of
|
3 |
+
|
4 |
+
1. A dataset of the form $\mathcal{D}_ {train} = \{(\mathbf{\lambda}_ i, x_ i)\}_ {i=1}^{\left|\mathcal{D}\right|}$, where $\vlambda_ i$ is a point in the parameter space and $x_ i$ is a sample.
|
5 |
+
2. The structure of the samples $x_ i$. For example, if $x_ i\in\{0,1\}^n$ is a bitstring representing a measurement of a quantum system on a lattice with $n$ sites, then the said structure is the lattice and the correspondence between the bitstring bits and the lattice sites.
|
6 |
+
3. Optionally, additional information about the statistical manifold. This could involve, e.g., the symmetries of the system used to generate the statistical manifold.
|
7 |
+
|
8 |
+
The task is to estimate Fisher Information Metric as a matrix-valued function of parameter $\mathbf{\lambda}$.
|
9 |
+
|
10 |
+
We (TODO:plan to) present datasets corresponding to 6 statistical manifolds: `XXZ300_Z`, `FIL24`, etc.
|
11 |
+
The data is stored as follows:
|
12 |
+
`data/xxz300_z` contains the data for `XXZ300_Z` datasets. Within that directory, there are subdirectories of the form `seed_??` each containing a dataset describing the same statistical manifold, but generated using a different seed (e.g. `seed_05`). We have `seed_05/d_train.parquet`, which is the dataset as described in #1 above. `seed_05/d_test.parquet` is a hold-out dataset which should not be used in estimation of $\mathbf{\lambda}$ (not even for hyperparameter tuning).
|
13 |
+
`data/xxz300_z/meta.json` (TODO) represents the metadata (including information listed in #2 and #3 above)
|
14 |
+
`data/xxz300_z/fim_ground_truth.json` (TODO) represents the ground truth FIM.
|
15 |
+
|
16 |
+
An algorithm attempting to solve the FIM-Estimation task `XXZ300_Z(seed=05)` shall take `data/xxz300_z/seed_05/d_train.parquet` and `data/xxz300_z/meta.json` as inputs and produce FIM estimates to be compared with `data/xxz300_z/fim_ground_truth.json`.
