| 5 | 1 | Federico Vera | # What to do with the Data |
| 6 | Now that you have successfully trained your `MLP` you might want to integrate it with other things, or whatever. |
||
| 7 | ## Evaluating from Java |
||
| 8 | 4 | Federico Vera | First of all you'll need to grab a copy of [`libai`](https://redmine.riddler.com.ar/projects/libai/roadmap) and add it to your classpath. |
| 9 | 1 | Federico Vera | |
| 10 | Then here's a sample code that can be used as a guide: |
||
| 11 | ~~~Java |
||
| 12 | import libai.nn.supervised.MLP; |
||
| 13 | import libai.common.Matrix; |
||
| 14 | |||
| 15 | ... |
||
| 16 | //The rest of your code |
||
| 17 | ... |
||
| 18 | |||
| 19 | public double f(double x) { |
||
| 20 | MLP mlp = MLP.open("weights.dat"); //<- the weights you want to use |
||
| 21 | Matrix m = new Matrix(1, 1); //<- we only use single neuron inputs |
||
| 22 | m.position(0, 0, x); //<- set the value in the matrix |
||
| 23 | return mlp.simulate(m).position(0, 0); //<- we only use single neuron output |
||
| 24 | } |
||
| 25 | ~~~ |
||
| 26 | |||
| 27 | ## Evaluating from CLI |
||
| 28 | ``` |
||
| 29 | $ java -jar mrft-VERSION.jar FILENAME VALUES |
||
| 30 | ``` |
||
| 31 | So for instance if you train the MLP with `cos(x)`, it should output: |
||
| 32 | ``` |
||
| 33 | 2 | Federico Vera | $ java -jar mrft-VERSION.jar weights.dat 0 1.0 |
| 34 | 1 | Federico Vera | ``` |
| 35 | You can also use the `-csv` or `-tsv` flags, so the output will be: |
||
| 36 | ``` |
||
| 37 | 2 | Federico Vera | $ java -jar mrft-VERSION.jar weights.dat -csv 0 0.0, 1.0 |
| 38 | 1 | Federico Vera | ``` |
| 39 | The output will always be via `sdt::out` so you can use something like `tee` to create a file |
||
| 40 | ``` |
||
| 41 | $ java -jar mrft-VERSION.jar -csv FILENAME VALUES | tee OUT.csv |
||
| 42 | ``` |
||
| 43 | |||
| 44 | ## GNU Octave |
||
| 45 | The current version of `libai` supports exporting matrices as `Octave-Level-1` binary matrices, but it still doesn't do that for `MLP`, so if someone actually want's to collaborate with some code, or wait a bit till I have some spare time. |
||
| 46 | 3 | Federico Vera | |
| 47 | ### Exporting to Octave format |
||
| 48 | ``` |
||
| 49 | $ java -jar mrft-VERSION.jar -octave weights.dat |
||
| 50 | ``` |
