Automatic Target Recognition using Fuzzy Neural Networks
In this implementation we have done comparative study of 2 kinds of neural networks for a multi class-classification task.
Data set used - MSTAR SAR DATA
The unreasonably superior capabilities of MAMs
MAMs have the capabilities of recalling images even on high erosion and dialtion, losses as great as almost 50% and can be recalled at 0% loss.
| Original Image | Eroded image | Reconstructed image |
|---|---|---|

You can see the code implementation in MAMs discussion.ipynb-
Constraints -
Generally we need lots of high quality data for neural nets to do a pretty good job on classification but what if you wanted to do classification on data that was -
- Highly noisy
- Very small in size (here around 1000 samples)
Exact details -
| MODEL | TRAIN | VALIDATION | TEST |
|---|---|---|---|
| MLP | 696 | 174 | 408 |
| DMN | 870 | - | 408 |
I was really skeptic of results this morphological model will get because I could never imagine it could perform this good given the constraints. So the results I got by running this dataset on DMN and an MLP are as follows -
| MODEL | TRAIN | TEST |
|---|---|---|
| MLP | 33% | 33% |
| DMN | 100% | 71.57% |
I am pretty sure this can be made better which will be done in my forthcoming work. Also fuzzyfication of MAMs would be my next job in order to make it noise tolerant. Please take a look at the MLP model.ipynb here and DCpretraining.m inside the DMN_SGD for DMN implementation.
