Object recognition by sparse random binary data lookup. Complementary code for this article
Performing single-shot Fashion-MNIST objects recognition by lookup over the most different sparse input bit sets of the training data (out of 28⋅28⋅8 = 6272 bits per training sample)
Work continued in this repository by switching to smaller 'punched card' bit sizes and adjacency matrices instead of sparse bit vector operations
The same algorithm applied to the QMNIST dataset is here
Results and program output are from this code version
- Recognition accuracy on a best 512 bit punched card is 41.42%
- Punched cards per specific label in most cases works better or equal than one (global top) punched card
- Starting from bit length 32 there are cases when all the inputs per specific label of the punched card are unique
- Test set accuracy increasing almost linearly with the doubling of the punched card bit length up to 128. But after that no significant improvements (due to the lack of punched cards ranking algorithm except max distinct inputs count)
- How to rank the punched cards when all the inputs per specific label are unique?
- How to make sure that chosen punched card is the best? Need to evaluate all of them?
- It's possible to calculate the entropy of the inputs of the specific punched card per label (to rank them)
- Try calculate the relative importance of each bit of the punched card input (like attention mechanism). Use this metric for ranking.
- Build hierarchy of punched cards to perform lookup over the multiple punched card results instead of simple max. Interesting for small bit lengths but multiple punched cards.
- Prefer processing with less active bits on all stages (since electrical pulses in a brain requires energy)
- Encode (or map) the binary input somehow to have/keep the 2% sparsity (like in a brain)
