Enrico Picco, Piotr Antonik, Serge Massar
This research successfully applies a photonic Reservoir Computer to Human Action Recognition, achieving high classification accuracy and processing speed by introducing a novel “Timesteps Of Interest” training method. The system obtained 90.83% accuracy on the KTH dataset at an experimental processing rate of 160 frames per second.
Key insights
- Simple photonic RC architectures can effectively handle complex temporal classification tasks, demonstrating performance comparable to or exceeding prior RC attempts while offering high speed.
- The TOI training method enhances RC capabilities by integrating state information from different time points in a sequence, effectively extending memory without increasing reservoir complexity.
- Optimal system performance depends on careful hyperparameter tuning, including reservoir size, number of TOIs, and the level of dimensionality reduction, as guided by Bayesian optimization.
