Learning Quantized Continuous Controllers for Integer Hardware
Researchers have developed new methods for creating efficient reinforcement learning controllers that can run on low-power hardware. One approach, "Learning Quantized Continuous Controllers," uses quantization-aware training to create policies that require only 2-3 bits per weight and activation, achieving microsecond inference times and microjoule energy consumption on FPGAs. Another method, "Differentiable Weightless Controllers," learns logic circuits that compile into FPGA-compatible circuits with single-clock-cycle latency and nanojoule energy costs, while maintaining competitive performance with standard deep policies and offering interpretable connectivity.
