Researchers have developed a method to optimize reservoir computers by aligning their nonlinearity with that of the input data. This approach, tested using a generalized fractional Halvorsen system, found that matching the smallest nonlinearity in the data maximizes predictive performance. The study proposes a practical method for estimating unknown time series nonlinearity by adjusting reservoir exponents and demonstrates its effectiveness on synthetic and real-world financial data. The findings are transferable to classical reservoir computing, offering performance gains in resource-constrained environments. AI
