❓ Frequently Asked Questions
What is a neural network in financial modeling?
A computational model that mimics brain-like processing to find patterns in financial data, using layers of interconnected units to learn relationships between inputs (prices, indicators) and outputs (predictions) from historical data.
What types of neural networks are commonly used in finance?
Feedforward networks for general predictions, recurrent networks (RNNs) and LSTMs for time-series data, and sometimes CNNs for extracting features from data representations such as heatmaps or structured inputs.
How do neural networks learn from historical data?
They are trained on past data to minimize prediction errors. During training, backpropagation computes gradients of the loss with respect to weights, and an optimizer updates weights to improve accuracy.
What are common risks or limitations when using neural networks for financial modeling?
Overfitting to past data, sensitivity to regime changes, data quality requirements, interpretability challenges, and non-stationary behavior; robust validation and risk controls are essential.
