Supports dynamic network architectures with removable neurons and synapses, plus six pre-built network types (LSTM, GRU, Perceptron) alongside layer-based and neuron-by-neuron composition. Implements the Instinct neuro-evolution algorithm with multi-threaded evolution and backpropagation claiming 5x+ performance gains over competitors. Runs identically in browser and Node.js environments for both supervised and unsupervised learning tasks.
