ICA basis functions trained on simulated sounds (A) Binaural basis functions a^g_i. Left and right ear parts are dissimilar. (B) Monaural basis functions a^k_i. Left and right ear parts are highly similar. (C) Explanation of the representation. Each stimulus can be decomposed into a linear combination of monaural basis functions (multiplied by their coefficients s^c_i) and binaural ones multiplied by coefficients s^g_i.
