Abstract: Embodiments are provided herein for providing biometrics-based music recommendations to users. The biometric-based music recommendations take into account the changing music preferences of users from time to time as their biometrics change, such as due to users wellness states, being in different moods, engagement in different activities, and/or entering different environments. The schemes herein are implemented on user devices equipped or coupled to wearable devices capable of collecting biometrics data from users, such as heart rate, perspiration, and skin temperature data. The biometrics data of a user are collected and then processed into biometrics information. The biometrics information is then classified into a current wellness state of the user. A music recommendation is then provided to the user according to the biometrics information and the current wellness state of the user.

Abstract: The computational complexity of MCS adaptation for linear and non-linear MU-MIMO can be reduced by avoiding QR decomposition during subsequent stages of MCS adaptation. For instance, QR decomposition can be avoided in later stages of MCS adaptation by computing an instant upper right triangular matrix (R1) directly from an earlier upper right triangular matrix (R) and an earlier unitary matrix (U), which were obtained during a previous stage of MCS adaptation. As such, the instant upper right triangular matrix (R1) is obtained without performing QR decomposition on an instant Hermitian matrix (H1H), thereby allowing MCS adaptation to be performed for the new user group with less complexity. Additionally, computational complexity of MCS adaptation for linear MU-MIMO can be further reduced by avoiding matrix inversion during subsequent stages of MCS adaptation.
