Argmin for finding maximums

gamma_t = argmin_{gamma in |R} || r_{t-1} - x_{j_t} gamma ||. 3: * Set new residual r_t = r_{t-1} - x_{j_t} gamma_t if (||r_t|| = 0) stop. NOTES: - can add ...

You can use these indices to index into an array, and get the matching elements. Oct 27, 2020 ... So actually I managed to get hold of my lecturer to explain the argmax to argmin conversion.

This bitarray tells whether the index should be considered or not. ˆx = arg min x. [ky − Φxk2. 2 + λkxk0]. Wonderful result: can optimize `1 regularized least squares instead. ˆx = arg min x.
