Zusammenfassung

Viele ML-Methoden verwenden das Prinzip der ERM (siehe Kap. 4), um eine Hypothese aus einem Hypothesenraum zu lernen, indem sie den durchschnittlichen Verlust (Trainingsfehler) auf einer Menge von beschrifteten Datenpunkten (Trainingsset) minimieren.

Notes

  1. 1.

    Ein wichtiges Beispiel für eine solche strukturelle Ähnlichkeit im Falle von linearen Prädiktoren \(h^{(t)}(\mathbf{x}) =\big (\mathbf{w}^{(t)} \big )^{T} \mathbf{x}\) liegt vor, wenn die Gewichtsvektoren \(\mathbf{w}^{(T)}\) eine kleine gemeinsame Unterstützung \(\bigcup _{t=1,\ldots ,T} {{\,\mathrm{supp}\,}}( w^{(t)} )\) haben. Die Forderung, dass die Gewichtsvektoren eine kleine gemeinsame Unterstützung haben, entspricht der Forderung, dass der gestapelte Vektor \(\widetilde{\mathbf{w}}=\big (\mathbf{w}^{(1)},\ldots ,\mathbf{w}^{(T)} \big ) \) block- (gruppen-) spärlich ist [12].
