Aplicado ao mundo real.

Exibiu altas perfomances em todas tarefas propostas.

Melhores performances sobre o baseline.

Baixo consumo de memória.

Vantagens

Page 6: Large-Scale Music Annotation and Retrieval: Learning to Rank in Joint Semantic Spaces

Encontrar os melhores parâmetros.

Minimizar a função:

Utilizou AUC Margin Ranking Loss e WARP Loss.

Fase de treinamento

Page 7: Large-Scale Music Annotation and Retrieval: Learning to Rank in Joint Semantic Spaces

Como utilizado stochastic gradient descent cada modelo aprende parametros com valores um pouco diferentes.

A média das funções:

Algoritmo

Page 9: Large-Scale Music Annotation and Retrieval: Learning to Rank in Joint Semantic Spaces

Meta dados - Cold start se utilizar somente filtragem colaborativa.

Baseada em conteúdo: MFCCs (Mel Frequency Cepstral Coefficient) e (SAI) Stabilized Auditory Image.

Features

TagATune – Tem um conjunto de clips contendo 30 segundos. Tem anotações associadas. Coletado por usuários em forma de jogo.

TagATune usado no MIREX 2009 desafio de classificação de tags.

Para comparação utilizado mesmas tags e bases de treino.
