FaceSSD Fairness Indicators Example Colab

Visão geral

Nesta atividade, você usará Fairness Indicators para explorar as previsões FaceSSD no conjunto de dados Labeled Faces in the Wild . Os indicadores de imparcialidade são um conjunto de ferramentas desenvolvidas com base na Análise de modelo do TensorFlow que permitem a avaliação regular de métricas de imparcialidade em pipelines de produtos.

Sobre o conjunto de dados

Neste exercício, você trabalhará com o conjunto de dados de predição FaceSSD, aproximadamente 200 mil previsões de imagens diferentes e verdades fundamentais geradas pela API FaceSSD.

Sobre as ferramentas

A Análise de modelo do TensorFlow é uma biblioteca para avaliar modelos de aprendizado de máquina TensorFlow e não TensorFlow. Ele permite que os usuários avaliem seus modelos em grandes quantidades de dados de maneira distribuída, computando em gráfico e outras métricas sobre diferentes fatias de dados e visualizando em notebooks.

A validação de dados do TensorFlow é uma ferramenta que você pode usar para analisar seus dados. Você pode usá-lo para encontrar problemas potenciais em seus dados, como valores ausentes e desequilíbrios de dados, que podem levar a disparidades de imparcialidade.

Com os indicadores de justiça , os usuários serão capazes de:

  • Avalie o desempenho do modelo, dividido em grupos definidos de usuários
  • Sinta-se confiante sobre os resultados com intervalos de confiança e avaliações em vários limites

Importando

Execute o código a seguir para instalar a biblioteca fairness_indicators. Este pacote contém as ferramentas que usaremos neste exercício. O Restart Runtime pode ser solicitado, mas não é necessário.

pip install -q fairness-indicators

Baixe e entenda os dados

O Labeled Faces in the Wild é um conjunto de dados de referência público para verificação de rosto, também conhecido como correspondência de pares. O LFW contém mais de 13.000 imagens de rostos coletadas da web.

Executamos previsões FaceSSD neste conjunto de dados para prever se um rosto está presente em uma determinada imagem. Neste Colab, dividiremos os dados de acordo com o gênero para observar se há diferenças significativas entre o desempenho do modelo para diferentes grupos de gênero.

Se houver mais de um rosto em uma imagem, o gênero será rotulado como "FALTA".

Hospedamos o conjunto de dados no Google Cloud Platform por conveniência. Execute o código a seguir para baixar os dados do GCP. Os dados levarão cerca de um minuto para baixar e analisar.

Renderizar indicadores de justiça

Renderize o widget Indicadores de imparcialidade com os resultados da avaliação exportados.

Abaixo, você verá gráficos de barras exibindo o desempenho de cada fatia dos dados nas métricas selecionadas. Você pode ajustar a fatia de comparação da linha de base, bem como o (s) limite (s) exibido (s) usando os menus suspensos na parte superior da visualização.

Uma métrica relevante para esse caso de uso é a taxa positiva verdadeira, também conhecida como recall. Use o seletor no lado esquerdo para escolher o gráfico para true_positive_rate. Esses valores métricos correspondem aos valores exibidos no cartão do modelo .

Para algumas fotos, o gênero é rotulado como jovem em vez de masculino ou feminino, se a pessoa na foto for muito jovem para ser anotada com precisão.
