Visão geral
Fairness Indicators é um conjunto de ferramentas construídas em cima de TensorFlow Modelo de Análise (TFMA) que permitem a avaliação periódica das métricas de justiça em oleodutos de produtos. O TFMA é uma biblioteca para avaliar modelos de aprendizado de máquina TensorFlow e não TensorFlow. Ele permite que você avalie seus modelos em grandes quantidades de dados de maneira distribuída, calcule no gráfico e outras métricas em diferentes fatias de dados e visualize-as em notebooks.
Fairness Indicators é empacotado com TensorFlow Validação de dados (TFDV) ea Ferramenta What-Se . O uso de indicadores de imparcialidade permite que você:
- Avalie o desempenho do modelo, dividido em grupos definidos de usuários
- Ganhe confiança sobre os resultados com intervalos de confiança e avaliações em vários limites
- Avalie a distribuição dos conjuntos de dados
- Mergulhe profundamente em fatias individuais para explorar as causas-raiz e oportunidades de melhoria
Neste caderno, você vai usar Fairness Indicadores para corrigir problemas de equidade em um modelo de você treinar usando o Civil Comentários dataset . Assista a este vídeo para mais detalhes e contexto no cenário do mundo real isso é baseado em que é também uma das principais motivações para a criação de Equidade indicadores.
Conjunto de dados
Neste caderno, você vai trabalhar com o Civil Comentários conjunto de dados , aproximadamente 2 milhões de comentários públicos tornado público pela Civil Comentários plataforma em 2017 para investigação em curso. Este esforço foi patrocinado por Jigsaw , que já sediaram competições em Kaggle para ajudar a classificar comentários tóxicos, bem como minimizar o viés modelo não intencional.
Cada comentário de texto individual no conjunto de dados tem um rótulo de toxicidade, com o rótulo sendo 1 se o comentário for tóxico e 0 se o comentário não for tóxico. Dentro dos dados, um subconjunto de comentários é rotulado com uma variedade de atributos de identidade, incluindo categorias de gênero, orientação sexual, religião e raça ou etnia.
Configurar
Instale fairness-indicators e witwidget .
pip install -q -U pip==20.2pip install -q fairness-indicatorspip install -q witwidget
Você deve reiniciar o tempo de execução do Colab após a instalação. Select Runtime> Restart tempo de execução a partir do menu Colab.

Baixe e analise os dados
Por padrão, este notebook baixa uma versão pré-processada desse conjunto de dados, mas você pode usar o conjunto de dados original e executar novamente as etapas de processamento, se desejar. No conjunto de dados original, cada comentário é rotulado com a porcentagem de avaliadores que acreditam que um comentário corresponde a uma identidade específica. Por exemplo, um comentário pode ser rotulado com o seguinte: { masculino: 0,3, feminino: 1,0, transgênero: 0,0, heterossexual: 0,8, homossexual_gay_or_lésbica: 1,0 } A etapa de processamento agrupa a identidade por categoria (gênero, orientação_sexual etc.) e remove identidades com pontuação inferior a 0,5. Assim, o exemplo acima seria convertido para o seguinte: de avaliadores que acreditam que um comentário corresponde a uma determinada identidade. Por exemplo, o comentário seria marcado com o seguinte: { gênero: [feminino], orientação_sexual: [heterossexual, homossexual_gay_or_lésbica] }

Use o TFDV para analisar os dados e encontrar possíveis problemas neles, como valores ausentes e desequilíbrios de dados, que podem levar a disparidades de justiça.

O TFDV mostra que existem alguns desequilíbrios significativos nos dados que podem levar a resultados tendenciosos do modelo.
O rótulo de toxicidade (o valor previsto pelo modelo) está desbalanceado. Apenas 8% dos exemplos no conjunto de treinamento são tóxicos, o que significa que um classificador pode obter 92% de precisão ao prever que todos os comentários não são tóxicos.
Nos domínios relativos aos termos identitários, apenas 6,6 mil dos 1,08 milhões (0,61%) exemplos de formação tratam da homossexualidade, sendo ainda mais raros os relacionados com a bissexualidade. Isso indica que o desempenho nessas fatias pode sofrer devido à falta de dados de treinamento.
Preparar os dados
Defina um mapa de recursos para analisar os dados. Cada exemplo terá um rótulo, comentário de texto, e identidade apresenta sexual orientation , gender , religion , race e disability que estão associados com o texto.
BASE_DIR = tempfile.gettempdir()
TEXT_FEATURE = 'comment_text'
LABEL = 'toxicity'
FEATURE_MAP = {
# Label:
LABEL: tf.io.FixedLenFeature([], tf.float32),
# Text:
TEXT_FEATURE: tf.io.FixedLenFeature([], tf.string),
# Identities:
'sexual_orientation':tf.io.VarLenFeature(tf.string),
'gender':tf.io.VarLenFeature(tf.string),
'religion':tf.io.VarLenFeature(tf.string),
'race':tf.io.VarLenFeature(tf.string),
'disability':tf.io.VarLenFeature(tf.string),
}
Em seguida, configure uma função de entrada para alimentar dados no modelo. Adicione uma coluna de peso a cada exemplo e aumente os exemplos tóxicos para explicar o desequilíbrio de classe identificado pelo TFDV. Use apenas recursos de identidade durante a fase de avaliação, pois apenas os comentários são inseridos no modelo durante o treinamento.

Visualize dados usando a ferramenta What-if
Nesta seção, você usará a interface visual interativa da ferramenta What-If para explorar e manipular dados em um nível micro.
Cada ponto no gráfico de dispersão no painel direito representa um dos exemplos no subconjunto carregado na ferramenta. Clique em um dos pontos para ver detalhes sobre este exemplo específico no painel esquerdo. O texto do comentário, a toxicidade da verdade do terreno e as identidades aplicáveis são mostrados. Na parte inferior deste painel esquerdo, você vê os resultados de inferência do modelo que acabou de treinar.
Modificar o texto do exemplo e, em seguida, clique no botão Executar inferência vista como as alterações causou a previsão de toxicidade percebida à mudança.
DEFAULT_MAX_EXAMPLES = 1000
# Load 100000 examples in memory. When first rendered,
# What-If Tool should only display 1000 of these due to browser constraints.
def wit_dataset(file, num_examples=100000):

Indicadores de equidade de renderização
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 os limites exibidos, usando os menus suspensos na parte superior da visualização.
O widget Indicador de imparcialidade é integrado à ferramenta What-If renderizada acima. Se você selecionar uma fatia dos dados no gráfico de barras, a ferramenta What-If será atualizada para mostrar exemplos da fatia selecionada. Quando recarrega dados na ferramenta What-If acima, tente modificar a cores pela toxicidade. Isso pode fornecer uma compreensão visual do equilíbrio de toxicidade dos exemplos por fatia.

Com esse conjunto de dados e tarefa específicos, taxas sistematicamente mais altas de falsos positivos e falsos negativos para certas identidades podem levar a consequências negativas. Por exemplo, em um sistema de moderação de conteúdo, uma taxa de falsos positivos acima do geral para um determinado grupo pode fazer com que essas vozes sejam silenciadas. Portanto, é importante avaliar regularmente esses tipos de critérios à medida que você desenvolve e aprimora modelos e utiliza ferramentas como indicadores de justiça, TFDV e WIT para ajudar a esclarecer possíveis problemas. Depois de identificar os problemas de imparcialidade, você pode experimentar novas fontes de dados, balanceamento de dados ou outras técnicas para melhorar o desempenho em grupos com baixo desempenho.
Veja aqui para mais informações e orientações sobre como usar Fairness indicadores.
Use os resultados da avaliação de imparcialidade
O eval_result objeto, prestados acima em render_fairness_indicator() , tem a sua própria API que você pode aproveitar para ler os resultados TFMA em seus programas.
Obtenha fatias e métricas avaliadas
Use get_slice_names() e get_metric_names() para obter as fatias avaliadas e métricas, respectivamente.
