Exercício - Melhorar a qualidade da conclusão

Concluído

Agora temos uma compreensão dos componentes de um prompt e como usar os componentes para construir um prompt para gerar conclusões de alta qualidade.

Vamos atualizar o aplicativo de recomendação de caminhada que iniciamos no exercício anterior para incorporar algumas dessas técnicas.

Atualizar o prompt do sistema

Ao classificar uma avaliação de produto, queremos apenas que o modelo nos diga se a avaliação é positiva, neutra ou negativa. Vamos atualizar o prompt que o modelo recebe para que ele tenha a melhor chance de fornecer uma resposta de alta qualidade.

O prompt do sistema atual é OK, mas podemos obter o modelo para recomendar caminhadas mais apropriadas e emocionantes, seguindo as melhores práticas na construção rápida. Vamos deixar um pouco mais claras as instruções sobre como o modelo deve agir

Adicionar instruções

  1. Abra o projeto HikingConversationsAI que você criou anteriormente.

  2. No arquivo Program.cs, localize a systemPrompt variável que é usada para dizer ao modelo seus traços de personalidade e quaisquer regras que ele precisa seguir.

  3. Remova todo o texto existente da variável e adicione o seguinte que descreve como o modelo deve agir e as regras que deve seguir:

    var systemPrompt = 
    """
    You are a hiking enthusiast who helps people discover fun hikes in their area. You are upbeat and friendly. You introduce yourself when first saying hello. When helping people out, you always ask them for this information to inform the hiking recommendation you provide:
    
    1. Where they are located
    2. What hiking intensity they are looking for
    """;
    

Adicionar conteúdo principal

O conteúdo primário refere-se ao texto que está sendo transformado pelo modelo e o que fazer com ele. Neste caso, as próprias recomendações de caminhadas.

  1. Atualize a systemPrompt variável para instruir o modelo sobre o que fazer com o conteúdo.

    var systemPrompt = 
    """
    You are a hiking enthusiast who helps people discover fun hikes in their area. You are upbeat and friendly. You introduce yourself when first saying hello. When helping people out, you always ask them for this information to inform the hiking recommendation you provide:
    
    1. Where they are located
    2. What hiking intensity they are looking for
    
    You will then provide three suggestions for nearby hikes that vary in length after you get that information. You will also share an interesting fact about the local nature on the hikes when making a recommendation.
    """;
    

Melhorar os pedidos de recomendação de caminhadas

Agora que o modelo tem melhores informações sobre como deve agir e as regras que deve seguir, vamos fazer as solicitações que recebe melhor para que as caminhadas que recomenda possam ser mais adequadas.

Seja específico

O pedido anterior apenas disse que a caminhada deve ser extenuante com uma excelente vista. Vamos dizer ao modelo exatamente o que estamos procurando.

  1. Encontre a hikeRequest variável e atualize-a para ter as seguintes informações de solicitação específicas.

    var hikeRequest = 
    """
    I live near Seattle and would like a strenuous hike around the I-90 corridor that ends with
    a view that is amazing. I don't mind driving for a long time, even if it's over the pass.
    I've heard the Enchantments are nice.
    I don't want the hike to be over 10 miles round trip. I'd consider a point-to-point hike.
    I want the hike to be as seculuded as possible. I don't want to see many people.
    I would like it to be as bug free as possible. I would also like to avoid any Forest Service roads.
    """;
    
  2. Execute o aplicativo com dotnet run e veja o que ele recomenda agora. Aqui está um exemplo que recebemos de uma corrida:

    Great! Based on your preferences, I'd recommend the following strenuous hikes with amazing views near the I-90 corridor:
    
    1. Mt. Defiance - This hike is a challenging out-and-back trail that is about 10 miles long round trip and boasts stunning views of the Cascade Range from the summit. This trail is relatively secluded and is not located near any Forest Service roads. An interesting fact about this hike is that it passes through an old-growth forest with several old cedar trees.
    
    2. Mailbox Peak - This is another challenging out-and-back trail that is roughly 9.4 miles long round trip. At the summit, hikers will be rewarded with breathtaking views of the surrounding mountains and valleys. Although this hike can be popular, starting early in the morning may help you avoid larger crowds. Additionally, this hike is known to be one of the steepest and most difficult hikes in the area.
    
    3. Talapus and Ollalie Lakes - This hike is less strenuous than the first two and is a point-to-point hike that is about 8 miles long round trip. Despite being less challenging, this hike still offers stunning views of two beautiful alpine lakes and has a relatively low amount of traffic. Interesting fact, this trail is within the Alpine Lakes Wilderness and hikers should keep an eye out for wildlife, including black bears, during their visit.
    
    Hope this helps and happy hiking!
    

Isto é muito melhor! A resposta é seguir as regras do prompt do sistema e fornecer informações detalhadas da descrição da caminhada solicitada.

Se você olhar de perto, a recomendação de caminhada número 3 diz que é tanto um ponto a ponto quanto uma caminhada de ida e volta. Vamos alterar o prompt de solicitação de recomendação para ver se podemos evitar essa desinformação.

Cadeia de pensamento

Pedir ao modelo que forneça uma contabilidade passo a passo de seu processo de pensamento deve ajudá-lo a recomendar recomendações ainda mais precisas.

  1. Atualize a hikeRequest variável para ser a seguinte:

    var hikeRequest = 
    """
    I live near Seattle and would like a strenous hike around the I-90 corridor that ends with
    a view that is amazing. I don't mind driving for a long time, even if it's over the pass.
    I've heard the Enchantments are nice.
    I don't want the hike to be over 10 miles round trip. I'd consider a point-to-point hike.
    I want the hike to be as seculuded as possible. I don't want to see many people.
    I would like it to be as bug free as possible. I would also like to avoid any Forest Service roads.
    
    In the response for each hike, provide a step-by-step accounting of why you picked the hike that you did based
    off of the attributes I provided above.
    """;
    
  2. Execute o aplicativo com dotnet run e veja o que ele recomenda agora. Aqui está um exemplo que recebemos de uma corrida:

    Great, based on your preferences, I have three hiking recommendations for you near the I-90 corridor.
    
    1. Mount Si - Distance: 8 miles round-trip, Elevation gain: 3,150 ft
    Located near North Bend, Mount Si is a strenuous hike that ends with beautiful views of the Cascade Mountains and the Snoqualmie Valley. Although it's a popular hike, you can still find secluded areas if you hike a bit further from the trailhead. This trail offers a challenging uphill climb through forests and rocky terrain before reaching the summit. The bugs can be present in the summer, so be sure to bring some repellent. The trailhead is easy to find, and there is no need to take any forest service roads.
    
    2. Snow Lake - Distance: 7.2 miles round-trip, Elevation gain: 1,800 ft
    Located off of the Snoqualmie Pass, Snow Lake is a moderately challenging hike that offers great views of alpine scenery and serene mountain lake. The trail is a bit rocky but is well-maintained. Although it's a popular hike, you can still find some secluded spots around the lake. The hike starts off on the Alpental Ski Area, with no need to take any forest service roads. There is some bug activity on this trail in the summer months.
    
    3. Granite Mountain - Distance: 8.6 miles round-trip, Elevation gain: 3,800 ft
    Located off of the I-90 corridor near exit 47, Granite Mountain is a strenuous hike that offers sweeping views of the mountains and valleys of the Alpine Lakes Wilderness. The trail is challenging, but well worth it. The trailhead is easy to find, and there is no need to take any forest service roads. There may be some bug activity on this trail, so it's best to bring some repellent.
    
    I hope you find these recommendations helpful!
