Como usar GPT-3, GPT-J e GPT-Neo, com pouca aprendizagem de disparos

GPT-3, GPT-J e GPT-Neo são modelos de IA muito poderosos. Estamos aqui a mostrar-lhe como utilizar eficazmente estes modelos, graças à aprendizagem de poucos tiros. Poucas aprendizagens são como treinar/ajustar um modelo de IA, dando simplesmente alguns exemplos no seu prompt.

GPT-3

GPT-3, lançado pela OpenAI, é o modelo de IA mais poderoso alguma vez lançado para a compreensão e geração de texto.

Foi treinado em 175 mil milhões de parâmetros, o que o torna extremamente versátil e capaz de compreender praticamente tudo!

Pode fazer todo o tipo de coisas com o GPT-3 como chatbots, criação de conteúdos, extracção de entidades, classificação, sumarização, e muito mais. Mas é preciso alguma prática e utilizar correctamente este modelo não é fácil.

GPT-J e GPT-Neo

GPT-Neo e GPT-J são ambos modelos de processamento de linguagem natural de código aberto, criados por, um colectivo de investigadores que trabalham para a IA de fonte aberta (ver o website da EleutherAI).

O GPT-J tem 6 mil milhões de parâmetros, o que o torna o mais avançado processamento de linguagem natural de código aberto modelo a partir desta escrita. Esta é uma alternativa directa ao Curie GPT-3 propriedade da OpenAI.

Estes modelos são muito versáteis. Podem ser utilizados para quase todos os casos de utilização de Processamento de Linguagem Natural: geração de texto, sentimento análise, classificação, tradução automática,... e muito mais (ver abaixo). No entanto, a sua utilização eficaz por vezes é preciso praticar. O seu tempo de resposta (latência) também pode ser mais longo do que o processamento de linguagem natural padrão. modelos.

O GPT-J e o GPT-Neo estão ambos disponíveis na NLP Cloud API. Abaixo, mostramos-lhe exemplos obtidos utilizando o GPT-J endpoint da NLP Cloud na GPU, com o cliente Python. Se quiser copiar os exemplos, cole, por favor não se esqueça de adicionar a sua própria ficha API. A fim de instalar o cliente Python, execute primeiro o seguinte: pip install nlpcloud.

Aprendizagem com Poucas Coisas

A aprendizagem de poucos tiros consiste em ajudar um modelo de aprendizagem de máquinas a fazer previsões graças a apenas um par de exemplos. Não há necessidade de treinar um novo modelo aqui: modelos como GPT-3, GPT-J e GPT-Neo são tão grandes que podem adaptar-se facilmente a muitos contextos sem ser reeducado.

Dar apenas alguns exemplos ao modelo ajuda-o a aumentar drasticamente a sua precisão.

Em Processamento de Linguagem Natural, a ideia é passar estes exemplos juntamente com a sua entrada de texto. Veja os exemplos abaixo!

Note também que, se a aprendizagem de poucos tiros não for suficiente, pode também afinar o GPT-3 no website do OpenAI e o GPT-J na Nuvem NLP, de modo que o modelo é perfeitamente adaptado ao seu caso de utilização.

Pode testar facilmente a aprendizagem de poucos tiros no campo de jogos da NLP Cloud (experimente-o aqui).

Análise de Sentimento com GPT-J

    end_sequence="###",
    remove_end_sequence=True,
    remove_input=True)
print(generation["generated_text"])

Saída:

Positive

Como pode ver, o facto de primeiro darmos 3 exemplos com um formato adequado, leva o GPT-J a compreender que queremos realizar uma análise dos sentimentos. E o seu resultado é bom.

Pode ajudar o GPT-J a compreender os diferentes utilizando um delimitador personalizado como os seguintes: ###. Poderíamos usar perfeitamente algo mais como isto: ---. Ou simplesmente um novo linha. Depois definimos "end_sequence" que é um parâmetro NLP Cloud que diz ao GPT-J para parar de gerar conteúdo após uma nova linha + ###: end_sequence="###".

Geração de código HTML com GPT-J

import nlpcloud
client = nlpcloud.Client("gpt-j", "your_token", gpu=True)
generation = client.generation("""description: a red button that says stop
    code: <button style=color:white; background-color:red;>Stop</button>

    remove_end_sequence=True,
    remove_input=True)
print(generation["generated_text"])

Saída:

A geração de códigos com o GPT-J é realmente espantosa. Isto é em parte graças ao facto de que o GPT-J tem sido treinados em enormes bases de código.

generation = client.generation("""[Original]: America has changed dramatically during recent years. Not only has the number of graduates in traditional engineering disciplines such as mechanical, civil, electrical, chemical, and aeronautical engineering declined, but in most of the premier American universities engineering curricula now concentrate on and encourage largely the study of engineering science.  As a result, there are declining offerings in engineering subjects dealing with infrastructure, the environment, and related issues, and greater concentration on high technology subjects, largely supporting increasingly complex scientific developments. While the latter is important, it should not be at the expense of more traditional engineering.
        Rapidly developing economies such as China and India, as well as other industrial countries in Europe and Asia, continue to encourage and advance the teaching of engineering. Both China and India, respectively, graduate six and eight times as many traditional engineers as does the United States. Other industrial countries at minimum maintain their output, while America suffers an increasingly serious decline in the number of engineering graduates and a lack of well-educated engineers.

        [Original]: So how do you go about identifying your strengths and weaknesses, and analyzing the opportunities and threats that flow from them? SWOT Analysis is a useful technique that helps you to do this.
        What makes SWOT especially powerful is that, with a little thought, it can help you to uncover opportunities that you would not otherwise have spotted. And by understanding your weaknesses, you can manage and eliminate threats that might otherwise hurt your ability to move forward in your role.
        If you look at yourself using the SWOT framework, you can start to separate yourself from your peers, and further develop the specialized talents and abilities that you need in order to advance your career and to help you achieve your personal goals.

        [Original]: Jupiter is the fifth planet from the Sun and the largest in the Solar System. It is a gas giant with a mass one-thousandth that of the Sun, but two-and-a-half times that of all the other planets in the Solar System combined. Jupiter is one of the brightest objects visible to the naked eye in the night sky, and has been known to ancient civilizations since before recorded history. It is named after the Roman god Jupiter.[19] When viewed from Earth, Jupiter can be bright enough for its reflected light to cast visible shadows,[20] and is on average the third-brightest natural object in the night sky after the Moon and Venus.
        Jupiter is primarily composed of hydrogen with a quarter of its mass being helium, though helium comprises only about a tenth of the number of molecules. It may also have a rocky core of heavier elements,[21] but like the other giant planets, Jupiter lacks a well-defined solid surface. Because of its rapid rotation, the planet's shape is that of an oblate spheroid (it has a slight but noticeable bulge around the equator).

        [Original]: For all its whizz-bang caper-gone-wrong energy, and for all its subsequent emotional troughs, this week’s Succession finale might have been the most important in its entire run. Because, unless I am very much wrong, Succession – a show about people trying to forcefully mount a succession – just had its succession. And now everything has to change.
        The episode ended with Logan Roy defying his children by selling Waystar Royco to idiosyncratic Swedish tech bro Lukas Matsson. It’s an unexpected twist, like if King Lear contained a weird new beat where Lear hands the British crown to Jack Dorsey for a laugh, but it sets up a bold new future for the show. What will happen in season four? Here are some theories.
        Season three of Succession picked up seconds after season two ended. It was a smart move, showing the immediate swirl of confusion that followed Kendall Roy’s decision to undo his father, and something similar could happen here. This week’s episode ended with three of the Roy siblings heartbroken and angry at their father’s grand betrayal. Perhaps season four could pick up at that precise moment, and show their efforts to reorganise their rebellion against him. This is something that Succession undoubtedly does very well – for the most part, its greatest moments have been those heart-thumping scenes where Kendall scraps for support to unseat his dad – and Jesse Armstrong has more than enough dramatic clout to centre the entire season around the battle to stop the Matsson deal dead in its tracks.

O resumo do texto é uma tarefa complicada. O GPT-J é muito bom nisto, desde que se lhe dê o direito exemplos. O tamanho do resumo, e o tom do resumo, dependem muito dos exemplos que criado. Por exemplo, pode não criar o mesmo tipo de exemplos, quer esteja a tentar fazer um um resumo simples para crianças, ou um resumo médico avançado para médicos. Se o tamanho de entrada do GPT-J for demasiado pequeno para os seus exemplos de resumo, poderá querer afinar o GPT-J para a sua tarefa de sumarização.

[Blog article]: <h1>3 Tips to Increase the Effectiveness of Online Learning</h1>
<p>The hurdles associated with online learning correlate with the teacher’s inability to build a personal relationship with their students and to monitor their productivity during class.</p>
<h2>1. Creative and Effective Approach</h2>
<p>Each aspect of online teaching, from curriculum, theory, and practice, to administration and technology, should be formulated in a way that promotes productivity and the effectiveness of online learning.</p>
<h2>2. Utilize Multimedia Tools in Lectures</h2>
<p>In the 21st century, networking is crucial in every sphere of life. In most cases, a simple and functional interface is preferred for eLearning to create ease for the students as well as the teacher.</p>
<h2>3. Respond to Regular Feedback</h2>
<p>Collecting student feedback can help identify which methods increase the effectiveness of online learning, and which ones need improvement. An effective learning environment is a continuous work in progress.</p>

[Title]: 4 Tips for Teachers Shifting to Teaching Online 
[Blog article]: <h1>4 Tips for Teachers Shifting to Teaching Online </h1>
<p>An educator with experience in distance learning shares what he’s learned: Keep it simple, and build in as much contact as possible.</p>
<h2>1. Simplicity Is Key</h2>
<p>Every teacher knows what it’s like to explain new instructions to their students. It usually starts with a whole group walk-through, followed by an endless stream of questions from students to clarify next steps.</p>
<h2>2. Establish a Digital Home Base</h2>
<p>In the spirit of simplicity, it’s vital to have a digital home base for your students. This can be a district-provided learning management system like Canvas or Google Classrooms, or it can be a self-created class website. I recommend Google Sites as a simple, easy-to-set-up platform.</p>
<h2>3. Prioritize Longer, Student-Driven Assignments</h2>
<p>Efficiency is key when designing distance learning experiences. Planning is going to take more time and require a high level of attention to detail. You will not be able to correct mistakes on the fly or suddenly pivot when kids are disengaged.</p>
<h2>4. Individual Touchpoints Are Game-Changers</h2>
<p>You can create these touchpoints through any medium you like: emails, video messages, phone calls, messages through your learning management system, comments on shared documents, etc.</p>

<h1>Text Generation API</h1>
<h2>What is Text Generation?</h2>
<p>Text generation is the process of generating text from a block of text. It is not simply the inverse of summarization: a text generator will take a short piece of text as an input and generate a longer one.</p>
<p>For example you have the following text:</p>
Ahead of the opening of the meeting,
<p>In this case the goal of the API is to automatically generate the following:</p>
Ahead of the opening of the meeting, Prime Minister Justin Trudeau spoke to reporters at the Montreal airport where he was travelling to speak at the conference.
<p>So basically we want to leverage the output of the API as the input for the text generator, and we will then be able to generate some sentences based on the input we already have.</p>
<h2>Text generation with GPT-2</h2>
<p>We will leverage GPT-2 in order to have a starting point for the text generator. In this case, we will use the API as the input for the text generator, and we will use the output of the API as the input for GPT-2.
However, we want to fine-tune GPT-2 to generate more complex sentences and to have better results.</p>

Não é impressionante? Este artigo de blogue gerado é pequeno mas pode gerar artigos muito mais longos. O A estrutura do post gerado no blogue depende realmente da estrutura que utilizou nos seus poucos exemplos de fotos. A fim de obter estruturas mais complexas e conteúdos mais relevantes, o ajuste fino do GPT-J é a chave.

Conclusão

Como pode ver, a aprendizagem de poucos tiros é uma grande técnica que ajuda o GPT-3, GPT-J e GPT-Neo a alcançar coisas! A chave aqui é passar um contexto correcto antes de fazer o seu pedido.

Mesmo para a simples geração de texto, é recomendado passar o máximo de contexto possível, a fim de ajudar o modelo.

Espero que o tenha achado útil! Se tiver algumas perguntas sobre como tirar o máximo partido destes modelos, por favor não hesite em perguntar-nos.
