Data collection – fetching the textbook data

For this study, we’re analyzing a textbook about insects. Let’s fetch and process this data:

text = urlopen(‘https://www.gutenberg.org/cache/epub/10834/pg10834.txt’).read().decode()
documents = list(filter(lambda x: len(x) > 100, text.split(‘\r\n\r\n’)))
print(f’There are {len(documents)} documents/paragraphs’)

Here, we’re downloading the text from its source, splitting it into paragraphs, and ensuring we only keep the more content-rich ones (those longer than 100 characters). We end up with 79 paragraphs in this example.

Converting text to embeddings

The core of our analysis lies in converting text data to embeddings. Let’s achieve this:

question_embedding = np.array(get_embedding(QUESTION))
embeddings=[get_embedding(document) for document in documents]
embeddings = np.array(embeddings)

We loop through each document, convert it into an embedding using our specified engine, and store the embeddings in a numpy array for efficient operations.

Querying – searching for relevant information

With our data transformed, let’s pose a natural language query and find the most relevant document using our vector embedding. We are using a kind of nearest-neighbor algorithm, as we have seen:

QUESTION = ‘How many horns does a flea have?’
question_embedding = np.array(get_embedding(QUESTION, engine=ENGINE))
hits = util.semantic_search(question_embedding, embeddings, top_k=1)[0]
print(f’Question: {QUESTION}\n’)
for i, hit in enumerate(hits):
    print(f’Document {i + 1} Cos_Sim {hit[“score”]:.3f}:\n\n{documents[hit[“corpus_id”]]}’)
    print(‘\n’)

We encode our question into an embedding, and then use semantic search to find the closest matching document from our dataset. The result provides us with insights into our query. With this structure, we’ve transformed our code into a more instructive, step-by-step guide that should be more accessible and understandable.

Concluding thoughts – the power of modern pre-trained models

In the rapidly evolving world of ML and AI, what we’ve witnessed in this case study is just a small taste of the vast potential of modern pre-trained models. Here’s a brief contemplation on their profound impact:

• Unprecedented efficiency: Gone are the days when we had to train models from scratch for every new task. Pre-trained models, fine-tuned for specific tasks, have removed significant barriers in terms of time, computation, and resources. With a few lines of code, we were able to access and harness the power of models that have trained on vast amounts of data, a task that would’ve been monumental just a decade ago.
• Broadened accessibility: Not only do pre-trained models save time, but they also democratize access to cutting-edge AI technology. Developers, researchers, and hobbyists without extensive ML backgrounds or access to massive compute resources can now embark on AI projects with ease.
• Rapid prototyping: The ability to quickly spin up models and test ideas allows for a more iterative and innovative approach to problem-solving. This rapid prototyping is especially important in industries that require quick turnarounds or where the first-mover advantage is crucial.
• Versatility and scalability: The models we use today, such as OpenAI’s embedding engines, are versatile. Whether you’re building a semantic search engine, a recommendation system, or any other application that requires understanding context, these models can be your cornerstone. As your project grows, these models can scale with you, ensuring consistent performance.

In conclusion, the landscape of AI has been revolutionized by the advent of pre-trained models. Their power and efficiency underscore a new era where building advanced AI prototypes and projects is no longer a distant dream but an easily attainable reality. As technology continues to advance, it’s exciting to ponder what further innovations lie on the horizon and how they will shape our interconnected world.
