Fixing Hallucination with Data Bases
Large Language Models (LLMs) have an information freshness downside. Even a number of the strongest fashions, like GPT-4, have no thought about latest occasions.
The world, in line with LLMs, is frozen in time. They solely know the world because it appeared by their coaching information.
That creates issues for any use case that depends on up-to-date data or a selected dataset. For instance, you’ll have inside firm paperwork you’d wish to work together with by way of an LLM.
The primary problem is including these paperwork to the LLM, we might attempt coaching the LLM on these paperwork, however that is time-consuming and costly. And what occurs when a brand new doc is added? Coaching for each new doc added is past inefficient — it’s merely inconceivable.
So, how will we deal with this downside? We are able to use retrieval augmentation. This method permits us to retrieve related data from an exterior data base and provides that data to our LLM.
The exterior data base is our “window” into the world past the LLM’s coaching information. On this chapter, we are going to be taught all about implementing retrieval augmentation for LLMs utilizing LangChain.
Creating the Data Base
Now we have two major forms of data for LLMs. The parametric data refers to every part the LLM realized throughout coaching and acts as a frozen snapshot of the world for the LLM.
The second sort of data is supply data. This information covers any data fed into the LLM by way of the enter immediate. After we speak about retrieval augmentation, we’re speaking about giving the LLM worthwhile supply data.
(You possibly can comply with together with the next sections utilizing the Jupyter notebook here!)
Getting Information for our Data Base
To assist our LLM, we have to give it entry to related supply data. To try this, we have to create our data base.
We begin with a dataset. The dataset used naturally is dependent upon the use case. It may very well be code documentation for an LLM that should assist write code, firm paperwork for an inside chatbot, or anything.
In our instance, we are going to use a subset of Wikipedia. To get that information, we are going to use Hugging Face datasets like so:

Most datasets will comprise information that embody lots of textual content. Due to this, our first activity is often to construct a preprocessing pipeline that chunks these lengthy bits of textual content into extra concise chunks.
Creating Chunks
Splitting our textual content into smaller chunks is crucial for a number of causes. Primarily we wish to:
- Enhance “embedding accuracy” — it will enhance the relevance of outcomes later.
- Scale back the quantity of textual content fed into our LLM as supply data. Limiting enter improves the LLM’s capacity to comply with directions, reduces era prices, and helps us get sooner responses.
- Present customers with extra exact data sources as we are able to slim down the knowledge supply to a smaller chunk of textual content.
- Within the case of very lengthy chunks of textual content, we are going to exceed the utmost context window of our embedding or completion fashions. Splitting these chunks makes it attainable so as to add these longer paperwork to our data base.
To create these chunks, we first want a approach of measuring the size of our textual content. LLMs don’t measure textual content by phrase or character — they measure it by “tokens”.
A token is often the scale of a phrase or sub-word and varies by LLM. The tokens themselves are constructed utilizing a tokenizer. We will probably be utilizing gpt-3.5-turbo
as our completion mannequin, and we are able to initialize the tokenizer for this mannequin like so:
import tiktoken # !pip set up tiktoken
tokenizer = tiktoken.get_encoding('p50k_base')
Utilizing the tokenizer, we are able to create tokens from plain textual content and depend the variety of tokens. We are going to wrap this right into a operate referred to as tiktoken_len
:
In[28]:
# create the size operate
def tiktoken_len(textual content):
tokens = tokenizer.encode(
textual content,
disallowed_special=()
)
return len(tokens)
tiktoken_len("hiya I'm a piece of textual content and utilizing the tiktoken_len operate "
"we are able to discover the size of this chunk of textual content in tokens")
With our token counting operate prepared, we are able to initialize a LangChain RecursiveCharacterTextSplitter
object. This object will enable us to separate our textual content into chunks not than what we specify by way of the chunk_size
parameter.
from langchain.text_splitter import RecursiveCharacterTextSplitter
text_splitter = RecursiveCharacterTextSplitter(
chunk_size=400,
chunk_overlap=20,
length_function=tiktoken_len,
separators=["nn", "n", " ", ""]
)
Now we break up the textual content like so:

chunks = text_splitter.split_text(information[6]['text'])[:3]

None of those chunks are bigger than the 400
chunk dimension restrict we set earlier:
In[7]:
tiktoken_len(chunks[0]), tiktoken_len(chunks[1]), tiktoken_len(chunks[2])
With the text_splitter
, we get nicely-sized chunks of textual content. We’ll use this performance through the indexing course of later. For now, let’s check out embeddings.
Creating Embeddings
The vector embeddings are very important to retrieving related context for our LLM. We take the chunks of textual content we’d wish to retailer in our data base and encode every chunk right into a vector embedding.
These embeddings can act as “numerical representations” of the which means of every chunk of textual content.
That is attainable as a result of we create the embeddings with one other AI language mannequin that has realized to translate human-readable textual content into AI-readable embeddings.
We then retailer these embeddings in our vector database (extra on this quickly) and may discover textual content chunks with comparable meanings by calculating the gap between embeddings in vector house.
The embedding mannequin we are going to use is one other OpenAI mannequin referred to as text-embedding-ada-002
. We are able to initialize it by way of LangChain like so:
from langchain.embeddings.openai import OpenAIEmbeddings
model_name = 'text-embedding-ada-002'
embed = OpenAIEmbeddings(
document_model_name=model_name,
query_model_name=model_name,
openai_api_key=OPENAI_API_KEY
)
Now we are able to embed our textual content:
In[10]:
texts = [
'this is the first chunk of text',
'then another second chunk of text is here'
]
res = embed.embed_documents(texts)
len(res), len(res[0])
From this, we get two embeddings as we handed in two chunks of textual content. Every embedding is a 1536-dimensional vector. This dimension is just the output dimensionality of text-embedding-ada-002
.
With that, we’ve got our dataset, textual content splitter, and embedding mannequin. Now we have every part wanted to start setting up our data base.
Vector Database
A vector database is a sort of data base that permits us to scale the search of comparable embeddings to billions of information, handle our data base by including, updating, or eradicating information, and even do issues like filtering.
We will probably be utilizing the Pinecone vector database. To make use of it, we want a free API key. Then we initialize our database index like so:
import pinecone
index_name = 'langchain-retrieval-augmentation'
pinecone.init(
api_key="YOUR_API_KEY", # discover api key in console at app.pinecone.io
atmosphere="YOUR_ENV" # discover subsequent to api key in console
)
# we create a brand new index
pinecone.create_index(
identify=index_name,
metric='dotproduct',
dimension=len(res[0]) # 1536 dim of text-embedding-ada-002
)
Then we connect with the brand new index:
In[12]:
index = pinecone.GRPCIndex(index_name)
index.describe_index_stats()
Out[12]:
{'dimension': 1536,
'index_fullness': 0.0,
'namespaces': {},
'total_vector_count': 0}
We are going to see that the brand new Pinecone index has a total_vector_count
of 0
as a result of we haven’t added any vectors but. Our subsequent activity is to do this.
The indexing course of consists of us iterating by the info we’d like so as to add to our data base, creating IDs, embeddings, and metadata — then including these to the index.
We are able to do that in batches to hurry up the method.
from tqdm.auto import tqdm
from uuid import uuid4
batch_limit = 100
texts = []
metadatas = []
for i, document in enumerate(tqdm(information)):
# first get metadata fields for this document
metadata = {
'wiki-id': str(document['id']),
'supply': document['url'],
'title': document['title']
}
# now we create chunks from the document textual content
record_texts = text_splitter.split_text(document['text'])
# create particular person metadata dicts for every chunk
record_metadatas = [{
"chunk": j, "text": text, **metadata
} for j, text in enumerate(record_texts)]
# append these to present batches
texts.lengthen(record_texts)
metadatas.lengthen(record_metadatas)
# if we've got reached the batch_limit we are able to add texts
if len(texts) >= batch_limit:
ids = [str(uuid4()) for _ in range(len(texts))]
embeds = embed.embed_documents(texts)
index.upsert(vectors=zip(ids, embeds, metadatas))
texts = []
metadatas = []
We’ve now listed every part. To verify the variety of information in our index, we name describe_index_stats
once more:
In[14]:
index.describe_index_stats()
Out[14]:
{'dimension': 1536,
'index_fullness': 0.1,
'namespaces': {'': {'vector_count': 27437}},
'total_vector_count': 27437}
Our index accommodates ~27K information. As talked about earlier, we are able to scale this as much as billions, however 27K is sufficient for our instance.
LangChain Vector Retailer and Querying
We assemble our index independently of LangChain. That’s as a result of it’s an easy course of, and it’s sooner to do that with the Pinecone consumer straight. Nevertheless, we’re about to leap again into LangChain, so we must always reconnect to our index by way of the LangChain library.
from langchain.vectorstores import Pinecone
text_field = "textual content"
# swap again to regular index for langchain
index = pinecone.Index(index_name)
vectorstore = Pinecone(
index, embed.embed_query, text_field
)
We are able to use the similarity search
methodology to make a question straight and return the chunks of textual content with none LLM producing the response.
In[16]:
question = "who was Benito Mussolini?"
vectorstore.similarity_search(
question, # our search question
okay=3 # return 3 most related docs
