Now, if you don’t know what any of those words mean, don’t worry, because neither do most people in the tech industry. But let me break it down for ya:
Embedding models are basically a way to represent text as numbers so that computers can understand them better. They work by taking all the words in a sentence and turning them into vectors (which is just fancy math speak for “lists of numbers”). These vectors can then be used to find similarities between different sentences or documents, which is super helpful when it comes to information retrieval.
Finetuning, on the other hand, is the process of taking an existing model and tweaking it to better fit your specific needs. In this case, we’re finetuning open-source embedding models for information retrieval by training them on a dataset that’s relevant to our particular use case (in this case, finding articles about AI).
Now, you might be wondering why anyone would bother with all of this when there are already plenty of pretrained embedding models available. Well, the answer is simple: because those pretrained models aren’t always perfect for every situation. Sometimes they need a little extra tweaking to really shine. And that’s where finetuning comes in!
So how do we go about finetuning an open-source embedding model? First, we download the dataset we want to use (in this case, a collection of articles from various tech publications). Then we preprocess the data by cleaning it up and removing any stop words or punctuation. Next, we split the data into training and testing sets so that we can evaluate our performance on both.
Once we have our dataset ready to go, we load in our chosen embedding model (in this case, GloVe) and initialize a new neural network with it. We then train the model using backpropagation and stochastic gradient descent for several epochs until we reach convergence. Finally, we evaluate the performance of our finetuned model on both the training and testing sets to see how well it’s doing.
And that’s it! Finetuning an open-source embedding model for information retrieval is really not as complicated as it might seem at first glance. With a little bit of data preprocessing, some basic neural network architecture, and a few lines of code, you can have your very own customized embedding model up and running in no time!
So if you’re tired of relying on those ***** pretrained models for all your information retrieval needs, why not give finetuning a try? Who knows it might just be the key to unlocking all sorts of new insights and discoveries in the world of AI.
