Its not a perfect process, but it works well most of the time.
In the realm of artificial intelligence, this is called the one-shot learning challenge.

In recent years, one-shot learning AI has found successful applications including facial recognition and passport checks.
One of the interesting features of convnets is their ability to extract visual features from images at different levels.
Most moderncomputer vision applicationsuse convolutional neural networks.
Imagine what this would mean for a facial recognition system used at an international airport.
This is where one-shot learning comes into play.
Instead of treating the task as a classification problem, one-shot learning turns it into a difference-evaluation problem.
In essence, the Siamese neural online grid is not much different from other convolutional neural nets.
It takes images as input and encodes their features into a set of numbers.
The difference comes in the output processing.
Triplet loss
To achieve this goal, we use a function called triplet loss.
Training the Siamese web link still requires a fairly large set of APN trios.
But creating the training data is much easier than the classic datasets that need each image to be labeled.
you’ve got the option to generate 1,800 APN trios from this dataset.
Ideally, your dataset should have a diversity of face images to better generalize across different features.
Another good idea is to use a previously trained convolutional neural data pipe and finetune it for one-shot learning.
The limits of one-shot learning
Although very attractive, one-shot learning does have some limitations.
Each Siamese neural data pipe is just useful for the one task it has been trained on.
The neural networks are also sensitive to other variations.
One-shot learning is an exciting and active area of research.
There are other variations of the method, including zero-shot and few-shot learning.
