Siamese Network in Keras

I‘m looking for a minimal applied example for the implementation of a (one shot) Siamese Network, preferably in Keras. I‘m well aware of the various data science online pages and the respective examples and exercises that can be found there.…

Why does Siamese neural networks use tied weights and how do they work?

Reading this paper on one-shot learning "Siamese Neural Networks for One-shot Image Recognition" I was introduced to the idea of Siamese Neural Networks. What I did not fully grasp was what they meant by this line: This objective is combined with…

What is zero-shot vs one-short vs few-shot learning?

Are there any papers/research work that deals with generalizing the matrix of how the *-shot(s) learning are defined? There's a wide variety of papers that titled themselves as *-shot(s) learning, with some variants of how *-shots are defined,…

Few shot learning and object detector

I have a dataset with a lot of classes (~10000+) but few examples by classes (~15-). I want to classify these classes, but there are some specificities. My examples provide from a video stream. Currently, I use a detector (like YOLO) to do object…

what does one Shot learning mean? do they only need one image to train for some new class detection?

Being new to deep learning I am somewhat struggling to grasp the idea of one shot learning. Let us say I have a class to detect which didn't exist in training dataset such as COCO or Image NET. Can I train model for that class using only image or…

Source to learn/understand one-shot learning

I'm currently looking into one-shot learning and I wonder if there are any good sources/tutorials out there, which demonstrate one-shot learning in a (more or less) "hands-on" way? Also some hints to indroductory literature to one-shot learning…

How do I test one-shot model preformance against flawed categories?

I'm in the process of reworking the ASAM database. Excerpted, it looks like this: 4155 PIRATES BULK CARRIER GULF OF ADEN: Bulk carrier fired upon 3 Aug 09 at 1500 UTC while underway in position 13-46.5N 050-42.3E. Ten heavily armed pirates…

Should number of classes be the same in few shot learning train and test?

I used to believe in k-way-n-shot few-shot learning, k and n (number of classes and samples from each class respectively) must be the same in train and test phases. But now I come across a git repository for few-shot learning that uses different…

Siamese Network for face comparison wont learn, accuracy stuck on 0.5, and loss stuck too

I'm trying to train a siamese network which contains a CNN and an embedding layer at the end to yield 2 similar (close) vectors for 2 images of the same person. I'm using the LFW_Cropped dataset, and some custom made generators. The generators are…

Should I normalise image pixel wise for pretrained VGG16 model

My goal is to use pre-trained VGG16 to compute the feature vectors excluding the top layer. I want to compute embedding(no training involved) per image one by one rather than feeding batches to the network as this network is just to compute…

Binary Classification - One Hot Encoding preventing me using Test Set

I have a preprocessing pipeline that includes replacing missing values and onehotencoding for the categorical variables. When I try to use my model on the test set, it explains that the number of columns it expects differs. This is due to one hot…

Difference between Siamese Network and Prototypical Networks for One Shot Learning

I am having a bit of trouble understanding how the architecture of prototypical networks in a one shot learning use case differs from Siamese networks. If I’m understanding correctly, Siamese networks maps pairwise examples using same weights and…
