Feeding data into a Siamese Network
For my project I have decided to use a CNN with triplet loss for feature embedding. I have preprocessed my data to create 72xframes windows, I have defined functions that get me batches thereof with an anchor, positive and negative image and I am…

How to change the default batch size of Keras layers when compiling a model?
I have a simple model in Keras 2.8.0 that takes a batch of images and outputs the pairwise distance of their embeddings:
inp = layers.Input((28, 28, 1))
x = layers.Conv2D(64, (3, 3), padding='same')(inp)
x = layers.MaxPooling2D()(x)
x =…

How can I iterate (loop) over i, j values in order?
I have this code to find Pythagorean triplets:
for i in range(1,31):
for j in range(1,31):
for k in range(1,31):
if((i**2 + j**2)==(k**2)):
print(i,",",j,",",k)
I get this result:
3 , 4 , 5
4 , 3 , 5
5 , 12 ,…

Problem with tensor shape when implementing a custom loss function for my model in Tensorflow
I picked up the idea of triplet loss and global orthogonal regularization from this paper http://cs230.stanford.edu/projects_fall_2019/reports/26251543.pdf. However, I keep getting caught up in an tensor shape error.
After I define modelv1 as the…

Triplet Loss model not getting any result Siamese Model
I have been trying to build a Siamese model using the Triplet Loss addon by Tensorflow (this tries to, working in a batch of anchor, positive(same person) and negative(other person), minimize the distance between faces of identical identity and…

Store a list of triplet with constant look up
I would like to store a list of triplets of Enums- say List<> where I should be able to look up by any of the fields. What I mean is, say I store something like,
List<> list;
list[0] = [ObjectOfEnum1,…

Random triplet number generator
I would like to create code for a random number generator for predetermined sets of triplets (200 sets in total to randomize). I would like the sets of triplets to form a set of six numbers and the set of triplets to remain unique.

Three numbers in an array that sum up to a target sum in O(n)
Recently hashedin asked the triplet sum problem where three numbers are supposed to add up to a target sum. They said to do it in O(n).
I have tried doing it in O(n^2). First, i sorted the array and then for searching the combination i had to apply…

Correctly submitting 3 inputs to a Keras model based on Triplet Loss
I'm working on a model consisting in 2 parts, as i discussed in this question: the first should take the elements of a triplet (consisting in an anchor, a positive example and a negative example, same principle adopted in FaceNet) and turn them into…

Triplet loss on text embeddings with keras
I'd start saying i'm quite new to Keras and machine learning in general. I'm trying to build an "experimental" model consisting of two parts:
An "encoder" which takes a string (containing a long series of attributes, i'm using the DBLP-ACM…
