Questions tagged [neural-architecture-search]

For questions related to the concept of neural (network) architecture search (NAS), which is a way of automating the design (that is, the hyper-parameters) of a neural network. NAS is related to neuroevolution, given that neuroevolution can be used to perform NAS, but neuroevolution is not the only way of performing NAS. For example, reinforcement learning can also be used to perform NAS.

Should I consider this a normal phenomenon, or should I consider it an anomaly?

I am doing a network architecture search (NAS). I have two directories, train_data_npy and valid_data_npy where there are 3013 ...

Why are the non-linear activations in deep nets not learned?

Why can we not parametrize and learn the non-linear activations? For example, if we look at leaky ReLu which equals to $f(y)=y$ for $y>0$ and $f(y)=\alpha y$ for $y<0$, it seems that we can ...

Are there metrics for image complexity for informing neural network design?

BACKGROUND: I am trying to think of rational approaches to designing deep learning models for image classification. One thought is to quantify the complexity of image datasets and use that to inform ...

Is it possible to learn the number of layers?

Is it possible, in a transformer or other deep architecture, to include the number of layers as a parameter of the model so it could be learned? In fact, I have a keras layer that I use to change the ...

A neural network to learn the connection between two totally different type of images

I have a dataset of two different type of images. Say, I have images of a person and his all 10 fingerprints. I want to create a relation between them to predict one from another. How I can do that ...

How can an "architectural motif" be extracted from a trained MLP?

I am trying to reproduce the paper Synthetic Petri Dish: A novel surrogate model for Rapid Architecture Search. In the paper, the authors try to reduce the architecture of an MLP model trained on ...

Is it possible to train a neural network with 3 inputs and 12 outputs?

The selection of experimental data includes a set of vectors of different dimensions. The input is a 3-dimensional vector, and the output is a 12-dimensional vector. The sample size is 120 pairs of ...

When using Neural Architecture Search, how are the hyper-parameters chosen?

I have read a lot about NAS, but I still do not understand one concept: When setting up a neural network, hyperparameters (such as the learning rate, dropout rate, batch size, filter size, etc.) need ...

How is neural architecture search performed?

I have come across something that IBM offers called neural architecture search. You feed it a data set and it outputs an initial neural architecture that you can train. How is neural architecture ...
