Those who are looking for an answer to the question «Why neural networks should not work?» often ask the following questions:

💻 How neural networks work?

A neural network is trained by adjusting neuron input weights based on the network's performance on example inputs. If the network classifies an image correctly, weights contributing to the correct answer are increased, while other weights are decreased.

💻 What neural networks work?

A neural network (also called an artificial neural network) is an adaptive system that learns by using interconnected nodes or neurons in a layered structure that resembles a human brain. A neural network can learn from data—so it can be trained to recognize patterns, classify data, and forecast future events.

💻 Why neural networks work?

Neural Networks can have a large number of free parameters (the weights and biases between interconnected units) and this gives them the flexibility to fit highly complex data (when trained correctly) that other models are too simple to fit… The input to a NN contains information about the output hidden inside of it.

Check and double-check to make sure they are working as intended. 23. Check for “frozen” layers or variables. Check if you unintentionally disabled gradient updates for some layers/variables that should be learnable. 24. Increase network size. Maybe the expressive power of your network is not enough to capture the target function.

or the question you asked is "Why neural networks works so well ?" is because of it's hidden units or hidden layers and their representation power. Let me put it this way. You have a logistic regression model and a Neural network which has say 100 neurons each of Sigmoid activation. Now each neuron will be equivalent to one logistic regression.

In recent years, convolutional neural networks (or perhaps deep neural networks in general) have become deeper and deeper, with state-of-the-art networks going from 7 layers to 1000 layers (Residual Nets) in the space of 4 years.The reason behind the boost in performance from a deeper network, is that a more complex, non-linear function can be learned.

Working with Neural Network. The neural network is a weighted graph where nodes are the neurons, and edges with weights represent the connections. It takes input from the outside world and is denoted by x(n). Each input is multiplied by its respective weights, and then they are added. A bias is added if the weighted sum equates to zero, where ...

Neural networks are not "off-the-shelf" algorithms in the way that random forest or logistic regression are. Even for simple, feed-forward networks, the onus is largely on the user to make numerous decisions about how the network is configured, connected, initialized and optimized. This means writing code, and writing code means debugging.

In general, the scale of features in the neural network will also govern their importance. If you have a feature in the output with a large scale then it will generate a larger error compared to other features. Similarly, large scale features in the input will dominate the network and cause larger changes downstream.

UNLABELLED Several papers have been published where nonlinear machine learning algorithms, e.g. artificial neural networks, support vector machines and decision trees, have been used to model the specificity of the HIV-1 protease and extract specificity rules. We show that the dataset used in these studies is linearly separable and that it is a misuse of nonlinear classifiers to apply them to ...

Training a neural network involves using an optimization algorithm to find a set of weights to best map inputs to outputs. The problem is hard, not least because the error surface is non-convex and contains local minima, flat spots, and is highly multidimensional.

Currently, we do not have a good theoretical understanding of how or why neural networks actually work. For example, we know that large neural networks are sufficiently expressive to compute almost any kind of function. Moreover, most functions that fit a given set of training data will not generalise well to new data. And yet, if we train a neural network we will usually obtain a function ...

Why convolutional neural networks work?

Convolutional neural networks work because it's a good extension from the standard deep-learning algorithm. Given unlimited resources and money, there is no need for convolutional because the standard algorithm will also work. However, convolutional is more efficient because it reduces the number of parameters.
