Frequent question: Which are weaknesses of a neural network algorithm?

What is the weakness of neural network?

Disadvantages include its “black box” nature, greater computational burden, proneness to overfitting, and the empirical nature of model development. An overview of the features of neural networks and logistic regression is presented, and the advantages and disadvantages of using this modeling technique are discussed.

Which of the following is a major disadvantage of using a neural network?

Arguably, the best-known disadvantage of neural networks is their “black box” nature. Simply put, you don’t know how or why your NN came up with a certain output.

What are advantages and disadvantages of neural networks?

Ability to train machine: Artificial neural networks learn events and make decisions by commenting on similar events.

  • Hardware dependence: Artificial neural networks require processors with parallel processing power, by their structure. …
  • Unexplained functioning of the network: This is the most important problem of ANN.

What is not a good application of neural networks?

Example: Banks generally will not use Neural Networks to predict whether a person is creditworthy because they need to explain to their customers why they denied them a loan. Long story short, when you need to provide an explanation to why something happened, Neural networks might not be your best bet.

What are the disadvantages in using a neural network to build a supervised model?

Cons

  • Neural networks are black boxes, meaning we cannot know how much each independent variable is influencing the dependent variables.
  • It is computationally very expensive and time consuming to train with traditional CPUs.
  • Neural networks depend a lot on training data.

What kind of problems can neural networks solve?

Neural networks can provide robust solutions to problems in a wide range of disciplines, particularly areas involving classification, prediction, filtering, optimization, pattern recognition, and function approximation.

What is the biggest problem with neural networks?

The very most disadvantage of a neural network is its black box nature. Because it has the ability to approximate any function, study its structure but don’t give any insights on the structure of the function being approximated.

Is neural Network difficult?

Training deep learning neural networks is very challenging. The best general algorithm known for solving this problem is stochastic gradient descent, where model weights are updated each iteration using the backpropagation of error algorithm. Optimization in general is an extremely difficult task.

What kind of problems do artificial neural networks handle?

Researchers are designing artificial neural networks (ANNs) to solve a variety of problems in pattern recognition, prediction, optimization, associative memory, and control.

What are the drawbacks of fuzzy logic and neural networks?

A major drawback of Fuzzy Logic control systems is that they are completely dependent on human knowledge and expertise. You have to regularly update the rules of a Fuzzy Logic control system. These systems cannot recognize machine learning or neural networks.

What is the limitation of Perceptron?

Perceptron networks have several limitations. First, the output values of a perceptron can take on only one of two values (0 or 1) due to the hard-limit transfer function. Second, perceptrons can only classify linearly separable sets of vectors.

What is the disadvantage of deep learning?

Main disadvantages: It requires very large amount of data in order to perform better than other techniques. It is extremely expensive to train due to complex data models.
