What is neural network and its advantages?
Advantages of Neural Networks:
Neural Networks have the ability to learn by themselves and produce the output that is not limited to the input provided to them. The input is stored in its own networks instead of a database, hence the loss of data does not affect its working.
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.
What are the pros and cons of decision tree?
Decision tree learning pros and cons
- Easy to understand and interpret, perfect for visual representation. …
- Can work with numerical and categorical features.
- Requires little data preprocessing: no need for one-hot encoding, dummy variables, and so on.
- Non-parametric model: no assumptions about the shape of data.
What are the advantages and disadvantages of decision trees?
Advantages and Disadvantages of Decision Trees in Machine Learning. Decision Tree is used to solve both classification and regression problems. But the main drawback of Decision Tree is that it generally leads to overfitting of the data.
What are the advantages of neural network in AI?
There are various advantages of neural networks, some of which are discussed below:
- Store information on the entire network. …
- The ability to work with insufficient knowledge: …
- Good falt tolerance: …
- Distributed memory: …
- Gradual Corruption: …
- Ability to train machine: …
- The ability of parallel processing:
What is a disadvantage of a network?
Purchasing the network cabling and file servers can be expensive. There is a danger of hacking , particularly with wide area networks. … Security procedures are needed to prevent such abuse, eg a firewall .
What is advantage and dis advantage of back propagation neural network?
Backpropagation is fast, simple and easy to program. It has no parameters to tune apart from the numbers of input. It is a flexible method as it does not require prior knowledge about the network. It is a standard method that generally works well.
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.
What is the importance of neural network?
Neural networks reflect the behavior of the human brain, allowing computer programs to recognize patterns and solve common problems in the fields of AI, machine learning, and deep learning.
Why is neural network better than decision tree?
Neural networks are often compared to decision trees because both methods can model data that has nonlinear relationships between variables, and both can handle interactions between variables. … A neural network is more of a “black box” that delivers results without an explanation of how the results were derived.
What kind of problems can neural networks solve?
Their strength lies in their ability to make sense out of complex, noisy, or nonlinear data. 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 issue with neural network?
Another trouble which is encountered in neural networks, especially when they are deep is internal covariate shift. The statistical distribution of the input keeps changing as training proceeds. This can cause a significant change in the domain and hence, reduce training efficiency.
What are the problems for neural network learning?
Appropriate Problems for NN Learning
The target function output may be discrete-valued, real-valued, or a vector of several real-valued or discrete-valued attributes. The training examples may contain errors. Long training times are acceptable. Fast evaluation of the learned target function may be required.
