Is neural network important for data science?
The data scientist doesn’t have to program the neural network with characteristics to distinguish between dogs and cats; the neural network learns to distinguish the most important features itself. A neural network can learn to classify any data with a label that correlates to information the network can analyze.
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.
Can neural network model any function?
No, there are no specific functions that a neural network cannot approximate. However, there are some important caveats: Neural networks do not encode the actual functions, only numeric approximations.
Are neural networks hard to learn?
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.
How does neural network solve computational problems?
Artificial neural networks are a form of machine-learning algorithm with a structure roughly based on that of the human brain. Like other kinds of machine-learning algorithms, they can solve problems through trial and error without being explicitly programmed with rules to follow.
Can neural networks learn by themselves?
Neural networks generally perform supervised learning tasks, building knowledge from data sets where the right answer is provided in advance. The networks then learn by tuning themselves to find the right answer on their own, increasing the accuracy of their predictions.
Can a neural network multiply?
As a composition of Lischitz continuous functions, neural network is also Lipschitz continuous, but multiplication is not Lipschitz continuous. This means that neural network cannot approximate multiplication when one of the x or y goes too large.
