**Explain BIG DATA:** As this has become a popular marketing buzz phrase, definitions have proliferated, but in general, it refers to the ability to work with collections of data that had been impractical before because of their volume, velocity, and variety (“the three Vs”). A key driver of this new ability has been easier distribution of storage and processing across networks of inexpensive commodity hardware using technology such as Hadoop instead of requiring larger, more powerful individual computers. The work done with these large amounts of data often draws on data science skills..

Different definitions in web development like **Big Data** in Dictionary B.

- Manual Backpropagation:
- Meaning algorithm for iteratively adjusting the weights used in a neural network system. Backpropagation is often used to implement gradient descent. See also neural network, gradient descent big data definition.
- Manual Bias:
- Meaning “bias is a learner’s tendency to consistently learn the same wrong thing. Variance is the tendency to learn random things irrespective of the real signal.... It’s easy to avoid overfitting big data explain.
- Manual Binomial Distribution:
- Meaning outcomes of independent events with two mutually exclusive possible outcomes, a fixed number of trials, and a constant probability of success. This is a discrete probability distribution, as opposed big data what is.
- Manual Bayesian Network:
- Meaning “Bayesian networks are graphs that compactly represent the relationship between random variables for a given problem. These graphs aid in performing reasoning or decision making in the face of big data meaning.
- Manual Bayes' Theorem:
- Meaning Rule. An equation for calculating the probability that something is true if something potentially related to it is true. If P(A) means “the probability that A is true” and P(A|B) means “the big data abbreviation.
