  2. Fraction of variance unexplained - Wikipedia

    In this case, no variation in Y can be accounted for, and the FVU then has its maximum value of 1. More generally, the FVU will be 1 if the explanatory variables X tell us nothing about Y in the sense that the predicted values of Y do not covary with Y. But as prediction gets better and the MSE can be reduced, the FVU goes down.

    en.wikipedia.org/wiki/Tax_deduction_at_source

    Tax deduction at source (TDS) has come into existence with the motive of collecting tax from different sources of income. As per this concept, a person (Payer) who is responsible to make payment of specified nature to any other person (Payee) shall deduct tax at source before making payment to such person (Payee) and remit the same into the account of the Central Government.

    A training data set is a data set of examples used during the learning process and is used to fit the parameters (e.g., weights) of, for example, a classifier. [9] [10]For classification tasks, a supervised learning algorithm looks at the training data set to determine, or learn, the optimal combinations of variables that will generate a good predictive model. [11]

    en.wikipedia.org/wiki/Product_data_management

    Product data management is the use of software or other tools to track and control data related to a particular product. The data tracked usually involves the technical specifications of the product, specifications for manufacture and development, and the types of materials that will be required to produce goods.

    Errors in encoding and decoding between text and representations can cause hallucinations. When encoders learn the wrong correlations between different parts of the training data, it could result in an erroneous generation that diverges from the input. The decoder takes the encoded input from the encoder and generates the final target sequence.

  8. Return-oriented programming - Wikipedia

    en.wikipedia.org/wiki/Return-oriented_programming

    Li et al. claimed that "our return indirection technique essentially de-generalizes return-oriented programming back to the old style of return-into-libc." [ 24 ] Their proof-of-concept compiler included a peephole optimization phase to deal with "certain machine instructions which happen to contain the return opcode in their opcodes or ...

  9. Simple file verification - Wikipedia

    en.wikipedia.org/wiki/Simple_file_verification

    Simple file verification (SFV) is a file format for storing CRC32 checksums of files to verify the integrity of files. SFV is used to verify that a file has not been corrupted, but it does not otherwise verify the file's authenticity. The .sfv file extension is usually used for SFV files. [1]
