  2. One-hot - Wikipedia

    en.wikipedia.org/wiki/One-hot

    One-hot encoding is often used for indicating the state of a state machine.When using binary, a decoder is needed to determine the state. A one-hot state machine, however, does not need a decoder as the state machine is in the nth state if, and only if, the nth bit is high.

  3. Feature hashing - Wikipedia

    en.wikipedia.org/wiki/Feature_hashing

    One-hot encoding is easy to interpret, but it requires one to maintain the arbitrary enumeration of . Given a token t ∈ T {\displaystyle t\in T} , to compute ϕ ( t ) {\displaystyle \phi (t)} , we must find out the index i {\displaystyle i} of the token t {\displaystyle t} .

    en.wikipedia.org/wiki/LightGBM

    Exclusive feature bundling (EFB) is a near-lossless method to reduce the number of effective features. In a sparse feature space many features are nearly exclusive, implying they rarely take nonzero values simultaneously. One-hot encoded features are a perfect example of exclusive features.

  5. Dummy variable (statistics) - Wikipedia

    en.wikipedia.org/wiki/Dummy_variable_(statistics)

    In this case, multiple dummy variables would be created to represent each level of the variable, and only one dummy variable would take on a value of 1 for each observation. Dummy variables are useful because they allow us to include categorical variables in our analysis, which would otherwise be difficult to include due to their non-numeric ...

  6. State encoding for low power - Wikipedia

    en.wikipedia.org/wiki/State_encoding_for_low_power

    For such FSM, one-hot encoding guarantees switching of two bits for every state change. But since the number of state variables needed is equal to the number of states, as states increase, one-hot encoding becomes an impractical solution, mainly because with an increased number of inputs and outputs to the circuit, complexity and capacitive ...

    An example is dual rail encoding, and chain link [4] used in delay insensitive circuits. For these codes, =, =, = and (,,) =. Some of the more notable uses of one-hot codes include biphase mark code uses a 1-of-2 code; pulse-position modulation uses a 1-of-n code; address decoder, etc.

  9. Feature (machine learning) - Wikipedia

    en.wikipedia.org/wiki/Feature_(machine_learning)

    Examples of categorical features include gender, color, and zip code. Categorical features typically need to be converted to numerical features before they can be used in machine learning algorithms. This can be done using a variety of techniques, such as one-hot encoding, label encoding, and ordinal encoding.
