The simplest way to generate a callable object for scoring In such cases, you need to generate an appropriate Sometimes because they require additional parameters, such asįbeta_score. Many metrics are not given names to be used as scoring values, Metrics available for various machine learning tasks are detailed in sections The greater_is_better parameter to False ( True by default see the Into a scorer object using make_scorer, set Measuring a prediction error given ground truth and prediction:įunctions ending with _score return a value toįunctions ending with _error or _loss return a
The module trics also exposes a set of simple functions Defining your scoring strategy from metric functions ¶ You can retrieve the names of all available scorers by calling The values listed by the ValueError exception correspond to theįunctions measuring prediction accuracy described in the following The model and the data, like an_squared_error, areĪvailable as neg_mean_squared_error which return the negated value Thus metrics which measure the distance between Scoring parameter the table below shows all possible values.Īll scorer objects follow the convention that higher return values are better Common cases: predefined values ¶įor the most common use cases, you can designate a scorer object with the Model_selection.cross_val_score, take a scoring parameter thatĬontrols what metric they apply to the estimators evaluated. Model selection and evaluation using tools, such as The scoring parameter: defining model evaluation rules ¶ Predictions, see the Pairwise metrics, Affinities and Kernels section. Mean Poisson, Gamma, and Tweedie deviancesįor “pairwise” metrics, between samples and not estimators or R² score, the coefficient of determination Defining your scoring strategy from metric functions The scoring parameter: defining model evaluation rules Metrics and scoring: quantifying the quality of predictions Standing Overnight Repurchase Agreement Facility: A facility to encourage or discourage borrowing above a set rate, which helps to control the effective federal funds rate.Foreign and International Monetary Authorities Repo Facility: A facility for institutions to enter repurchase agreements with the Fed to act as a backstop for liquidity.and participating countries' central banks Central Bank Liquidity Swaps: Established swap lines for central banks from select countries to improve liquidity conditions in the U.S.Term Deposit Facility: Reserve deposits with a term, used to drain reserves from the banking system.Overnight Repurchase Agreement Facility: A supplementary tool used to help control the federal funds rate by selling securities and repurchasing them the next day at a more favorable rate.Interest on Reserve Balances: Encourages banks to hold reserves for liquidity and pays them interest for doing so.Reserve Requirements: Maintaining a reserve to help banks maintain liquidity-reduced to 0% in 2020.Discount Window and Rate: Lending to depository institutions to help banks manage liquidity.Open Market Operations: Purchase and sell securities on the open market to change the supply of reserves.Federal Funds Rate Range: A target range set by the Fed that guides interest rates on overnight lending between depository institutions to boost short-term borrowing.Special indicators: All other economic indicators, such as distribution of personal income, global value chains, healthcare spending, small business well-being, and more.Government indicators: Shows how much the government spends and receives.Employment indicators: Shows employment by industry, state, county, and other areas.Investment in Fixed Assets indicators: Indicate how much capital is tied up in fixed assets.Prices and Inflation indicators: Indicate fluctuations in prices paid for goods and services and changes in currency purchasing power.International Trade and Investment indicators: Indicates the balance of payments between trade partners, how much is traded, and how much is invested internationally.Industry Performance indicators: Measures GDP by industry.Income and Savings indicators: Measures how much consumers make and save.Consumer Spending indicators: Measure how much capital consumers feed back into the economy.Gross Domestic Product indicators: Measure how much the economy produces.
