Field Detail

### DEFAULT_ZERO_TOLERANCE

    public static final double DEFAULT_ZERO_TOLERANCE

  The default zero tolerance.

    Constant Field Values

### POSITIVE_ETA

    public static final double POSITIVE_ETA

  The POSITIVE ETA value. This is specified by the resilient propagation algorithm. This is the percentage by which the deltas are increased by if the partial derivative is greater than zero.

    Constant Field Values

### NEGATIVE_ETA

    public static final double NEGATIVE_ETA

  The NEGATIVE ETA value. This is specified by the resilient propagation algorithm. This is the percentage by which the deltas are increased by if the partial derivative is less than zero.

    Constant Field Values

### DELTA_MIN

    public static final double DELTA_MIN

  The minimum delta value for a weight matrix value.
