| Public Member Functions inherited from Encoder | |
| def | getWidth |
| Should return the output width, in bits. More... | |
| def | encodeIntoArray |
| Encodes inputData and puts the encoded value into the numpy output array, which is a 1-D array of length returned by getWidth(). More... | |
| def | setLearning |
| Set whether learning is enabled. More... | |
| def | setFieldStats |
| This method is called by the model to set the statistics like min and max for the underlying encoders if this information is available. More... | |
| def | encode |
| Convenience wrapper for encodeIntoArray. More... | |
| def | getScalarNames |
| Return the field names for each of the scalar values returned by getScalars. More... | |
| def | getDecoderOutputFieldTypes |
| Returns a sequence of field types corresponding to the elements in the decoded output field array. More... | |
| def | setStateLock |
| Setting this to true freezes the state of the encoder This is separate from the learning state which affects changing parameters. More... | |
| def | getEncoderList |
| def | getScalars |
| Returns a numpy array containing the sub-field scalar value(s) for each sub-field of the inputData. More... | |
| def | getEncodedValues |
| Returns the input in the same format as is returned by topDownCompute(). More... | |
| def | getBucketIndices |
| Returns an array containing the sub-field bucket indices for each sub-field of the inputData. More... | |
| def | scalarsToStr |
| Return a pretty print string representing the return values from getScalars and getScalarNames(). More... | |
| def | getDescription |
| This returns a list of tuples, each containing (name, offset). More... | |
| def | getFieldDescription |
| Return the offset and length of a given field within the encoded output. More... | |
| def | encodedBitDescription |
| Return a description of the given bit in the encoded output. More... | |
| def | pprintHeader |
| Pretty-print a header that labels the sub-fields of the encoded output. More... | |
| def | pprint |
| Pretty-print the encoded output using ascii art. More... | |
| def | decode |
| Takes an encoded output and does its best to work backwards and generate the input that would have generated it. More... | |
| def | decodedToStr |
| Return a pretty print string representing the return value from decode(). | |
| def | getBucketValues |
| Returns a list of items, one for each bucket defined by this encoder. More... | |
| def | getBucketInfo |
| Returns a list of EncoderResult namedtuples describing the inputs for each sub-field that correspond to the bucket indices passed in 'buckets'. More... | |
| def | topDownCompute |
| Returns a list of EncoderResult namedtuples describing the top-down best guess inputs for each sub-field given the encoded output. More... | |
| def | closenessScores |
| Compute closeness scores between the expected scalar value(s) and actual scalar value(s). More... | |
| def | getDisplayWidth |
| Calculate width of display for bits plus blanks between fields. More... | |
| def | formatBits |
| Copy one array to another, inserting blanks between fields (for display) If leftpad is one, then there is a dummy value at element 0 of the arrays, and we should start our counting from 1 rather than 0. More... | |
This is an implementation of a delta encoder.
The delta encoder encodes differences between successive scalar values instead of encoding the actual values. It returns an actual value when decoding and not a delta.
