immuneML.encodings.kmer_frequency.sequence_encoding.GappedKmerSequenceEncoder module

class immuneML.encodings.kmer_frequency.sequence_encoding.GappedKmerSequenceEncoder.GappedKmerSequenceEncoder

Bases: SequenceEncodingStrategy

static encode_sequence(sequence: ReceptorSequence, params: EncoderParams)

creates all overlapping gapped k-mers from a sequence as features for use in KmerFrequencyEncoder. this gap length goes from min_gap to max_gap inclusive, and there is a k-mer of length k_left on the left side of the gap and a k-mer of length k_right on the right side of the gap. :param sequence: ReceptorSequence :param params: EncoderParams (within the “model”, the following keys are used: “k_left”, “k_right”, “max_gap”,

“min_gap”)

Returns:

SequenceEncodingResult

static get_feature_names(params: EncoderParams)

immuneML.encodings.kmer_frequency.sequence_encoding.IMGTGappedKmerEncoder module

class immuneML.encodings.kmer_frequency.sequence_encoding.IMGTGappedKmerEncoder.IMGTGappedKmerEncoder

Bases: SequenceEncodingStrategy

static encode_sequence(sequence: ReceptorSequence, params: EncoderParams)

creates all overlapping gapped k-mers and IMGT position pairs from a sequence as features for use in KmerFrequencyEncoder. this gap length goes from min_gap to max_gap inclusive, and there is a k-mer of length k_left on the left side of the gap and a k-mer of length k_right on the right side of the gap. :param sequence: ReceptorSequence :param params: EncoderParams (within the “model”, the following keys are used: “k_left”, “k_right”, “max_gap”,

“min_gap”)

Returns:

SequenceEncodingResult

immuneML.encodings.kmer_frequency.sequence_encoding.IMGTKmerSequenceEncoder module

class immuneML.encodings.kmer_frequency.sequence_encoding.IMGTKmerSequenceEncoder.IMGTKmerSequenceEncoder

Bases: SequenceEncodingStrategy

static encode_sequence(sequence: ReceptorSequence, params: EncoderParams)

creates overlapping continuous k-mers from a sequence as features for use in KmerFrequencyEncoder object of type EncoderParams, same object as passed into KmerFrequencyEncoder :param sequence: ReceptorSequence :param params: EncoderParams (where params[“model”][“k”] is used) :return: SequenceEncodingResult consisting of features and feature information names

static get_feature_names(params: EncoderParams)

immuneML.encodings.kmer_frequency.sequence_encoding.IdentitySequenceEncoder module

class immuneML.encodings.kmer_frequency.sequence_encoding.IdentitySequenceEncoder.IdentitySequenceEncoder

Bases: SequenceEncodingStrategy

static encode_sequence(sequence: ReceptorSequence, params: EncoderParams)

Encodes a ReceptorSequence based on information from within the ReceptorSequence and SequenceMetadata instances. This allows for looking at frequency for whole sequences, with flexible definition of what a unique whole sequence is. :param sequence: ReceptorSequence :param params: EncoderParams (params[“model”][“sequence”] and params[“model”][“metadata_fields_to_include”] are

used)

Returns:

list with only single feature

static get_feature_names(params: EncoderParams)

immuneML.encodings.kmer_frequency.sequence_encoding.KmerSequenceEncoder module

class immuneML.encodings.kmer_frequency.sequence_encoding.KmerSequenceEncoder.KmerSequenceEncoder

Bases: SequenceEncodingStrategy

static encode_sequence(sequence: ReceptorSequence, params: EncoderParams)

Encodes a receptor sequence into a sequence of k-mers

Parameters:

• sequence – ReceptorSequence object

• params – EncoderParams object with information on k-mer length

Returns:

static get_feature_names(params: EncoderParams)
