class trajdl.datasets.base.locseq.LocSeq(seq: Any, entity_id: str | None = None, ts_seq: List[int] | None = None, ts_delta: List[float] | None = None, dis_delta: List[float] | None = None, start_ts: int | None = None)

Bases: BaseSeq

Location sequence representation.

loc_seq

The list of locations in the sequence.

Type:

List[str]

entity_id

An optional identifier, which can store the sequence ID or user ID.

Type:

Union[str, None]

ts_seq

A sequence of timestamps (in seconds or milliseconds), defined by the user without constraints.

Type:

Union[List[int], None]

static check_seq(seq: Any) → List[str]

Check if the sequence is valid.

Parameters:

seq (Any) – The sequence to be checked.

Returns:

The validated location sequence.

Return type:

List[str]

Raises:

ValueError – If seq is not a List[str].

property d: str

Return the destination location.

property o: str

Return the starting location.
