Convert data to vectors
To turn information into lists of numbers so a computer model can use it.
Mẫu sử dụng:
vectorize [data/text/documents/features]
Lỗi thường gặp:
Do not use vectorize for any kind of digitizing; the result must be a vector or vector-like numerical representation.
Từ đồng nghĩa
encode (broader; means convert into a coded form, not necessarily a vector)
|
embed (often means convert into a dense vector representation in machine learning)
|
featurize (means convert raw data into model features, usually but not always as vectors)
Từ trái nghĩa
devectorize (rare; means convert from a vector representation back to a non-vector form)
|
decode (broader; means convert an encoded representation back into a more usable or understandable form)

Make code use vector operations
To make code run operations on many values at the same time instead of one by one.
Mẫu sử dụng:
vectorize [code/a loop/a function/a calculation]
Lỗi thường gặp:
Vectorize does not simply mean to use a variable called a vector; it usually means changing how the computation is performed.
Từ đồng nghĩa
parallelize (broader; may use multiple cores or tasks, not specifically vector operations)
|
optimize (broader; can mean improve performance in many different ways)
|
rewrite (less specific; means change the code, not necessarily for vector operations)
Từ trái nghĩa
scalarize (means convert vector operations into scalar, one-value-at-a-time operations)
|
de-vectorize (means remove vectorized processing or rewrite it as non-vector code)

Convert image to vector graphics
To turn a normal pixel image into a vector image that can be resized without becoming blurry.
Mẫu sử dụng:
vectorize [an image/a logo/a drawing/artwork]
Lỗi thường gặp:
Do not confuse vectorize with rasterize; rasterize means convert vector graphics into pixels, usually the opposite direction.
Từ đồng nghĩa
trace (in graphics, often means create vector outlines from an image, either manually or automatically)
|
convert to vector (more explicit and common in nontechnical design instructions)
|
outline (can mean convert text or shapes into editable outlines, but is narrower)
Từ trái nghĩa
rasterize (means convert vector graphics into a pixel-based image)

Reshape into one vector
To turn a matrix or array into one long list of numbers in a fixed order.
Mẫu sử dụng:
vectorize [a matrix/an array/a tensor]
Lỗi thường gặp:
In mathematics and data work, specify row-wise or column-wise order if the order matters.
Từ đồng nghĩa
flatten (common in programming; means make an array one-dimensional, often less formally)
|
reshape (broader; can change data into many shapes, not only a vector)
|
stack (describes one common method of making a vector from rows or columns)
Từ trái nghĩa
unflatten (means restore a one-dimensional structure to a higher-dimensional shape)
|
reshape (can be the reverse when changing a vector back into a matrix or array)
