Convert data to vectors
To turn information into lists of numbers so a computer model can use it.
用法模式：
vectorize [data/text/documents/features]
常见错误：
Do not use vectorize for any kind of digitizing; the result must be a vector or vector-like numerical representation.
近义词
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)
反义词
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)
搭配
vectorize text
|vectorize documents
|vectorize a corpus
|vectorize features
|vectorize input data
|vectorize search queries
|vectorize customer reviews
|automatically vectorize data
|vectorized representation
|text vectorizer

例句
- Before training the classifier, the team vectorized thousands of product reviews.
- The app vectorizes each search query so it can compare meanings, not just keywords.

Make code use vector operations
To make code run operations on many values at the same time instead of one by one.
用法模式：
vectorize [code/a loop/a function/a calculation]
常见错误：
Vectorize does not simply mean to use a variable called a vector; it usually means changing how the computation is performed.
近义词
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)
反义词
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)
搭配
vectorize code
|vectorize a loop
|vectorize a function
|vectorize calculations
|vectorize operations
|vectorize a kernel
|automatically vectorize
|fully vectorize
|vectorized implementation
|compiler vectorizes

例句
- Replacing the loop with a NumPy expression vectorized the calculation and cut the run time in half.
- Modern compilers can vectorize some loops automatically when the iterations are independent.
- She vectorized the image-processing code to use the CPU's SIMD instructions.
学习者例句

Convert image to vector graphics
To turn a normal pixel image into a vector image that can be resized without becoming blurry.
用法模式：
vectorize [an image/a logo/a drawing/artwork]
常见错误：
Do not confuse vectorize with rasterize; rasterize means convert vector graphics into pixels, usually the opposite direction.
近义词
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)
反义词
rasterize (means convert vector graphics into a pixel-based image)
搭配
vectorize an image
|vectorize a logo
|vectorize artwork
|vectorize a sketch
|vectorize a drawing
|vectorize a bitmap
|vectorize a raster file
|auto-vectorize a design
|vectorized logo

Reshape into one vector
To turn a matrix or array into one long list of numbers in a fixed order.
用法模式：
vectorize [a matrix/an array/a tensor]
常见错误：
In mathematics and data work, specify row-wise or column-wise order if the order matters.
近义词
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)
反义词
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)
搭配
