Word2vec is a group of related models that are used to produce word embeddings.These models are shallow, two-layer neural networks that are trained to reconstruct linguistic contexts of words.
It disregards word order (and thus most of syntax or grammar) but captures multiplicity. The bag-of-words model is commonly used in methods of document classification where, for example, the (frequency of) occurrence of each word is used as a feature for training a classifier. [1] It has also been used for computer vision. [2]
A resolution of 1080i produces 59.94 or 50 1920×540 images, each squashed to half-height in the photographic process and stretched back to fill the screen on playback in a television set. The 720p format produces 59.94/50 or 29.97/25 1280×720p images, not squeezed, so that no expansion or squeezing of the image is necessary.
One approach to text simplification is lexical simplification via lexical substitution, a two-step process of first identifying complex words and then replacing them with simpler synonyms. A key challenge here is identifying complex words, which is performed by a machine learning classifier trained on labeled data. Researchers, frustrated by ...
The resolution of 960H depends on whether the equipment is PAL or NTSC based: 960H represents 960 x 576 (PAL) or 960 x 480 (NTSC) pixels. [29] 960H represents an increase in pixels of some 30% over standard D1 resolution, which is 720 x 576 pixels (PAL), or 720 x 480 pixels (NTSC). The increased resolution over D1 comes as a result of a longer ...
A high-speed camera is a device capable of capturing moving images with exposures of less than 1 / 1 000 second or frame rates in excess of 250 frames per second. [1] It is used for recording fast-moving objects as photographic images onto a storage medium.

In the sequence of subspaces, for k>l the space resolution 2 l of the l-th subspace is higher than the resolution 2 k of the k-th subspace. Regularity demands that the model subspace V 0 be generated as the linear hull ( algebraically or even topologically closed ) of the integer shifts of one or a finite number of generating functions ϕ ...
