by Hadoop and Spark, high real-time stream

Tall array is a new mode of operation provided by
Matlab program to cope with big data analysis. tall
array means to represent all the data in the form of
column vector first, to create a long column vector
with one column for each parameter, in the process of
programming algorithm not all the values of the
vector, only the first few data, other data with "? "
This means that these data are not put into memory
during the programming process and the computer
does not know the amount of data in the column array.
In the subsequent calculation, when calling the tall
array, using the algorithm to calculate all the data, the
tall array will be in the form of a stream calculation,
read a section of data, calculate and process this
section of data, and then read the next section of data,
access, read, and process a large collection of data in
sections, until all the tall array data is traversed,
complete the calculation, and summarize the output
of the value requested by the operation command.
When using a single computer, you can use the
Matlab Parallel Computing Toolbox to call multiple
CPUs to process operations simultaneously, and
when processing in a cluster, you can also use the
Cluster Parallel Computing Toolbox, which can
optionally call all available CPUs and memory in the
cluster to process the data, which can greatly improve
the computing power and increase the operation
speed by This can greatly increase computing power
and run more than 3 times faster. (Cui, Ma, Zhang.

Figure 2: Workflow Based on Big Data Artificial
Intelligence Technology
As shown in Figure 2, the workload of the media
is reduced based on big data artificial intelligence
technology, and the work pressure of the writers and
directors is gradually reduced. Especially in the
process of building virtual studios and shaping virtual
characters, the dissemination of programs can be
accomplished by the modular adjustment of
technicians.
4 MEASURES ECOLOGY
CONSTRUCTION MEASURES
UNDER ARTIFICIAL
INTELLIGENCE SYSTEM
4.1 Create High-Quality Intelligent
Content
The creation of high-quality intelligent content can
increase the audience's live experience of the
program and make the audience have a different
program experience. In the process of building text
media content, it can also realize personalized and
accurate content pushing, which meets the interests
of the audience. Therefore, the construction of media
ecology should focus on the creation of high-quality
content and realize the simultaneous innovation and
development of content and technology in the
construction of media ecology.
4.2 Policies to Promote Cross-Border
Integration
In order to further deepen the application of artificial
intelligence in the media field and play its role in the
construction of media ecology, China should create
major projects through policy guidance. The
hardware facilities and software technologies in the
media field have shown the development trend of
continuous development and progress, and the media
ecology is evolving in the direction of technology and
integration, which makes the media field play a
driving role in the perspective of content
dissemination, structure optimization and value
change.
4.3 Improving the Construction of
Laws and Regulations
Although the application of artificial intelligence in
the media field has promoted the development of
media ecology, audiences also question whether there
are ethical and legal issues in the application of data
analysis, personalized recommendation and artificial
intelligence technologies. There is a need to provide
