Before you start reconsidering your career choices, you might want to talk to students based in Atlanta David Antzelevich. Utilizing what he learned in the Thinkful data science program, it uses machine learning and natural language processing to read, interpret, and analyze it for you. To complete your analysis, David first must prepare the text to read the computer Humans and computers read differently. We can easily see that “BA,” “BS,” “scholars” and “scholars” all refer to similar types of degrees. Computers, on the other hand, will read this all as different terms. Before the computer can read text, David must clean it a little.
To do this, David uses regular expressions to stand different spelling and produce good and clean text ready for computer processing. After he finished tidying, David built a unattended learning model to classify sentences into different categories (such as information about the company, description of ideal candidates, and descriptions of roles and responsibilities, etc.) To do this, David uses the Word2VEC NLTK algorithm. This algorithm employs a dictionary and vector to identify similar words. For example, it can connect one type of data science technology and quickly find all other types of technologies mentioned in the text.

This is one of the most interesting and evolving scientific aspects of the data. These intelligent machines can process data fed and use it to learn, adapt, and make decisions, replicate the human brain to some extent. For example, self-driving cars use data from various sources to make decisions about speed, round, and pass other people while on the road.
* Large data – As internet connectivity throughout the world increases, more data is produced every second. Large data refers to large quantities of data produced at high speed and exponential levels. The potential of science has increased rapidly because of large data.
* Analytics behavior – behavioral analytics use data to understand why and how consumers act in a certain way. Understanding consumer behavior using data allows businesses to predict their actions in the future. This prediction further helps businesses or data scientists in achieving favorable results.
