A training data set is a data set of examples used during the learning process and is used to fit the parameters (e.g., weights) of, for example, a classifier. [9] [10]For classification tasks, a supervised learning algorithm looks at the training data set to determine, or learn, the optimal combinations of variables that will generate a good predictive model. [11]
The difference between data analysis and data mining is that data analysis is used to test models and hypotheses on the dataset, e.g., analyzing the effectiveness of a marketing campaign, regardless of the amount of data. In contrast, data mining uses machine learning and statistical models to uncover clandestine or hidden patterns in a large ...
Text mining, text data mining (TDM) or text analytics is the process of deriving high-quality information from text.It involves "the discovery by computer of new, previously unknown information, by automatically extracting information from different written resources."
A requirement is that both the system data and model data be approximately Normally Independent and Identically Distributed (NIID). The t-test statistic is used in this technique. If the mean of the model is μ m and the mean of system is μ s then the difference between the model and the system is D = μ m - μ s .
Process mining is a family of techniques for analyzing event data to understand and improve operational processes. Part of the fields of data science and process management, process mining is generally built on logs that contain case id, a unique identifier for a particular process instance; an activity, a description of the event that is occurring; a timestamp; and sometimes other information ...
The Grasberg mine has been cited as one of the largest single taxpayers in Indonesia, [3] [17] contributing 0.6 percent to Indonesia's GDP (96 percent of the GDP of Mimika Regency where the mine is located) and generating 17.3 billion USD in revenue for the Indonesian government between 1992 and 2017 through taxes, export duties, royalties, and ...
Nickel mining in Sulawesi. Nickel mining in Indonesia began with small-scale exploratory mining operations during the Dutch East Indies era and began to expand in the 1960s. . Most of Indonesia's proven nickel reserves are located in the islands of Sulawesi and Halmahera, and the country has the largest annual production and reserves of nickel in the wor
