2 continued physical hazards of machinery and equipment shear points any point where sharp edges of two moving parts move across one another, or where a single sharp part moves with enough speed or force to cut soft material. cutting devices cannot be completely guarded to keep hands and feet out and still perform their intended function.
Sep 28, 2017nbsp018332machine learning is a subfield of artificial intelligence ai. the goal of machine learning generally is to understand the structure of data and fit that data into models that can be understood and utilized by people. although machine learning is a field within computer science, it differs from traditional computational approaches.
Sep 09, 2017nbsp018332central to machine learning is the use of algorithms that can process input data to make predictions and decisions using statistical analysis. thus, instead of manually analyzing data or inputs to develop computing models needed to operate an automated computer, software program, or processes, machine learning systems can automate this entire procedure simply by learning from experience.
Manage machine-intensive operations with real-time oversight. an industry model for an open-pit mine producing 80,000 tons of ore per day estimates the cost of the required machinery to be in excess of 47.5m.1 these high-value assets must be carefully managed to ensure uptime is always optimized, which in turn will maximize production.

While they are two separate presentations, they talk about the same subject- machine learning. the presentations are a summary of the analysis of machine learning adopted by two platforms, netflix and quora. in case of netflix, emphasis has been given to the choice of the right metric and the type of data used for testing and training.

Begin to plan for the development of the mine. this phase of the mining project has several distinct components. 184.108.40.206 construction of access roads the construction of access roads, either to provide heavy equipment and supplies to the mine site or to ship out processed metals and ores, can have substantial environmental impacts,
Usually 45 to 65 percent of the salt is removed. the room height may average 18 feet in a bedded deposit to 100 feet in a dome mine. normally, the first operation is undercutting. large machines cut a slot 10 or more feet in depth across the bottom of a solid salt wall. this leaves a smooth floor for picking up the salt after blasting.
