Detecting significant changes in data
c#,algorithm,data,graph,statistics
A simple way is to calculate the difference between every two neighbouring samples, eg diff= abs(y[x point 1] - y[x point 0]) and calculate the standard deviation for all the differences. This will rank the differences in order for you and also help eliminate random noise which you get if...
How to store simple text data in the python program itself? [closed]
For basics, you should check out the JSON library from Python: https://docs.python.org/2/library/json.html Here's a quick example: >>> import json # grabs config.json in same directory as python file >>> with open("config.json", "r") as e: ... myconfig = json.load(e) >>> print myconfig {u'4': u'5', u'6': 7} # dump to string representation...
parsing JSON files in python to get specific values
Json.loads will also decode that dictionary. So to access cpu_count for example it would be json_data["Hosts"]["cpu_count"]. The json library will turn everything into a standard python data type (dict, list, int, str) or from those data type into a json readable format. You can also define a parser to parse...
