问题 I am trying to wrap my head around ML and AI using TensorFlow. There is an example problem on the website which discusses the processing of .CSV data. The .CVS data is said to have been taken from the titanic and essentially contains categorical and numerical features that will be used to label a passenger as dead or alive. First of all, if anyone know or has any resources or references that discusses that example in more detail than is done on the TensorFlow website, please could you kindly

问题 If I have a simple 2 level class hierarchy as, for instance, this one: // level 1 class Spare_Part{ private: string name; double price; public: Spare_Part(); string getName() { return name; } double getPrice() { return price; } virtual int getQuantity() { return -1; }; // may also define it as pure virtual }; //level 2 class On_hand : public Spare_Part{ private: int quantity; string location; public: On_hand(); int getQuantity(){ return quantity; } }; I want to have access to the member

问题 I am trying to find methods for specific functions across different packages in R. For example methods(broom::tidy) will return all methods for the function tidy in the package broom . For my current issue it would be better if I could have the methods function in another function like so: f1 <- function(x,y){ methods(x::y) } (I removed other parts of the code that are not relevant to my issue.) However when I run the function like this: f1 <- function(x,y){ methods(x::y)} f1(broom,tidy) I

问题 I am trying to get form data within an Azure function. public static async Task<HttpResponseMessage> Run(HttpRequestMessage req, TraceWriter log) { log.Info("C# HTTP trigger function processed a request."); NameValueCollection col = req.Content.ReadAsFormDataAsync().Result; return req.CreateResponse(HttpStatusCode.OK, "OK"); } I am getting the following error: Exception while executing function: System.Net.Http.Formatting: No MediaTypeFormatter is available to read an object of type

问题 Consider this small snippet of JavaScript: for(var i in map.maps) { buttons.push($("<button>").html(i).click(function() { alert(i); })); } It creates one button for each of the fields in the map.maps object (It's an assoc array). I set the index as the button's text and set it to alert the index as well. Obviously one would expect all the buttons to alert it's own text when clicked, but instead all the buttons alert the text of the final index in the map.maps object when clicked. I assume

问题 I was wondering how could one declare a typed-function array in TypeScript. For instance, say I have a field which can hold a function that has no arguments and returns void: private func: () => void; Now, say I wanted a field which can hold an array of such functions: private funcs: () => void []; This is obviously the wrong way to do what I intended since the compiler considers this to be a function which returns an array of voids. Trying to isolate the inline prototype declaration with
