flatten

问题 I am trying to train ANN model on my sound data set, which has 320 rows and 50 columns, while running this code: Model= Sequential([ Flatten(), Dense(16, input_shape=(1,50), activation= 'relu' ) , Dense(32, activation= 'relu' ), Dense(2, activation='softmax' ) , ]) Model.compile(Adam(lr=0.0001), loss='sparse_categorical_crossentropy', metrics=['accuracy']) Model.fit(S_T_S, T_L, validation_split=0.1, batch_size=20, epochs=20, shuffle='true', verbose=2) I am getting error of: Input 0 is

问题 I have the following array: Array ( [0] => Array ( [id] => 2 [title] => Root 2 [description] => [site_id] => 1 [parent_id] => 0 [created_at] => [updated_at] => [children] => Array ( [0] => Array ( [id] => 4 [title] => Child 2 [description] => [site_id] => 1 [parent_id] => 2 [created_at] => [updated_at] => [children] => Array ( [0] => Array ( [id] => 6 [title] => Child 4 [description] => [site_id] => 1 [parent_id] => 4 [created_at] => [updated_at] => ) ) ) ) ) [2] => Array ( [id] => 7 [title]

问题 The goal is to eliminate all inner parenthesis. (flatten '(a (b c) d)) becomes '(a b c d) This is my code in Racket ; if slist is null, return empty ; otherwise, if it is a pair, recursively solve car and cdr and concat them ; if it is a symbol, return the symbol (define flatten (lambda (slist) (cond [ (null? slist) '()] [ (pair? slist) (cons ((flatten (car slist)) (flatten (cdr slist))))] [ (symbol? slist) slist]))) It's complaining procedure application: expected procedure, given: c;

问题 I want to flatten an object like this... var obj1 = { firstName: 'John', lastName: 'Green', car: { make: 'Honda', model: 'Civic', revisions: [ { miles: 10150, code: 'REV01', changes: }, { miles: 20021, code: 'REV02', changes: [ { type: 'asthetic', desc: 'Left tire cap' }, { type: 'mechanic', desc: 'Engine pressure regulator' } ] } ] }, visits: [ { date: '2015-01-01', dealer: 'DEAL-001' }, { date: '2015-03-01', dealer: 'DEAL-002' } ] }; ... into a daisy chain form like the following: {

问题 I am trying to compute a panoramic projection for dental imaging purpose. I have a rectangle surface "curved" in one direction by a piecewise function. If we look at it from the top, it looks like a regular piecewise function. The "piecewise linear function" is just defined by a set of 3D points. All the points are in the same plane. The plane where all the 3D points sit is orthogonal to the curved surface (see the green line in the top-left window) I am looking for the proper way to "flatten

问题 In short, I'm having issues specifically "flattening" stamp comments in PDF's while using Itextsharp. The effect I'm looking for is identical to what you get when you "print to PDF" from Acrobat (the stamp can no longer be moved/edited/etc. but you can still select any text it might have). Using some very simple Javascript code also seems to work just fine (this.flattenPages). This problems seems to specifically pertain to stamps, which is the real trick of it. I've successfully used the

问题 I'm trying to flatten a recursive structure but I'm having trouble with recursive iterators. Here's what the struct looks like: #[derive(Debug, Clone)] pub struct C { name: String, vb: Option<Vec<B>>, } #[derive(Debug, Clone)] pub struct B { c: Option<C>, } #[derive(Debug, Clone)] pub struct A { vb: Option<Vec<B>>, flat_c: Option<Vec<C>>, } My plan is to traverse the vb vector and flatten it into flat_c . I want it to look like this, or at least, be a Vec<String> : Some([ C { name: "foo", vb:

问题 I have the following code that flattens a multidimensional array var x = [[[2, 3], 4], 5, [6, 7]]; function flatten(arr) { for (var i = 0; i < arr.length; i++) { if (arr[i].constructor === Array) { subArr = arr[i]; // Shift the array down based on the space needed for the sub array for (var j = arr.length + subArr.length - 2; j > i + subArr.length - 1; j--) { arr[j] = arr[j - subArr.length + 1]; } // Insert sub array elements where they belong for (var k = 0; k < subArr.length; k++) { arr[i +

问题 I want to unflatten an object like this... var obj2 = { "firstName": "John", "lastName": "Green", "car.make": "Honda", "car.model": "Civic", "car.revisions.0.miles": 10150, "car.revisions.0.code": "REV01", "car.revisions.0.changes": "", "car.revisions.1.miles": 20021, "car.revisions.1.code": "REV02", "car.revisions.1.changes.0.type": "asthetic", "car.revisions.1.changes.0.desc": "Left tire cap", "car.revisions.1.changes.1.type": "mechanic", "car.revisions.1.changes.1.desc": "Engine pressure

问题 If I have a func like this: func AcceptsAnything(v ...interface{}){ args =: FlattenDeep(v); // flatten any arrays or slices } I am trying to implement FlattenDeep: func getKind(v interface{}) string { rt := reflect.TypeOf(v) switch rt.Kind() { case reflect.Slice: return "slice" case reflect.Array: return "array" default: return "unknown" } } func FlattenDeep(args ...interface{}) []interface{} { list := []interface{}{} for _, v := range args { kind := getKind(v); if kind != "unknown" { list =
