Dense
Dense layer is the fully connected layer.
Constructor
〔Method 1〕Use units
TSP.layers.Dense( { units: Int } );
〔Method 2〕Use shape
TSP.layers.Dense( { shape : [ Int ] } );

Usage Notes and Examples

units

📦

Int Amount of nodes of FC layer
units = 100
means there are 100 neurals in the fully connect layer

paging

🎨🔧

Bool Enable Pagination, more about paging Since the long 1D layer could make the model hard to visualize, we use paging. true Enable; false [Default] Disable

segmentLength

🎨⚙️

Int Amount of nodes in one page, only take effect when "paging" is enabled 200[Default] 200 nodes in each page

segmentIndex

🎨⚙️

Int The initial start index of first page, only take effect when "paging" is enabled 0[Default]

overview

🎨⚙️

Bool Look layer Text from different angle, more about overview false[Default]

name

🔧

String Name of this layer. Highly recommend to arrange to make code more readable. name: "layerName"

color

⚙️🎨

color format Color of layer Dense default is light green #00ff00

closeButton

⚙️🎨

Dict Close button appearance control dict, more about close button

display : Boolean. true[default] Show button, false Hide button

ratio : Int. Times to normal size, default is 1

For example, 2 means twice the normal size

initStatus

⚙️️🎦

String Layer status at beginning. Open or Close close[default] : Closed at beginning

animeTime

⚙️🎦

Int The speed of open and close animation For example, 2000 means 2 seconds. Note: Configure animeTime in a specific layer will override model's animeTime configuration.
Properties
.inputShape : Int[]
filter_center_focusThe shape of input tensor, for example inputShape = [ 28, 28, 3 ] represents 3 feature maps and each one is 28 by 28.
filter_center_focusAfter model.init() data is available, otherwise is undefined.
.outputShape : Int[]
filter_center_focusThe shape of output tensor is 1-dimensional. 1️⃣
filter_center_focusThe shape of output tensor. For example outputShape = [ 1000 ] represents the output through this layer has 1000 outputs.
filter_center_focusAfter model.init() data is available, otherwise is undefined.
.neuralValue : Float[]
filter_center_focusThe intermediate raw data after this layer.
filter_center_focusAfter load and model.predict() data is available, otherwise is undefined.
.name : String
filter_center_focusThe custom name for this layer.
filter_center_focusOnce created, you can get it.
.layerType : String
filter_center_focusType of this layer, return a constant: string Dense.
filter_center_focusOnce created, you can get it.
Method
filter_center_focusThis method only used in Functional Model (Non-sequential, Graph structure).
filter_center_focusLink this layer to layer which is the previous layer.
filter_center_focusTo crete a link between this layer and the previous layer. You don't need to use this method specifically to create links in Sequential Model; Instead, you can simply add layers along the lines of Keras or TensorFlow.js build the model syntax.
let inputLayer = new TSP.layers.GreyscaleInput( {

    shape: [28, 28]

} );

let denseLayer = new TSP.layers.Dense( {

    unit: 1000

} );

denseLayer.apply( inputLayer );
.openLayer() : void
filter_center_focusClick on the layer directly to open it by interacting directly with the object in the 3D scene.
filter_center_focusIn code, calling the method to open it.
let denseLayer = new TSP.layers.Dense( {

    // configure some parameters for Dense.

} );

model.add( denseLayer );

// ... add more layers for model.

model.init();

// Call openLayer API to open layer.

denseLayer.openLayer();
filter_center_focusTo close by interacting directly with objects in a 3D scene by clicking the close button.
filter_center_focus In code, calling the method to close it.
let denseLayer = new TSP.layers.Dense( {

    // configure some parameters for Dense.

} );

model.add( denseLayer );

// ... add more layers for model.

model.init();

// If this layer already opened, call closeLayer API to close layer.

denseLayer.closeLayer();
Example
filter_center_focus Declare an instance of Dense to facilitate reuse
let denseLayer = new TSP.layers.Dense( {

    units: 1000,
    name: "Dense1",
    initStatus: "open"

} );

model.add( denseLayer );
filter_center_focusAdd Dense directly
model.add( new TSP.layers.Dense( {

    units: 1000,
    name: "Dense2"

} ) );
Use Case
When you add fully connect layer with Keras | TensorFlow | tfjs in your model the corresponding API is Dense in TensorSpace.

⭐️ Required Must be provided, cannot be empty. Meanwhile constructor works properly if this arguments provided. Control arguments use default value.
🔧 Suggest Recommended for giving. The API can work without them.
⚙️ Optional As an auxiliary adjustment parameter when used, selectively added according to the specific situation The parameters here have no effect on the structure of the layer (3D visualized form).
📦 Model Configure the properties of the Layer. It changes the output shape.
🎨 Style Override the properties in TSP.model (model configuration)
