Dense
Dense layer is the fully connected layer.
Constructor
Based on whether TensorSpace Model load a pre-trained model before initialization, configure Layer in different ways. Checkout Layer Configuration documentation for more information about the basic configuration rules.
〔Case 1〕If TensorSpace Model has loaded a pre-trained model before initialization, there is no need to configure network model related parameters.
TSP.layers.Dense();
〔Case 2〕If there is no pre-trained model before initialization, it is required to configure network model related parameters.
[Method 1] Use units
TSP.layers.Dense( { units: Int } );
[Method 2] Use shape
TSP.layers.Dense( { shape : [ Int ] } );

Arguments

Name

Tag

Type

Instruction

Usage Notes and Examples

units

Int Amount of nodes of FC layer,
Network Model Related
For example, units = 100
means there are 100 neural in the fully connect layer

shape

Int[] Output shape,
Network Model Related
For example, shape: [ 100 ]
means the output is 1-dimensional array by 100

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 the layer For example, name: "layerName"
In Sequential Model: Highly recommend to add a name attribute to make it easier to get Layer object from model.
In Functional Model: It is required to configure name attribute for TensorSpace Layer, and the name should be the same as the name of corresponding Layer in pre-trained model.

color

Color Format Color of layer Dense's default color is light green #00FF00

closeButton

Dict Close button appearance control dict. More about close button

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

ratio: Int. Times to close button's normal size, default is 1, for example, set ratio to be 2, close button will become twice the normal size

initStatus

String Layer initial status. Open or Close. More about Layer initial Status close[default]: Closed at beginning,
open: Open at beginning

animeTime

Int The speed of open and close animation For example, animeTime: 2000
means the animation time will last 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 of 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 customized name of 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.
Methods
filter_center_focusLink this layer to previous layer.
filter_center_focusThis method can be use to construct topology in Functional Model.
filter_center_focus See Construct Topology for more details.
.openLayer() : void
filter_center_focus Open Layer, if layer is already in "open" status, the layer will keep open.
filter_center_focus See Layer Status for more details.
filter_center_focus Close Layer, if layer is already in "close" status, the layer will keep close.
filter_center_focus See Layer Status for more details.
Examples
filter_center_focus If TensorSpace Model load a pre-trained model before initialization, there is no need to configure network model related parameters.
let denseLayer = new TSP.layers.Dense( {

    // Recommend Configuration. Required for TensorSpace Functional Model.
    name: "Dense1",
    // Optional Configuration.
    initStatus: "open"

} );
filter_center_focus If there is no pre-trained model before initialization, it is required to configure network model related parameters.
let denseLayer = new TSP.layers.Dense( {

    // Required network model related Configuration.
    units: 1000,
    // Recommend Configuration. Required for TensorSpace Functional Model.
    name: "Dense2",
    // Optional Configuration.
    initStatus: "open"

} );
