Building Your First Machine Learning Model
Creating a machine learning model using TensorFlow.js begins by understanding its basic structure. A typical model consists of layers that process data, with each layer performing a distinct transformation on the input data. This structure allows the model to learn and predict outcomes effectively.
Detailed Walkthrough
To build a simple model, start by importing TensorFlow.js into your project. Use the tf.sequential()
function to set up a model container, which is essentially a stack of layers. Each layer needs to be defined with its specific attributes and activation functions. An example of a dense layer would be:
const model = tf.sequential();
model.add(tf.layers.dense({units: 10, activation: 'relu', inputShape: [5]}));
Explanation of Relevant Code Snippets
In the snippet above, tf.layers.dense
creates a fully connected layer with 10 units and a ‘relu’ activation function. The inputShape
property denotes the shape of the input feature vector. After defining layers, compile the model with optimisers and loss functions to measure its learning efficacy. The final step involves training the model using model.fit()
, supplying training data and specifying epochs
for iteration cycles.
