A Beginner's Guide to Deep Learning

## Steps for building a deep learning model
The Keras workflow has the following steps to develop a deep learning model:




### 1. Read and explore the data
  This step requires reading and exploring the given dataset, preprocessing it (if required), and splitting the input features and the output label from the given dataset. These input features define _the number of nodes in the input layer_ of the Keras model. 
  

### 2. Specify architecture
  This step specifies the model architecture. For example:
   - _The number of layers_
   - _Nodes per layer_
   - _Activation function in each layer_

### 3. Compile the model
 The model compilation step involves:
   - _Specifying the loss function_
   - *Defining the optimization parameters*

### 4. Fit the model
 The model fitting helps train the model on the dataset. In short, it will begin the _optimization of model weights using backpropagation_.

### 5. Evaluate the model
The model evaluation step helps evaluate the model on the given dataset. The dataset can be a training set or a test set. This step _evaluates the model performance_.

### 6. Make predictions
The model trained on the training dataset can be used to make predictions on the unseen data. In short, given a testing dataset, we can _use the trained model to make predictions_.
