The application is not like an ordinary chat application, but aims to keep its place in the market with a clean user interface, a solid application structure over a user-friendly and secure network. The app will provide a modern approach to chat apps using new technologies for the community. It aims to use more machine learning approaches to determine a person's emotional state and then react to it, and try to create artificial emotional intelligence.

Before you begin, ensure you have met the following requirements:

• You have Android Studio installed in your machine
  
• You have a Android Device or Emulator with Android Version 6.0 or above.
  
• You should read SRS documentation.

Our applications enable users to communicate with each other and communicate securely by using new technologies. We will provide a great app for people to communicate with each other that they know using their contact lists whether they give permissions. The main functionality of the application gives the opportunity to the user. These are described below

• send and receive text messages
• sending images and files
• scheduling messages
• sending location
• sending voice recording
• voice and video calling with end-to-end encryption
  Another functionality is that it offers features such as taking photos, adding filters, and editing images. We will also be implementing machine learning applications. For the profile picture, the application will force to the user set the profile picture as a real picture of themselves. Some machine learning applications will be applied to our applications. Some of them described below:
  
• Emotion Recognition
  It is a subset of artificial intelligence that measures, understands, simulates, and reacts to human emotions. It’s known as artificial emotional intelligence. The AI will try to determine your emotional expression based on their dialogues in the chat application. In case you’re wondering, this is how some of those are 8 emotions: neutral, happy, sad, surprise, fear, disgust, anger, and contempt.
  Dataset : We will take a Twitter dataset which is provided by Kaggle for text classification competitions. It includes 40,000 tweets labeled respectively to 13 different human emotions. The result of the model will be presented in the user interface using color psychology according to the result of the model.
  Preprocessing : Stemming and lemmatization are two crucial steps of pre-processing. In stemming, we will convert words to their root form by truncating suffixes. This process reduces the unwanted computation of sentences. Lemmatization involves morphological analysis to remove inflectional endings from a token to turn it into the base word lemma.
  Model: We will use Bidirectional LSTM for model. Bidirectional long-short term memory (Bi-LSTM) is a Recurrent Neural Network architecture where makes use of information in both directions forward or backward.
  
  
• Age Estimation
  Dataset: We will train our model on the UTKFace dataset which contains 23K images.
  Preprocessing: We use 3-channeled RGB images as input. The age estimation model takes in 200 * 200 images as input.
  Model: We will use CNN for face recognition. A CNN is trained to detect and recognize face images. The model will build using Keras Convolution 2D layers.
  
• Gender Estimation
  
  Dataset: The dataset for gender estimation will be same as the dataset we will use for age estimation. Preprocessing*: We use 3-channeled RGB images as input. The age estimation model takes in 128 * 128 images as input.
  Model: The model will be the same as the age estimation with a small difference to adapt the binary classification.

The project is currently under development

• Generate anime faces using users profile pictures
  Using the DCGAN algorithm, we will build a model to generate an anime picture based on users' profile pictures. When the user updates their profile picture, the user will be able to create that picture and they will have a dialog bar to set the profile picture.
