-I made some toy examples which is similar with Apple's Sticker.
-The Mobile ssd V2 tensor flow lite model is used for the feature extractor and Nearest Neighbor is used for the classifier. All the training and testing is done on the Galaxy S8.

+NNtrainer is a Software Framework for training Neural Network models on devices.
-Happy(^^), sad(TT), soso(ㅡㅡ) classes are used and prepare 5 images for the training and two images for the test set each as below.
+## Overview
-
+NNtrainer is an Open Source Project. The aim of the NNtrainer is to develop a Software Framework to train neural network models on embedded devices which have relatively limited resources. Rather than training whole layers of a network from the scratch, NNtrainer finetunes the neural network model on device with user data for the personalization.
-After remove the fully connected layer of mobile ssd v2, 128 features are extracted. The features from first training set data is below.
+Even if NNtariner runs on device, it provides full functionalities to train models and also utilizes limited device resources efficiently. NNTrainer is able to train various machine learning algorithms such as k-Nearest Neighbor (k-NN), Neural Networks, Logistic Regression, Reinforcement Learning algorithms, Recurrent network and more. We also provide examples for various tasks such as Few-shot learning, ResNet, VGG, Product Rating and more will be added. All of these were tested on Samsung Galaxy smart phone with Android and PC (Ubuntu 18.04/20.04).

+- Ready: CI system ensures build-ability and unit-testing. Users may easily build and execute. However, we do not have automated release & deployment system for this instance.
+- Available: binary packages are released and deployed automatically and periodically along with CI tests.
+- [Daily Release](http://ci.nnstreamer.ai/nntrainer/ci/daily-build/build_result/)
+- SDK Support: Tizen Studio (6.0 M2+)
-Due to the simplicity of this toy example, all the test results are collect.

-I made two more random pictures which little bit differ from right image. As you can see, it is little bit hard to tell which class it is. First image could be classified as "happy" but the red zone is across with sad and the variance is quite small. Second image is more confused. Cause the smallest distance is all over the classes.
-May be should be define the threshold which I didn't.^^;;

+### Tensor
+
+Tensor is responsible for calculation of a layer. It executes several operations such as addition, division, multiplication, dot production, data averaging and so on. In order to accelerate calculation speed, CBLAS (C-Basic Linear Algebra: CPU) and CUBLAS (CUDA: Basic Linear Algebra) for PC (Especially NVIDIA GPU) are implemented for some of the operations. Later, these calculations will be optimized.
+Currently, we supports lazy calculation mode to reduce complexity for copying tensors during calculations.
