Fashion Lookup

06 - 2018

Techinical: Doc2Vec, Edit Distance, Float Vector Indexing and Search.

Fashion Lookup is a system which helps users find their desired clothing item with a single query image. Our system employs state-of-the-art Deep Learning techniques in clothes recognition and image similarity learning. Aslo, we build a new indexing method named Quantization Indexing which transforms a vector in numerical space into text space, therefore, the searching for similar clothing items can be done with the help of Elasticsearch. Moreover, the clothes recognition network is converted into mobile-ready version and runs directly on users' mobile device. All the mentioned features help our sytem achieve an impressively low latency, even when the query database is large.

Face Recognition

Techinical: Tensorflow, face net, yolo.

In this project, we use IP camera to cellect multiple photos of staffs member at Framgia Inc. The dataset is, then, used to train a deep convolutional neural network which can verify whether a person is an employee of Framgia Inc or not. With the help of the system, we can enhance the security at the working space.

HR Auto Scoring

01 - 2019

Techinical: Tensorflow, OpenCV, SVM.

This is the service which is made in order to help HR department to save time and effort when dealing daily with large amounts of results from multiple-choice tests of candidates applying to the company. The service uses image processing methods combined with deep learning to accurately locate the answer areas, thereby determining the answers that the candidate chooses, then comparing the users answers with predefined answers in the system to return the results. The results are accurate at negligible speeds.

Techinical Article Spam Detection

06 - 2018 https://machine-learning.viblo.asia/

Techinical: NLP Feature Extraction, Word Embedding, Random Forest, Gradient Boosting.

Identify whether a post is spam or not. We train the spam detector with about 15000 labeled posts from Viblo, news, and advertisements as well. The accuracy of our spam detector is reported to be extremely high (99.7%) and the processing time is impressively low (ms).

Article Tag Compare

06 - 2018 https://machine-learning.viblo.asia/

Techinical: Word Embedding, Float Vector Indexing, Float Vector Retrieval.

Find tags which have the same meaning. Our service can automatically find tags which have the same meanings. The training data are technical posts from Viblo platforms and their corresponding tags.

Techinical Article Auto Tagging

06 - 2018 https://machine-learning.viblo.asia/

Techinical: NLP Feature Extraction, Word Embedding, TF-IDF.

Automatically find relevant tags for a post. We train the auto-tagging model with a large number of posts from Viblo which contain a lot of technical keywords. After the training phase is done, we can use it to find relevant tags for a given post.

Article Language Detection

06 - 2018

Article Language Detection

06 - 2018 https://machine-learning.viblo.asia/

Techinical: NLP Feature Extraction, Word Embedding, LSTM.

Detect the language of a post. We employ the Graph-based N-Gram technique and other methods for handling Unicode characters to detect language written in a post. With the detected language, we can help Viblo users to find suitable posts to their need. Besides that, our language detector can effectively aid Elasticsearch engine to achieve more accurate results.

Article Recommendation System

06 - 2018 https://machine-learning.viblo.asia/

Techinical: Colaborative Filtering, Content based Recommendation, Doc2Vec.

Automatically recommend relevant posts on Viblo for users. Up to now, there are many technical posts on Viblo (over 20K posts of about 100 different subjects), and the number of posts tends to increase very rapidly. As such, users often encounter the problem of information overload; users usually find it difficult to find suitable posts to their need. Therefore, a recommendation system has been built in order to suggest relevant technical posts on Viblo for users based on their interest.

Article Plagiarism Detection

2018/10 https://machine-learning.viblo.asia/

Techinical: Doc2Vec, Edit Distance, Float Vector Indexing and Search.

Detect plagiarism in user's post. With a huge numbers of published technical posts, we has to cope with the problem of plagiarism. We don't want the content of a published post is a copy-paste work. Because of that, we aim to build a system which is capable of detecting plagiarism automatically. After that, the integrity of a post can be easily verified.

Cipher Cascade

2019 https://ciphercascade.com

Techinical: Ethereum, Loom Network, Web3js, Reactjs.

Cipher Cascade is a game developed with Blockchain technology, and can be played easily on PC and Smartphone browsers. Normally, the processing speed of transactions on Ethereum platform is quite slow, when it takes more than ten seconds to create a block. Cipher Cascade is building a side chain, which is connected to the Ethereum main chain to speed up transaction processing, allowing users to play the game at a smoother speed. In addition, by storing tokens and game logic on the side chain, users can play games, as well as trade, manage token assets without having to pay any "gas" for the transaction.
