LSTM Neural Network for Accelerometer Data Processing

Do you know why smartphones need embedded accelerometers? – At first, you may think it’s only for changing the screen's orientation. But the role of the accelerometer isn’t limited to just that. This small device allows you to collect data on different types of object movement. Exploiting the accelerometer data to model types of object movement requires some sophisticated algorithmic processing and machine learning techniques to cope with phone orientation changes, different type of phone accelerometer characteristics, and more. In this article, we describe how we coped with these challenges, and we present the results of training an LSTM neural network to process the accelerometer sensor data.

AI: Recommendation Systems for Retailers

Retailers have to compete with E-commerce shops to retain customers. Online commerce main advantages include receiving feedback quickly, opportunities to store and process data, and to answer the client requests in real time. Retail stores cannot get an immediate response from the customers, but the majority of retailers has a loyalty program and purchase information such as receipts. It's enough to create a recommendation system and provide a personalized approach to customers for increasing profits.

Information Retrieval from OCR Text

Information retrieval from OCR text

Information retrieval is an essential stage in the analysis of camera-captured text data as there are many areas where it can be used. For example, it is highly demanded in the receipt recognition services because the quality of the recognized texts needs to be improved. To improve the effectiveness of the information retrieval from OCR texts, our R&D engineers have used LSTM recurrent neural network.

Object Detection Using Fully Convolutional Neural Networks

Object detection Using Fully Convolutional Networks

Research on artificial neural network training is most widely used to automate multimedia data recognition. Among other things, it’s important that various types of neural networks show strong results in the tasks of speech and image recognition, financial forecasts, machine translation, and many others. We have effectively applied fully convolutional neural networks within the receipt recognition research.

Applying OCR Technology for Receipt Recognition

Applying OCR Technology for Receipt Recognition

When it comes to the receipt recognition, it often relates to the appearance of complications with OCR methods. Extracting information from receipts implies taking a raw, badly structured text with custom characters and displaying normalized data on a device screen. Convolutional neural networks (CNN) can facilitate this process. Using CNN, we work on the comprehensive solution that can be easily adjusted to process receipts from different countries.

Convolutional Neural Networks for Object Detection

Convolutional Neural Networks for Object Detection

Deep learning is an extremely popular field these days. Convolutional Neural Networks have successfully proven themself in computer vision. As a result, we decided to test in practice the effectiveness of convolutional neural nets for object detection in images. As the object of our research, we chose license plate and road sign pictures.

Classification of EEG Signals for Brain-Computer Interface

Using brain-computer interface could facilitate everyday life of paralyzed or disabled patients. With a spate of interest in this topic, Azoft R&D department, together with Sergey Alyamkin and Expasoft participated in "Grasp-and-Lift EEG Detection" competition organized by Kaggle. The competition was dedicated to classifying various movements of the right hand via EEG (electroencephalogram) for a brain-computer interface development.

Machine Learning Methods in Video Annotation

Machine Learning Methods in Video Annotation

Research and development in the field of image and video processing is an important and popular task today. In the era of mobile technologies almost anyone can make a video and upload it on youtube or any other hosting service. To find relevant videos, they need to be classified. One way to handle video classification is by using tags annotation.
