Time Series Prediction


Time Series Prediction sample application

This demonstration tries to solve yet another task with Genetic Programming and Gene Expression Programming. For the given time series it tries to build an algebraic expression, which calculates next time series value from the given known past values. Once a good expression is found during training phase, the expression may be tried to predict future data points from the last known values.

 

Hands Gesture Recognition

This sample demonstration uses motion detection as its first step and then does some interesting routines with the detected object - hands gesture recognition. Let's suppose we have a camera, which monitors some area. When somebody gets into the area and makes some hands gestures in front of the camera, application should detect type of the gesture and raise an event, for example. When the hands gesture recognition is detected, the application may perform different actions depending on the type of gesture. For example, gestures recognition application may control some sort of device or another application sending different commands to it depending on the recognized gesture. What type of hands gestures are we talking about? This particular application recognize up to 15 gestures, which are combination of 4 different positions of 2 hands - hand is not raised, raised diagonally down, diagonally up or raised straight.

Speech Recognition & Text to Speech

If you are interested in computer text to speech (TTS) and speech recognition (SR), this demonstration is for you, it will demonstrates the speech technologies for more than 26 different languages :

Multiple face detection and recognition in real time

The facial recognition has been a problem very worked around the world for many persons; this problem has emerged in multiple fields and sciences, especially in computer science, others fields that are very interested In this technology are: Mechatronic, Robotic, criminalistics, etc. In this demonstration  the main goal is showing a face detector and recognizer in real time for multiple persons using Principal Component Analysis (PCA) with eigenface for implement it in multiple fields.

 

An example of EigenFaces:

Traffic Sign Detection

Traffic sign detection is a crucial component in an autonomous vehicle navigation system. For an automobile to navigate itself safely in an urban environment, it must be able to understand traffic signs

  • It should be able to read the speed limit, such that it will not received tickets for speeding and paid a premium on its insurance
  • It should be able to read traffic lights and stop on red
  • It should be able to read stop sign and yield to other vehicles which are also crossing the same intersection.
  • ...

This demonstration aims to solve a small part of a autonomous vehicle navigation system, which detect stop sign from images captured by camera.

Natural Language Processing Tools

This application is a collection of natural language processing tools.

Currently it Demonstrates the following NLP tools:

  • a sentence splitter
  • a tokenizer
  • a part-of-speech tagger
  • a chunker (used to "find non-recursive syntactic annotations such as noun phrase chunks")
  • a parser
  • a name finder
  • a coreference tool
  • an interface to the WordNet lexical database

 

Parser demo user interface

This application shows the generation of parse trees for English language sentences, as well as explores some of the other features of the Natural Language Processing.

Detect a written text's language

The language detection of a written text is probably one of the most basic tasks in natural language processing (NLP). For any language depending processing of an unknown text, the first thing to know is which language the text is written in.
