Presenter : Juno

This seminar introduces several popular technologies in deep learning or neural network for natural language processing such as distributed representation of word, neural network language model, recurrent neural network, and LSTM (Long short term memory). In particular, recent advances and a couple of application examples will also be discussed in the last part.

Presenter : Juno

This seminar introduces Deep learning, which has been a buzz word in machine learning area for recent years. Since it is based on neural network, the seminar first introduces the basic theory and history of Neural network and explains why Neural network failed in 1990s and early 2000s. Unsupervised way of feature learning, is then followed to describe the core of Deep learning. The latter half of the seminar focuses on the algorithms that learn features from data in an unsupervised way. As a result, main algorithms such as Hopfield Net, Boltzmann machine, and Restricted Boltzmann machine will be discussed.

 

Brief Introduction to H/W Design

Presenter : Neil

I first introduced the most essential circuit elements for developing the hardware device and then explained how this element works.

Then I explained the two ways in which the signal runs through the circuit, how the aforementioned elements control the two signals, and how it applies practically.

And finally, with the introduction of the theories and additional information for the planning and development of the hardware, I have explained how to develop applications for the Wand product which I have created.

I have introduced all of the development sources and programs to our colleagues.

However, I have been deleted from our company blog to prevent improper use.

 

A Basic Tutorial to Logistic Regression

For more info  : log

presenter : Jay

The seminar covered the basics of logistic regression, which is the simplest method for classification. After going through an numeric example and the principle of maximum likelihood, an overview of logistic regression was given in relationship with other algorithms.The following was shown:
1. The equivalence between the Maximum Entropy algorithm and logistic regression
2. The equivalence between Naive bayes and logistic regression
3. How Conditional Random Fields are basically logistic regression with selective mapping of feature functions
Conclusively, it was shown that logistic regression is a simple algorithm which works well when classifying linearly separable data with a reasonable running time.
