Posts about the Microsoft CNTK deep learning code library

Processing the Contents of a CNTK Mini-Batch

CNTK v2 is a relatively new (mid-2017) deep learning code library. One of the advantages of using CNTK, rather than coding from scratch, is that CNTK has data reader functions. If you can fit all your data into memory, then … Continue reading

Time Series Regression using CNTK LSTM

Over the past few weeks I’ve been spending some time looking at LSTM networks using CNTK. LSTM (long short-term memory) networks are useful when predicting sequences, such as the next word in a sentence when you know the first few … Continue reading

I Track Down a Nasty Bug in a CNTK Classification Program

I’m a big fan of the CNTK library. But . . . CNTK is a powerful library of machine learning code. Whenever I look at a machine learning library (such as TensorFlow, Keras, Caffe, Theano, scikit-learn, Torch) my first example … Continue reading

Time Series Regression with Keras over CNTK with Multi-Data Input Sequences

Time series regression is a very challenging class of problem. A classic benchmark dataset is the international airline passenger data. It covers 144 months, from January 1949 (when there were 112,000 passengers) through December 1960 (when there were 432,000 passengers). … Continue reading

Time Series Regression using Keras over CNTK with a LSTM Network

Suppose you have some historical data that shows the total number of airline passengers, every month, for a few years. The goal of time series regression is to predict the number of passengers in the next month. Time series regression … Continue reading

Using Keras with CNTK on MNIST

There’s a lot of acronyms in the title of this blog post. Microsoft CNTK is a code library that can do deep neural networks. CNTK is written using C++ but you use CNTK by calling it from a Python program. … Continue reading
