LSTM_protein

jLSTM_protein (new)

This is the recommended new JAVA-package of "Long Short-Term Memory" for Protein classification (jLSTM_protein). The implementation of the LSTM neural network is the same as in the C package and performs and behaves identically but faster. jLSTM_protein is multithreaded and therefore uses effectively multicore and -processor machines. Using more than one thread results in faster computation as in the C package. jLSTM_protein uses Biojava 1.6 for reading FASTA sequences. The Biojava package is included and needs no separate installation.

Download, tryout the software implementation with examples (Biojava 1.6 included) jLSTM_protein.tar.bz2

For Remote Homology detection experiments adding positive training sequences with PSI-BLAST searches gives best results. To do this we offer a complete environment based on Perl and NCBI PSI-BLAST. Here is the README.
For the SCOP 1.53 benchmark here are the datasets. The positive training sequences are already extended. datasetsSCOP1.53.tar.gz (gzip 39,7 MB) or datasetsSCOP1.53.tar.bz2 (bzip2 30,8 MB)
