very nice paper - clean and convincing. The authors successfully predict translation initiation sites (TIS) based on canonical (AUG) and non-canonical (CUG, GUG, UUG, etc.) start sequences and +/- 100 bp surrounding sequence context. They compare TIDE to alternative TIS prediction algorithms and show that their method outperforms others by a wide margin. Additionally, their code is made public (https://github.com/zhangsaithu/tide_demo), which is awesome! Thanks @zhangsaithu - we'd love to get your feedback on this paper as well.
I am thinking that I will use this paper in the "study gene expression" section. There appear to be (more recent) efforts to apply deep learning to study gene regulation, which I think fits nicely in that section. (Also see #74.)
Predicts TIS in HEK cells using a QTIseq dataset. Briefly, QTIseq profiles translation initiating ribosomes genome-wide. The authors identify interesting alternative site preferences and observe how local sequence context can impact translation efficiency. They confirm their results based on their identification of Kozak sequences as important indicators of translation efficiency.
One hot encoded {A,C,U,G}
amino acid sequences of length 203 (+/- 100 aa + 3 start codons) fed into CNN with max pooling and dropout followed by an LSTM RNN with a logistic output layer that determines the probability of the sequence being a TIS. They deal with unbalanced classes using a bootstrap sampling method and report performance using ROC and PR curves.
Training and architecture implemented in Keras.
Here is another paper with a similar architecture: http://ieeexplore.ieee.org/document/7822515/
The similar paper mentioned above, DeeperBind, is #149
I see,
Thanks.
