It reads 2,114 bp of one-hot encoded sequence and outputs both a base-resolution profile over the central 1,000 bp, covering both strands as a single softmax so the model can learn strand asymmetry, and a scalar giving the log total number of initiation events in that window. Training used ENCODE PRO-cap read alignments in which the first read of each pair was discarded and only the single 5'-most base of the second read was kept, merged across replicates and kept separate by strand. Each model was trained on all PRO-cap peaks in its cell line plus randomly sampled DNase-hypersensitive sites from the same cell line at a 7:1 peak to background ratio, with 7-fold cross-validation split by chromosome. Bases that are not uniquely mappable by 36-mer reads were given zero loss weight during training. -Full details are in Cochran <em>et al</em>. +Full details are in Cochran <em>et al.</em>, 2024. </p> <h3>Predicted PRO-cap</h3> <p> Genome-wide predictions were generated by the Kundaje lab by applying the model to every 2,114 bp window at a stride of 250 bp, so each base is the average of four overlapping predictions, then averaging across the seven cross-validation models and across the forward and reverse-complemented sequence. On hg38 no prediction was made where most of a window was unresolved (N) in the reference. </p> <h3>Sequence contribution scores</h3> <p> Scores were computed with DeepSHAP, which estimates each base's contribution by contrasting the model's output on the real sequence against its output on a set of reference sequences, here 25 dinucleotide shuffles of the sequence being scored. Because DeepSHAP needs a single scalar to explain, the base-resolution profile output was summarized by mean-normalizing the pre-softmax logits and taking their dot product with the post-softmax profile, which weights each base's logit by its predicted probability of being used and sums over the 1,000 bp output window and both strands. This is the profile or TSS-positioning task; ProCapNet can also produce scores for its read-count task, which are not -shown here. Each scored sequence was run through all seven cross-validation +included in this track. Each scored sequence was run through all seven cross-validation models and in both orientations, and the scores averaged. </p> <h3>Source</h3> <p> The ProCapNet model implementation is at <a href="https://github.com/kundajelab/ProCapNet" target="_blank">kundajelab/ProCapNet</a>.
