06 Mar 2025 | Data Structures in Bioinformatics

Jens and Johanna visited the workshop Data Structures in Bioinformatics in Pisa and presented their work on probabilistic filters.
Jens gave a talk about Blocked Bloom filters with Choices. This approach improved the FPR of Blocked Bloom filters by a more balanced load per block.
Johanna gave a talk about Better Cuckoo filters, introducing a windowed memory layout to increase the fill rate of Cuckoo filters.

02 Oct 2024 | GCB 2024

We had wonderful days at GCB 2024 in Bielefeld. The group was very active:

• We organized a workshop on Just-in-time compiled Python for bioinformatics research.
• Sven co-organized the workshop on Bioinformatics Education, attempting to harmonize BSc curricula in Germany.
• Johanna presented a poster on the unseen species estimation problem.
• Jens gave a highly praised talk on efficiently computing strong vs. weak k-mers in large k-mer sets. We can mark weak k-mers in the human reference genome in 40 seconds.
• We also announced that we will host GCB in Saarbrücken in 2026.
