Beyond Sinusoids: A Morlet Wavelet Framework for Transformer Positional Encoding
arXiv:2606.01258v1 Announce Type: new Abstract: Standard positional encodings for transformers - sinusoidal and rotary (RoPE) - treat every position as equally local: they encode where a token is, but not how far its positional influence should extend. We propose that the Morlet wavelet, which simultaneously minimises uncertainty in position and frequency, is the natural basis for positional encoding, and introduce Morlet Positional Encoding (MoPE): each embedding dimension learns its own...
Polynomial-time satisfiability for a special case of Positive$\wedge$Negative
Announce Type: new Abstract: A Boolean function in CNF format is of type Positive$\wedge$Negative} if each clause C is either positive (i.e. all literals of C are positive) or negative (i.e. all literals of C are negative). As is well known, deciding the satisfiability of such CNFs is NP-complete. We say that a CNF is of type DisjointPositive if its clauses are positive and mutually disjoint.
Zelensky says he had 'positive' talks with Trump envoys on Ukraine war
Zelensky says he had 'positive' talks with Trump envoys on Ukraine war Ukrainian President Volodymyr Zelensky said he held a positive conversation with US envoys Steve Witkoff and Jared Kushner on Monday, signalling renewed efforts to advance diplomacy over the war with Russia. The call came as European leaders backed a proposed meeting between Zelensky and Vladimir Putin to seek a ceasefire. Ukrainian President Volodymyr Zelensky said on Monday he had a "positive" conversation with US...
GridPE: A Grid Cell-Inspired Unified Position Embedding for Arbitrary-Dimensional Spaces
arXiv:2406.07049v3 Announce Type: replace Abstract: Understanding spatial relationships across all dimensions is fundamental for intelligent systems. However, existing positional embeddings, such as Rotary Positional Embedding (RoPE), lack theoretical guarantees for high-dimensional spatiotemporal tasks like video understanding and robotic navigation. Inspired by the hexagonal periodic coding of grid cells in mammalian spatial cognition, we propose GridPE -- a novel positional embedding...
Extremum Seeking Control Based Adaptive Compensation of Position Sensor Harmonics in PMSM Drives
arXiv:2606.07906v1 Announce Type: new Abstract: Permanent Magnet Synchronous Machines (PMSMs) have become one of the preferred forms of electromechanical energy converters, attributing to their high efficiency, torque density, and other unique advantages. However, given the need for proper rotor position measurement for commutation and field orientation, accurate rotor position sensing is of paramount importance. In sensing motor rotor position with a sensor, harmonic errors that arise in...

How NFL draft position overpromises player potential
How NFL draft position overpromises player potential Gaby Clark Scientific Editor Andrew Zinin Lead Editor A new analysis suggests there is no correlation between athlete performance and the way the NFL values draft positions, challenging long-held beliefs about how professional football teams select new players each year. Researchers found that higher-drafted players did not perform significantly better than lower-drafted ones, especially those chosen during the same round. These findings...
