    Neuralign puts neural recordings from different sessions into one tensor decomposition, sharing a time course while estimating trial and neuron weights per session

    Neuralign places neural recordings from different sessions and animals, with different sampled neurons, into one tensor decomposition in which each component shares a single temporal curve while trial strength and neuron weights are estimated per session, so no matched neurons or matched trials are needed. On 93 brain-wide recordings from 19 mice, an unsupervised fit yielded a single component that separated the three anterior lateral motor cortex (ALM) optogenetic inhibition conditions, with balanced accuracy of 0.647 on held-out sessions against a chance level of 1/3. That component's change showed a modest association with the drop in behavioural accuracy (ρ = 0.266 over 180 session–inhibition observations).

  2. IBM ships a four-model time-series ensemble that skips weight fitting, edging the best single model on GIFT-Eval

    IBM Research released Granite Timeseries Ensemble, a default forecasting recipe that combines four open Granite time-series models with different architectures and returns median and quantile forecasts without retraining or fitting ensemble weights. Previously a user had to judge which single model suited a given series. Across 97 GIFT-Eval configurations the probabilistic ensemble reaches a MASE of 0.683 against 0.685 for the strongest member, PatchTST-FM-r2, a small margin whose main benefit is not having to pick a model in advance.
