Martin Lewis' MSE shares simple way to get free £200 cash

Martin Lewis' MSE shares simple way to get free £200 cash Here's who is eligible and what you'll need to do if you are Brits hoping to bolster their bank balance could receive a free £200, as highlighted by Martin Lewis' Money Saving Expert. The MSE team is making people aware that First Direct is offering a cash incentive to attract new customers. Banks regularly launch switching deals as a way to grow their customer base.

Expectations vs. Realities: The Cost of MSE-Optimal Forecasting Under Conditional Uncertainty

Announce Type: new Abstract: Multi-step time series forecasting (MSF) is commonly evaluated using point-wise error metrics such as mean squared error (MSE), implicitly treating the conditional mean as a sufficient target. We show that this can be misleading under conditional uncertainty, where the conditional expectation becomes unrepresentative of typical realized values at longer horizons. We formalize this effect through a conditional uncertainty gap and prove that whenever this gap is...

Beyond MSE: Improving Precipitation Nowcasting with Multi-Quantile Regression

arXiv:2605.30122v2 Announce Type: replace Abstract: Deep-learning precipitation nowcasting models are often optimized using pointwise losses such as mean squared error or mean absolute error, which can lead to overly smooth forecasts and poor representation of heavy rainfall. This study investigates whether the predictive performance of an established deterministic nowcasting architecture can be improved by reformulating training as a multi-quantile regression problem. Using SmaAt-UNet as a...

Almost 900,000 NHS prescription patients 'missing out' on huge savings

Almost 900,000 NHS prescription patients 'missing out' on huge savings Personal finance expert Martin Lewis has said 'We need to spread the word to anyone in England' Anyone who regularly collects prescriptions is being advised they could make considerable savings by signing up to an NHS scheme. Martin Lewis' MSE website has highlighted that nearly 900,000 patients could be missing out, according to recent analysis. The NHS prescription prepayment scheme was set up as a means of helping...

Score Broadcast and Decorrelation: A General Framework for Broadcast-Based Credit Assignment

arXiv:2605.30638v1 Announce Type: new Abstract: We introduce Score Broadcast and Decorrelation (SBD), a principled framework for broadcast-based credit assignment for general families of differentiable losses. Error broadcast is a biologically plausible alternative to backpropagation that sends output information to hidden layers without weight transport. The Error Broadcast and Decorrelation (EBD) framework, recently introduced for the mean-squared-error (MSE) setting, grounded this...

Deliberate Evolution: Agentic Reasoning for Sample-Efficient Symbolic Regression with LLMs

Announce Type: new Abstract: Symbolic regression (SR) discovers compact mathematical expressions from data, yet recent LLM-based evolutionary methods remain sample-inefficient because they rely mainly on scalar feedback such as MSE. We identify a core limitation: existing methods conflate candidate proposal with search guidance, requiring the LLM to infer how to evolve an expression, diagnose its errors, and reuse past experience from a single score. To address this, we propose Deliberate...

Cosine Misleads: Auxiliary Losses Reshape Vision Language Models, Not Their Latents

arXiv:2606.05753v1 Announce Type: new Abstract: Latent visual reasoning (LVR) inserts supervised latent tokens between perception and answer generation in vision-language models (VLMs). The field uses alignment between these latents and their visual targets, i.e., cosine similarity or mean squared error (MSE), as both the training loss and the quality metric, assuming that better alignment yields a better answer. We test this with a designed matrix of five LVR variants and find the...

Workers given 5 per cent pension warning as you could be losing out

Workers given 5 per cent pension warning as you could be losing out Money Saving Expert has warned people not to opt out of their workplace pension or drop contributions below five per cent Workers have been issued a five per cent pension warning, as they risk "throwing away free cash". You could be missing out on vital funds without even realising it. In the UK, most people have access to two types of pension: the State Pension and a workplace pension.
