U.S. Aims to Penalize Disabled Adults Who Live with Their Families
6 hours ago
- Shy'tyra Burton has severe disabilities and receives Supplemental Security Income (SSI) to live with her low-income father.
- The Trump administration is proposing a rule to deduct the value of a disabled adult's bedroom from SSI benefits if they live with family, potentially cutting benefits by up to a third.
- This change could affect up to 400,000 poor, disabled, or elderly individuals across the U.S., particularly those in families also receiving SNAP benefits.
- Opponents argue the rule is inhumane and may increase costs if individuals move to institutional care instead of staying at home.
- The SSI program is complex and administratively costly, with strict eligibility and ongoing reviews, which this rule could exacerbate.
- The Biden administration had simplified SSI rules for families already qualifying for other aid, but the Trump rule would reverse this, requiring detailed monthly reporting.
- Social Security Commissioner Frank Bisignano faces internal tension over the rule's efficiency claims versus increased burdens on families and agency staff.

Softmax, can you derive the Jacobian? And should you care?
4 days ago
- Softmax transforms a vector of real numbers into a probability distribution by exponentiating each input and normalizing by the sum of all exponentials, mapping inputs onto a probability simplex.
- The function exhibits 'winner-takes-most' behavior: it amplifies the largest logit and suppresses smaller ones, making predictions more decisive but potentially overconfident for uncertainty estimation.
- Softmax is numerically unstable due to exponential overflow; a common fix is subtracting the maximum input value (max normalization) to prevent overflow without changing the output.
- The Jacobian of softmax reveals coupling between dimensions: increasing one input increases its own output and decreases others due to the sum-to-one constraint, with a structure of a diagonal matrix plus a rank-1 correction.
- Backward propagation through softmax can be computed efficiently without materializing the full Jacobian using elementwise operations and a dot product, reducing memory usage (critical for large vocabularies like in language models).
- Softmax is often used with cross-entropy loss, yielding a simplified gradient expression: the difference between predicted probabilities and true labels; in practice, these operations are fused for efficiency.
- In practice, softmax operates on batches and sequences with an axis parameter to specify normalization direction (e.g., over classes or sequence positions), and a temperature parameter can control distribution sharpness.
- High temperatures flatten the softmax output towards uniformity, while low temperatures sharpen it towards a one-hot encoding, allowing control over model creativity versus determinism, especially in language models.

- High temperatures flatten the softmax output towards uniformity, while low temperatures sharpen it towards a one-hot encoding, allowing control over model creativity versus determinism, especially in language models.
Apple Says Mac Studio and Mac Mini Will Be in Short Supply for Months
4 hours ago
- Apple CEO Tim Cook announced that the Mac mini and Mac Studio may face supply shortages for several months due to higher than anticipated demand.
- Demand for these devices is driven by their suitability for AI and agentic tools, which customers recognized faster than Apple predicted.
- Shipping delays have increased, with some configurations showing delivery estimates of 4-5 months or being listed as 'Currently Unavailable' due to a global memory chip shortage affecting RAM availability.
- Apple has stopped selling some models, like the Mac Studio with 512GB RAM, and halted orders for others with higher RAM upgrades.
