Weight Feedback Computes the Jacobian Transpose Locally in Modern Deep Networks

A fully-local predictive-coding learning rule that removes backpropagation's Jacobian transpose from error transport — and, unlike previous predictive-coding methods, gets better as the network gets deeper.

From Dataset to Real-world: General 3D Object Detection via Generalized Cross-domain Few-shot Learning

A unified framework for 3D detection that survives the move out of the dataset — combining multi-modal fusion with contrastive-enhanced prototype learning to face domain shift and data scarcity at once.

Heating season
Lanterns still up, no traffic
The last of the light
Rapeseed, and the village behind it
Swept leaves, poplar wood
The building, from below
The lights still on
Through the window, past the car
Turbine, from a moving window
Two, on the snow
Waiting on the far side
Wires, and the stars behind them
A red-and-white striped chimney behind a red brick plant building, its plume flattening into a long grey band across a pale winter sky.
Heating season
An empty multi-lane avenue at night, bare trees on both sides, ornate street lamps flaring into starbursts and red lanterns hung along the median.
Lanterns still up, no traffic
Winter sunset behind a campus: an orange sky crossed by a single contrail, a lattice tower on the skyline, and empty snow-covered stands beside a football pitch.
The last of the light
A flat field of yellow rapeseed in flower under a wide blue sky, with a low line of village houses along the far horizon.
Rapeseed, and the village behind it
Bare poplars in dry sandy ground, with fallen leaves raked into low mounds and a broom left lying among them.
Swept leaves, poplar wood
A narrow concrete apartment tower photographed from its base at dusk, its stained façade tapering to a point against a flat violet sky.
The building, from below
A dark building at night with three bands of lit windows; a small figure in red walks the path below, alone.
The lights still on
Seen over the roof of a parked car at night: two people sit facing each other at a small table inside a lit bakery, one reaching across.
Through the window, past the car
A white wind turbine standing above a blurred hillside of scrub and bare trees, the foreground smeared by motion.
Turbine, from a moving window
Two pigeons foraging on thin snow scattered with pine needles — one slate grey, one pale brown, facing away from each other.
Two, on the snow
A wide winter crossing painted with chevrons and stripes; a single figure in a dark coat stands alone at the far kerb beneath an overpass column.
Waiting on the far side
A dense hedge lit from below at the foot of the frame, with power lines crossing a black sky full of faint stars above it.
Wires, and the stars behind them

Writing

我转身背离过去，面对火焰，把遗憾烧尽。

I turned from the past to face the flame, and burned the regret away.

人们用道路切割大地；高楼大厦就是人类的蜂巢。

People cut the earth apart with roads; the towers are the human hive.
