Mar 6, 2002

Appl. No.:

10/030371

Inventors:

Sigurd Wagner - Princeton NJ
Yu Chen - Milpitas CA

Assignee:

The Trustees of Princeton University - Princeton NJ

International Classification:

H01L 2100

US Classification:

438154, 438151, 438153, 157 64, 157347

Abstract:

A p channel thin-film transistor (TFT) made of directly deposited microcrystalline silicon (uc-Si). The p TFT is integrated with its n channel counterpart on a single uc-Si film, to form a complementary metal-silicon oxide-silicon (CMOS) inverter of deposited uc-Si. The uc-Si channel material can be grown at lower temperatures by plasma-enhanced chemical vapor deposition in a process similar to the deposition. The p and n channels share the same uc-Si layer. The Figure shows the processing steps of manufacturing the TFT, where ( ) represents the uc-Si layer of the device.

US Classification:

438/154000

Abstract:

A p channel thin-film transistor (TFT) made of directly deposited microcrystalline silicon (c-Si). The p TFT is integrated with its n channel counterpart on a single c-Si film, to form a complementary metal-silicon oxide-silicon (CMOS) inverter of deposited c-Si. The c-Si channel material can be grown at lower temperatures by plasma-enhanced chemical vapor deposition in a process similar to the deposition of hydrogenated amorphous silicon. The p and n channels share the same c-Si layer.

H04W 24/08

Abstract:

A processing system including at least one processor may obtain operational data from a radio access network (RAN), format the operational data into state information and reward information for a reinforcement learning agent (RLA), processing the state information and the reward information via the RLA, where the RLA comprises a plurality of sub-agents, each comprising a respective neural network, each of the neural networks encoding a respective policy for selecting at least one setting of at least one parameter of the RAN to increase a respective predicted reward in accordance with the state information, and where each neural network is updated in accordance with the reward information. The processing system may further determine settings for parameters of the RAN via the RLA, where the RLA determines the settings in accordance with selections for the settings via the plurality of sub-agents, and apply the plurality of settings to the RAN.

International Classification:

G06F 17/30

Abstract:

The ranking quality of a ranked list may be evaluated. In an example embodiment, a method is implemented by a system to access log data, ascertain which entries of a ranked list are skipped, and determine a ranking quality metric from the skipped entries. More specifically, log data that reflects user interactions with a ranked list having multiple entries is accessed. The user interactions include at least indications of which of the multiple entries are selected entries. It is ascertained which entries of the multiple entries of the ranked list are skipped entries based on the selected entries. The ranking quality metric for the ranked list is determined responsive to the skipped entries.
