A unified view of TD algorithms, introducing Full-gradient TD and Equi-gradient descent TD

This paper addresses the issue of policy evaluation in Markov Decision Processes, using linear function approximation. It provides a unified view of algorithms such as TD(λ), LSTD(λ), iLSTD, residual-gradient TD. It is asserted that they all consist in minimizing a gradient function and differ by the form of this function and their means of minimizing it. Two new schemes are introduced in that ...

PES/Quaternized-PES Blend Anion Exchange Membranes: Investigation of Polymer Compatibility and Properties of the Blend

Polyethersulfone (PES)-based anion exchange blend membranes were prepared from quaternized-PES (Q-PES) and N-Methyl-2-pyrrolidone (NMP) casting solutions with water as coagulant via non-solvent induced phase inversion. The compatibility of the blend system was investigated through thermodynamic studies while membrane formation was determined using the cloud point techni...

Evolufion from TD-SCDMA to TD-LTE

This paper gives the brief introduction to key features of TD-SCDMA and TD-LTE (TDD Long Term Evolution). For the TD-SCDMA system, key technologies such as joint detection, smart antenna and synchronization are described and analyzed. For the TD-LTE system, important technologies such as OFDM, MIMO, uplink timing control, inter-cell interference coordination are applied. It is shown that the TD...

Pes Planus (Flat Feet)

Pes planus is the loss of the medial longitudinal arch of the foot. It can be flexible or rigid and it results in relative flattening of the plantar surface. The condition may be lifelong, or acquired through time, inflammation or other musculoskeletal problems. Treatment is generally only needed if the condition is new, painful or progressing, or when there is a fixed deformity or other associ...
