In this task, you are given the abstract of a research paper. Your task is to generate a summary of this abstract. Your summary should not be very short, but it's better if it's not more than 30 words.

Ex Input:
Learning in environments with large state and action spaces, and sparse rewards, can hinder a Reinforcement Learning (RL) agent's learning through trial-and-error. For instance, following natural language instructions on the Web (such as booking a flight ticket) leads to RL settings where input vocabulary and number of actionable elements on a page can grow very large. Even though recent approaches improve the success rate on relatively simple environments with the help of human demonstrations to guide the exploration, they still fail in environments where the set of possible instructions can reach millions. We approach the aforementioned problems from a different perspective and propose guided RL approaches that can generate unbounded amount of experience for an agent to learn from. Instead of learning from a complicated instruction with a large vocabulary, we decompose it into multiple sub-instructions and schedule a curriculum in which an agent is tasked with a gradually increasing subset of these relatively easier sub-instructions. In addition, when the expert demonstrations are not available, we propose a novel meta-learning framework that generates new instruction following tasks and trains the agent more effectively. We train DQN, deep reinforcement learning agent, with Q-value function approximated with a novel QWeb neural network architecture on these smaller, synthetic instructions. We evaluate the ability of our agent to generalize to new instructions onWorld of Bits benchmark, on forms with up to 100 elements, supporting 14 million possible instructions. The QWeb agent outperforms the baseline without using any human demonstration achieving 100% success rate on several difficult environments.

Ex Output:
We train reinforcement learning policies using reward augmentation, curriculum learning, and meta-learning to successfully navigate web pages.

Ex Input:
As our experience shows, humans can learn and deploy a myriad of different skills to tackle the situations they encounter daily. Neural networks, in contrast, have a fixed memory capacity that prevents them from learning more than a few sets of skills before starting to forget them.
In this work, we make a step to bridge neural networks with human-like learning capabilities. For this, we propose a model with a growing and open-bounded memory capacity that can be accessed based on the model's current demands. To test this system, we introduce a continual learning task based on language modelling where the model is exposed to multiple languages and domains in sequence, without providing any explicit signal on the type of input it is currently dealing with. The proposed system exhibits improved adaptation skills in that it can recover faster than comparable baselines after a switch in the input language or domain.

Ex Output:
We introduce a continual learning setup based on language modelling where no explicit task segmentation signal is given and propose a neural network model with growing long term memory to tackle it.

Ex Input:
This paper revisits the problem of sequence modeling using convolutional
architectures. Although both convolutional and recurrent architectures have a
long history in sequence prediction, the current "default" mindset in much of
the deep learning community is that generic sequence modeling is best handled
using recurrent networks. The goal of this paper is to question this assumption .
Specifically, we consider a simple generic temporal convolution network (TCN ),
which adopts features from modern ConvNet architectures such as a dilations and
residual connections. We show that on a variety of sequence modeling tasks ,
including many frequently used as benchmarks for evaluating recurrent networks ,
the TCN outperforms baseline RNN methods (LSTMs, GRUs, and vanilla RNNs) and
sometimes even highly specialized approaches. We further show that the
potential "infinite memory" advantage that RNNs have over TCNs is largely
absent in practice: TCNs indeed exhibit longer effective history sizes than their
recurrent counterparts. As a whole, we argue that it may be time to (re)consider
ConvNets as the default "go to" architecture for sequence modeling.

Ex Output:
We argue that convolutional networks should be considered the default starting point for sequence modeling tasks.
