+### Paper
+
+Title: Towards ai-complete question answering: A set of prerequisite toy tasks
+Abstract: https://arxiv.org/abs/1502.05698
+
+One long-term goal of machine learning research is to produce methods that are applicable to reasoning and natural language, in particular building an intelligent dialogue agent. To measure progress towards that goal, we argue for the usefulness of a set of proxy tasks that evaluate reading comprehension via question answering. Our tasks measure understanding in several ways: whether a system is able to answer questions via chaining facts, simple induction, deduction and many more. The tasks are designed to be prerequisites for any system that aims to be capable of conversing with a human. We believe many existing learning systems can currently not solve them, and hence our aim is to classify these tasks into skill sets, so that researchers can identify (and then rectify) the failings of their systems. We also extend and improve the recently introduced Memory Networks model, and show it is able to solve some, but not all, of the tasks.

+Title: `BLiMP: A Benchmark of Linguistic Minimal Pairs for English`
+Abstract: `https://arxiv.org/abs/1912.00582`
+
+BLiMP is a challenge set for evaluating what language models (LMs) know about
+major grammatical phenomena in English. BLiMP consists of 67 sub-datasets, each
+containing 1000 minimal pairs isolating specific contrasts in syntax, morphology,
+or semantics. The data is automatically generated according to expert-crafted
+grammars.

BLiMP consists of 67 individual datasets, each containing 1,000 minimal pairs—that is, pairs of minimally different sentences that contrast in grammatical acceptability and isolate specific phenomenon in syntax, morphology, or semantics. We generate the data according to linguist-crafted grammar templates, and human aggregate agreement with the labels is 96.4\%. We evaluate n-gram, LSTM, and Transformer (GPT-2 and Transformer-XL) LMs by observing whether they assign a higher probability to the acceptable sentence in each minimal pair. We find that state-of-the-art models identify morphological contrasts related to agreement reliably, but they struggle with some subtle semantic and syntactic phenomena, such as negative polarity items and extraction islands. }

+# ETHICS Dataset

+
+Pointer Sentinel Mixture Models
+https://arxiv.org/pdf/1609.07843.pdf
+
+The ETHICS dataset is a benchmark that spans concepts in justice, well-being,
+duties, virtues, and commonsense morality. Models predict widespread moral
+judgments about diverse text scenarios. This requires connecting physical and
+social world knowledge to value judgements, a capability that may enable us
+to steer chatbot outputs or eventually regularize open-ended reinforcement
+learning agents.

+# WinoGrande
+
+### Paper
+
+Title: `WinoGrande: An Adversarial Winograd Schema Challenge at Scale`
+
+Abstract: https://arxiv.org/abs/1907.10641
+
+WinoGrande is a collection of 44k problems, inspired by Winograd Schema Challenge
+(Levesque, Davis, and Morgenstern 2011), but adjusted to improve the scale and
+robustness against the dataset-specific bias. Formulated as a fill-in-a-blank
+task with binary options, the goal is to choose the right option for a given
+sentence which requires commonsense reasoning.
+
+NOTE: This evaluation of Winogrande uses partial evaluation as described by
+Trinh & Le in Simple Method for Commonsense Reasoning (2018).
