Knowledge-Augmented Language Model Verification

Recent Language Models (LMs) have shown impressive capabilities in generating texts with the knowledge internalized in parameters. Yet, LMs often generate the factually incorrect responses to the given queries, since their knowledge may be inaccurate, incomplete, and outdated. To address this problem, previous works propose to augment LMs with the knowledge retrieved from an external knowledge source. However, such approaches often show suboptimal text generation performance due to two reasons: 1) the model may fail to retrieve the knowledge relevant to the given query, or 2) the model may not faithfully reflect the retrieved knowledge in the generated text. To overcome these, we propose to verify the output and the knowledge of the knowledge-augmented LMs with a separate verifier, which is a small LM that is trained to detect those two types of errors through instruction-finetuning. Then, when the verifier recognizes an error, we can rectify it by either retrieving new knowledge or generating new text. Further, we use an ensemble of the outputs from different instructions with a single verifier to enhance the reliability of the verification processes. We validate the effectiveness of the proposed verification steps on multiple question answering benchmarks, whose results show that the proposed verifier effectively identifies retrieval and generation errors, allowing LMs to provide more factually correct outputs.

The first Irish genome and ways of improving sequence accuracy

Whole-genome sequencing of an Irish person reveals hundreds of thousands of novel genomic variants. Imputation using previous known information improves the accuracy of low-read-depth sequencing

Industrialisasi Berbasis Pertanian sebagai Grand Stratedy Pembangunan Ekonomi Nasional

EnglishAs a developing economy Indonesia, should have a comprehensive integrated long-term development plan which may be used as the guideline in implementing its national economic development as well as an instrument for evaluating government accountability and credibility. The New Order regime had prepared its first and second long-term development plan for 1969-1993 and 1993-2018 successively. The twin plans, however, has led Indonesia to the 1997-1999 multi dimensions crises and is considered in appropriate in the existing new era of total reformation. It must be totally reconstructed. For this, public discussions on the need for the government to formulated the new grand strategy of national development have emerged, but up and down, in the last two years. As an active contribution to the public debase, this paper reviews previous, Indonesia development plans, others\u27 countries experiences as well as grand theories of economic development. Then it is suggested that the agricultural based industrialization may be the most suitable one for Indonesia. The new grand strategy should be decided based on a national concensus in order to avoid the practice of just for political rhetoric\u27s as was during the New Order regime. IndonesianBagi negara berkembang seperti Indonesia, rencana pembangunan jangka panjang komprehensif-integratif sangat di perlukan sebagai acuan pelaksanaan pembangunan dan sebagai salah satu instrumen akuntabilitas dan kredibilitas pemerintah. Pemerintahaan Orde Baru telah menyusun rancangan pembangunan jangka panjang tahap I dan II masing-masing untuk peiode 1969-1993 dan 1993-2018. Rencana jangka panjang yang disusun rejim Orde Baru tersebut terbukti membawa Indonesia kedalam krisis tahun 1997-1999 dan sudah tidak sesuai dalam era Reformasi sehingga perlu dirancang ulang. Dalam dua tahun terakhir sesungguhnya telah muncul wacana publik yang menuntut agar pemerintah segera menyusun grand strategy ( strategi besar ) pembangunan nasional. Sebagai bagian dari wacana tersebut, tulisan ini mereview tentang konsepsi strategi pembangunan selama Orde Baru, pengalaman beberapa negara lain pemikiran teoritis tentang strategi pembangunan ekonomi. Berdasarkan hasil review tersebut, disarankan agar industrialisasi berbasis pertanian (agricultural based industrialization) dijadikan sebagai strategi besar (grand strategy) pembangunan nasional. Strategi tersebut haruslah dijadikan sebagai konsensus nasional, sehingga tidak sekedar retorika politik seperti pada masa Orde Baru

A genome-wide Asian genetic map and ethnic comparison: The GENDISCAN study

<p>Abstract</p> <p>Background</p> <p>Genetic maps provide specific positions of genetic markers, which are required for performing genetic studies. Linkage analyses of Asian families have been performed with Caucasian genetic maps, since appropriate genetic maps of Asians were not available. Different ethnic groups may have different recombination rates as a result of genomic variations, which would generate misspecification of the genetic map and reduce the power of linkage analyses.</p> <p>Results</p> <p>We constructed the genetic map of a Mongolian population in Asia with CRIMAP software. This new map, called the GENDISCAN map, is based on genotype data collected from 1026 individuals of 73 large Mongolian families, and includes 1790 total and 1500 observable meioses. The GENDISCAN map provides sex-averaged and sex-specific genetic positions of 1039 microsatellite markers in Kosambi centimorgans (cM) with physical positions. We also determined 95% confidence intervals of genetic distances of the adjacent marker intervals.</p> <p>Genetic lengths of the whole genome, chromosomes and adjacent marker intervals are compared with those of Rutgers Map v.2, which was constructed based on Caucasian populations (Centre d'Etudes du Polymorphisme Humain (CEPH) and Icelandic families) by mapping methods identical to those of the GENDISCAN map, CRIMAP software and the Kosambi map function. Mongolians showed approximately 1.9 fewer recombinations per meiosis than Caucasians. As a result, genetic lengths of the whole genome and chromosomes of the GENDISCAN map are shorter than those of Rutgers Map v.2. Thirty-eight marker intervals differed significantly between the Mongolian and Caucasian genetic maps.</p> <p>Conclusion</p> <p>The new GENDISCAN map is applicable to the genetic study of Asian populations. Differences in the genetic distances between the GENDISCAN and Caucasian maps could facilitate elucidation of genomic variations between different ethnic groups.</p

Unusual Cause of Acute Right Ventricular Dysfunction: Rapid Progression of Superior Vena Cava Aneurysm Complicated by Thrombosis and Pulmonary Thromboembolism

Aneurysms of the major thoracic veins are rare. They are usually asymptomatic and thus treated conservatively. We report an extremely rare case of rapidly progressing superior vena cava (SVC) aneurysm complicated by thrombosis and acute pulmonary thromboembolism (PTE) with right ventricular dysfunction. Thrombolytic therapy for hemodynamically significant acute PTE was harmful to the patient in the present case, because it induced further thrombosis and mobilization of the thrombi within the aneurysm, subsequently causing de novo PTE. Surgical aneurysmectomy combined with pulmonary artery embolectomy would be a treatment of choice in patients with SVC aneurysm complicated by acute PTE
