A Survey on Negative Transfer

Transfer learning(TL)utilizes data or knowledge from one or more source domains to facilitate learning in a target domain.It is particularly useful when the target domain has very few or no labeled data,due to annotation expense,privacy concerns,etc.Unfortunately,the effectiveness of TL is not always guaranteed.Negative transfer(NT),i.e.,leveraging source domain data/knowledge undesirably reduces learning performance in the target domain,and has been a long-standing and challenging problem in TL.Various approaches have been proposed in the literature to address this issue.However,there does not exist a systematic survey.This paper fills this gap,by first introducing the definition of NT and its causes,and reviewing over fifty representative approaches for overcoming NT,which fall into three categories:domain similarity estimation,safe transfer,and NT mitigation.Many areas,including computer vision,bioinformatics,natural language processing,recommender systems,and robotics,that use NT mitigation strategies to facilitate positive transfers,are also reviewed.Finally,we give guidelines on NT task construction and baseline algorithms,benchmark existing TL and NT mitigation approaches on three NT-specific datasets,and point out challenges and future research directions.To ensure reproducibility,our code is publicized at https://github.com/chamwen/NT-Benchmark.

Selective and Adaptive Incremental Transfer Learning with Multiple Datasets for Machine Fault Diagnosis

The visions of Industry 4.0 and 5.0 have reinforced the industrial environment.They have also made artificial intelligence incorporated as a major facilitator.Diagnosing machine faults has become a solid foundation for automatically recognizing machine failure,and thus timely maintenance can ensure safe operations.Transfer learning is a promising solution that can enhance the machine fault diagnosis model by borrowing pre-trained knowledge from the source model and applying it to the target model,which typically involves two datasets.In response to the availability of multiple datasets,this paper proposes using selective and adaptive incremental transfer learning(SA-ITL),which fuses three algorithms,namely,the hybrid selective algorithm,the transferability enhancement algorithm,and the incremental transfer learning algorithm.It is a selective algorithm that enables selecting and ordering appropriate datasets for transfer learning and selecting useful knowledge to avoid negative transfer.The algorithm also adaptively adjusts the portion of training data to balance the learning rate and training time.The proposed algorithm is evaluated and analyzed using ten benchmark datasets.Compared with other algorithms from existing works,SA-ITL improves the accuracy of all datasets.Ablation studies present the accuracy enhancements of the SA-ITL,including the hybrid selective algorithm(1.22%-3.82%),transferability enhancement algorithm(1.91%-4.15%),and incremental transfer learning algorithm(0.605%-2.68%).These also show the benefits of enhancing the target model with heterogeneous image datasets that widen the range of domain selection between source and target domains.

Pragmatic Failure In Intercultural Communication Based on Negative Transfer

In recent years, with the fast development of economy, international trade makes the communication constantly hap pen between people who come from different cultural backgrounds. Generally, the cultural difference may interrupt the commu nication and cause the failure of communication. A communicator, who is affected by his native culture, sometimes cannot under stand the foreigners' intention or express himself exactly in foreign language. Then, it is pragmatic failure. The thesis is to search the ways to solve the problem by analyzing the pragmatic failure.

A Brief Introduction to the Impact of the Negative Transfer of Mother Tongue on International Business Letter Writing and Countermeasures

Due to the impact of the negative transfer of mother tongue,students often think in their mother tongue when they write international business letters.Consequently,they may have difficulties communicating with the intended customers.In a bid to improve students'skills in international business letter writing,this article analyzes the impact of the negative transfer from three aspects:the word order in English,the position of modifiers and the use of conjunctions.

Studies of negative pragmatic transfer in interlanguage pragmatics

Negative pragmatic transfer (NPT) is nothing but a difference of saying things between non native speakers and native speakers. It occupies an important position in interlanguage pragmatics whose mission is to scrutinize how non native speakers do things with words with L2. This paper reported that 4 NPT related aspects have been heavily documented in the current literature: 1) L1 negative pragmatic transfers at the speech act level; 2) the distinction between negative pragmalinguistic and sociopragmatic transfers; 3) conditions of negative pragmatic transfers; and 4) native speaker’s attitudes towards L1 negative pragmatic transfers. Consequently, issues for future studies are also raised.

Negative inductive effect enhances charge transfer driving in sulfonic acid functionalized graphitic carbon nitride with efficient visible-light photocatalytic performance

Efficient photogenerated carrier migration/separation plays a critical role in increasing the photocatalytic performance of g-C_(3)N_(4).Herein,sulfonic acid group-functionalized g-C_(3)N_(4)(SACN)was synthesized and then synchronously strengthened by a facile-solid-state thermal reaction of g-C_(3)N_(4)and sulfamic acid.As a solid strong acid,sulfamic acid can be used to achieve acid etching on the surface of g-C_(3)N_(4)with the assistance of thermal treatment,leading to an enlarged specific surface area and increased surface catalytic reaction sites.More importantly,our experiments and density functional theory calculations indicate that the driving force generated by the negative inductive effect of sulfonic acid groups significantly improves the charge transfer dynamics and effectively inhibits their recombination.Moreover,the negative inductive effect can induce charge redistribution,which reduces the conduction band potential of g-C_(3)N_(4)to enhance the reduction ability of photo-induced electrons.As a result,the SACN-400 sample showed excellent photocatalytic performance in H2 generation with an apparent quantum efficiency of 11.03%at 420±15 nm,as well as an efficient photodegradation rate for organic pollutants.

Discussion on Negative Transfer of Chinese on Senior School Students' Writing

There commonly exists a phenomenon of negative transfer of Chinese in our students' English writing. Grammar, vocabulary, and expression are marked by the interference of Chinese which greatly impedes the improvement of the students' writing communicative competence. This is mainly due to the inadequacy of the students' language input. In view of the present situation, this paper aims to analyze some typical errors that the senior school students (Grade l)make in their writing so as to reveal the tact that during the process of second language acquisition, learners tend to transfer some of their Ll features into the target language in the field of phonetic, vocabulary, especially in the field of grammar. Therefore. the study of the Ll transfer and the error analysis are crucial in the research of the writing of a L2 and it plays an important role in the teaching and learning of a L2.

Chinese Students'Negative L1 Transfer in English Writing

Numerous researchers have studied the influence of L1 on the L2 composing process and consistently revealed that L2 writers may revert to their L1 when composing in L2(Cumming, 1989; Ellis, 2006;).The employment of L1 in L2 writing generally results in either facilitation(positive transfer) or impediment(negative transfer). The aim of this study is to investigate the specific errors and problems resulting from L1 interference within Chinese L2 writing and find possible solutions to minimize the negative effects of L1. In this respect, the focus of this paper is mainly on negative L1 transfer. Previous researches in this field have concentrated on how Chinese interfered L2 composing across different L2 proficiency levels or among different writing tasks. However, few studies have been carried out to analyze the details of how Chinese interfered with the students' English writing. This paper will conduct detailed analysis on the major negative transfer of L1 in terms of linguistic competence(from lexical, grammatical and syntactical level) and composing strategies(indirectness and organization style). The study will address and attempt to provide pedagogical suggestions for English writing instructors who particularly deal with Chinese L2 writers. The findings of the study has general applicability and will provide guidance for the teaching of L2 writing in other EFL/ESL settings.

Some Differences Between English and Chinese and the Negative Transfer of Mother Tongue in EFL Learning

The paper discusses 3 significant differences between Chinese and English. It proposes that because of the differences, the transfer of mother tongue into the target language tends to appear in the negative form. The negative transfer of Chinese into English is the major cause of the so-called Chinglish. The paper states some forms of the negative transfer.

The Negative Transfer of Mother Tongue on English Pronunciation——from the Phonetic and Phonological Perspectives

Language researchers have long been working on the language transfer theory since 1970s with an aim to help second language acquisition. Researches on transfer of pronunciation were explored from many aspects, such as phonetics, age, motivation and culture etc. By illustrating the Chinese learners' improper English pronunciation, it tries to discuss the negative transfer of their mother tongue on the English pronunciation on the theoretical basis of phonetic and phonological differences between the two languages. Based on these studies and analysis, it hopes to arouse the learners' awareness of the different pronunciation between English and Chinese and their interests in acquiring a native-like pronunciation, and hopefully the teachers will also help the learners have a good knowledge of the difference before they're affected by the negative transfer of Chinese.
