39
+
40
+ "Derivative Works" shall mean any work, whether in Source or Object
41
+ form, that is based on (or derived from) the Work and for which the
42
+ editorial revisions, annotations, elaborations, or other modifications
43
+ represent, as a whole, an original work of authorship. For the purposes
44
+ of this License, Derivative Works shall not include works that remain

46
+ the Work and Derivative Works thereof.
47
+
48
+ "Contribution" shall mean any work of authorship, including

+ designated in writing by the copyright owner as "Not a Contribution."
61
+
62
+ "Contributor" shall mean Licensor and any individual or Legal Entity

66
+ 2. Grant of Copyright License. Subject to the terms and conditions of
67
+ this License, each Contributor hereby grants to You a perpetual,
68
+ worldwide, non-exclusive, no-charge, royalty-free, irrevocable

+ Contribution(s) with the Work to which such Contribution(s) was
81
+ submitted. If You institute patent litigation against any entity
82
+ (including a cross-claim or counterclaim in a lawsuit) alleging that

+ the Work or a Contribution incorporated within the Work constitutes
84
+ direct or contributory patent infringement, then any patent licenses
85
+ granted to You under this License for that Work shall terminate as of

+ do not modify the License. You may add Your own attribution
117
+ notices within Derivative Works that You distribute, alongside
118
+ or as an addendum to the NOTICE text from the Work, provided
119
+ that such additional attribution notices cannot be construed
120
+ as modifying the License.
121
+
122
+ You may add Your own copyright statement to Your modifications and
123
+ may provide additional or different license terms and conditions
124
+ for use, reproduction, or distribution of Your modifications, or
125
+ for any such Derivative Works as a whole, provided Your use,
126
+ reproduction, and distribution of the Work otherwise complies with
127
+ the conditions stated in this License.
128
+
129
+ 5. Submission of Contributions. Unless You explicitly state otherwise,
130
+ any Contribution intentionally submitted for inclusion in the Work
131
+ by You to the Licensor shall be under the terms and conditions of
132
+ this License, without any additional terms or conditions.
133
+ Notwithstanding the above, nothing herein shall supersede or modify
134
+ the terms of any separate license agreement you may have executed
135
+ with Licensor regarding such Contributions.
136
+
137
+ 6. Trademarks. This License does not grant permission to use the trade
138
+ names, trademarks, service marks, or product names of the Licensor,
139
+ except as required for reasonable and customary use in describing the
140
+ origin of the Work and reproducing the content of the NOTICE file.
141
+
142
+ 7. Disclaimer of Warranty. Unless required by applicable law or
143
+ agreed to in writing, Licensor provides the Work on an "AS IS" BASIS,
144
+ WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
145
+ implied, including, without limitation, any warranties or conditions
146
+ of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
147
+ PARTICULAR PURPOSE. You are solely responsible for determining the
148
+ appropriateness of using or redistributing the Work and assume any
149
+ risks associated with Your exercise of permissions under this License.
150
+
151
+ 8. Limitation of Liability. In no event and under no legal theory,
152
+ whether in tort (including negligence), contract, or otherwise,
153
+ unless required by applicable law (such as deliberate and grossly
154
+ negligent acts) or agreed to in writing, shall any Contributor be
155
+ liable to You for damages, including any direct, indirect, special,
156
+ incidental, or consequential damages of any character arising as a
157
+ result of this License or out of the use or inability to use the
158
+ Work (including but not limited to damages for loss of goodwill,
159
+ work stoppage, computer failure or malfunction, or any and all
160
+ other commercial damages or losses), even if such Contributor
161
+ has been advised of the possibility of such damages.
162
+
163
+ 9. Accepting Warranty or Additional Liability. While redistributing
164
+ the Work or Derivative Works thereof, You may choose to offer,
165
+ and charge a fee for, acceptance of support, warranty, indemnity,

+ # JNU-TSB
25
+
26
+ **JNU-TSB**는 한국어 뉴스와 주가 시계열을 함께 다루기 위한 교육용 **Time-LLM-style time-series bridge/router**입니다.
27
+
28
+ ```text
29
+ Repo ID: HONGRIZON/JNU-TSB
30
+ Full name: Jeju National University Time-Series Bridge
31
+ Nickname: TSB = Time-Series Bridge, also Time-Series Seungbin
32
+ Time-series model: amazon/chronos-2
33
+ Korean language model: EleutherAI/polyglot-ko-1.3b
34
+ Router: stock only, news only, news + stock hybrid
35
+ ```
36
+
37
+ 이 저장소는 **Chronos-2 또는 Polyglot-Ko의 가중치를 재배포하지 않습니다.** 여기에는 가벼운 wrapper 코드, 설정 파일, 예제 코드, 수업용 샘플 데이터만 포함되어 있습니다. 두 base model은 실행 시 Hugging Face에서 다운로드됩니다.
38
+
39
+ ## 이 저장소는 무엇인가요?
40
+
41
+ JNU-TSB는 **wrapper-style model repo**입니다. 학부생 수업 시연과 작은 연구 프로토타입을 위해 만들었으며, 한국어 금융 뉴스 제목을 일별 공변량으로 바꾸고 이를 Chronos-2에 전달하여 공변량 기반 시계열 예측을 수행합니다.
42
+
43
+ ```text
44
+ 뉴스 제목
45
+ -> Polyglot-Ko / keyword fallback
46
+ -> 일별 14차원 이벤트 공변량
47
+ -> Chronos-2 covariate-informed forecasting
48
+
49
+ 주가 시계열
50
+ -> Chronos-2 forecasting
51
+ ```
52
+
53
+ 이 구조는 **Time-LLM-style**입니다. 원 논문의 Time-LLM reprogramming architecture를 엄밀히 재구현한 것은 아닙니다. 의도적으로 숫자 시계열 예측은 Chronos-2가 담당하고, 한국어 LLM은 뉴스 텍스트를 구조화된 공변량으로 바꾸는 역할만 맡도록 설계했습니다.
54
+
55
+ ## 라우터 구조
56
+
57
+ JNU-TSB는 입력에 따라 세 가지 경로 중 하나를 자동 선택합니다.
58
+
59
+ | 입력 | 경로 | 출력 |
60
+ |---|---|---|
61
+ | `stock`만 있음 | Chronos-2 단독 경로 | 분위수 시계열 예측 |
62
+ | `news`만 있음 | Polyglot-Ko / keyword fallback 경로 | 이벤트 카테고리, 감성, confidence, 일별 공변량 |
63
+ | `stock` + `news` 모두 있음 | 하이브리드 경로 | 뉴스 공변량을 포함한 Chronos-2 예측 |
64
+
65
+ 하이브리드 경로는 다음 순서로 동작합니다.
66
+
67
+ ```text
68
+ 한국어 뉴스
69
+ -> 이벤트/감성 추출
70
+ -> 일별 14차원 covariate 생성
71
+ -> 주가 context dataframe과 merge
72
+ -> Chronos-2 predict_df 호출
73
+ -> forecast 반환
74
+ ```
75
+
76
+ ## 14차원 뉴스 공변량
77
+
78
+ 뉴스는 하루 단위로 집계되어 아래 14개 공변량으로 변환됩니다.
79
+
80
+ | 컬럼 | 의미 |
81
+ |---|---|
82
+ | `cov_earnings_count` | 실적/매출/영업이익 관련 뉴스 수 |
83
+ | `cov_product_count` | 제품 출시, 개발, 양산, 반도체 관련 뉴스 수 |
84
+ | `cov_macro_count` | 금리, 환율, 경기, 해외시장 등 거시경제 뉴스 수 |
85
+ | `cov_regulation_count` | 규제, 소송, 제재, 정부 정책 관련 뉴스 수 |
86
+ | `cov_supply_chain_count` | 공급망, 수주, 계약, 생산, 물류 관련 뉴스 수 |
87
+ | `cov_competition_count` | 경쟁사, 점유율, 가격 경쟁 관련 뉴스 수 |
88
+ | `cov_other_count` | 위 범주에 명확히 속하지 않는 뉴스 수 |
89
+ | `cov_sentiment_pos_count` | 긍정 감성 뉴스 수 |
90
+ | `cov_sentiment_neg_count` | 부정 감성 뉴스 수 |
91
+ | `cov_sentiment_neu_count` | 중립 감성 뉴스 수 |
92
+ | `cov_news_count` | 해당 날짜의 전체 뉴스 수 |
93
+ | `cov_sentiment_mean` | 평균 감성 점수, `-1`, `0`, `1` 기반 |
94
+ | `cov_confidence_mean` | 평균 추출 confidence |
95
+ | `cov_event_score` | 감성 × confidence의 합 |
96
+
97
+ ## 설치
98
+
99
+ ```bash
100
+ pip install -U transformers torch accelerate pandas pyarrow chronos-forecasting
101
+ ```
102
+
103
+ R에서 사용할 경우 `reticulate` 가상환경에 위 Python 패키지를 설치하면 됩니다. 예시는 `examples/r_quickstart.R`에 들어 있습니다.
104
+
105
+ ## Python 빠른 시작
106
+
107
+ 수업에서 빠르게 테스트할 때는 `use_llm_extractor=False`를 권장합니다. 이 경우 Polyglot-Ko를 로드하지 않고 keyword fallback만 사용하므로 훨씬 가볍게 실행됩니다.

181

202
+
203
+ ## 입력 형식
204
+
205
+ ### `stock`
206
+
207
+ `stock`은 pandas DataFrame, list of dicts, 또는 dict of columns 형식으로 넣을 수 있습니다. 최소 컬럼은 다음 두 개입니다.
208
+
209
+ ```text
210
+ timestamp: 날짜 또는 시간
211
+ target: 예측 대상 값, 예: 종가
212
+ ```
213
+
214
+ `item_id`가 없으면 내부적으로 `series_0`이 자동 부여됩니다.
215
+
216
+ ### `news`
217
+
218
+ `news`는 list of dicts 형식입니다. 각 항목은 최소한 날짜와 제목을 가져야 합니다.
219
+
220
+ ```json
221
+ [
222
+ {"date": "2024-12-01", "title": "삼성전자 HBM 신제품 출시"},
223
+ {"date": "2024-12-02", "title": "반도체 업황 둔화 우려"}
224
+ ]
225
+ ```
226
+
227
+ `title` 대신 `headline`, `text`, `content`도 인식합니다.
228
+
229
+ ### `future_news`와 `future_covariates`
230
+
231
+ 미래에 이미 알려진 뉴스나 일정이 있을 때만 `future_news` 또는 `future_covariates`를 사용하세요. 일반 뉴스 데이터는 보통 미래 값을 알 수 없으므로, 과거 뉴스는 context 구간의 past covariate로만 쓰는 것이 안전합니다.

233
+ ## Hugging Face 업로드 방법
234
+
235
+ 이 폴더의 **내용물 전체**를 `HONGRIZON/JNU-TSB` repo의 루트에 업로드하면 됩니다.
236
+
237
+ ```bash
238
+ pip install -U huggingface_hub
239
+ hf auth login
240
+ hf upload HONGRIZON/JNU-TSB . .
241
+ ```
242
+
243
+ 또는 포함된 스크립트를 사용할 수 있습니다.
244
+
245
+ ```bash
246
+ python upload_model_repo.py --repo_id HONGRIZON/JNU-TSB
247
+ ```
248
+
249
+ 다음은 업로드하지 마세요.
250
+
251
+ ```text
252
+ .venv/
253
+ venv/

259
+ Chronos-2 가중치
260
+ Polyglot-Ko 가중치
261
+ ```
262
+
263
+ ## 수업용 권장 사용법
264
+
265
+ 수업 시연에서는 다음 순서를 추천합니다.
266
+
267
+ 1. `news`만 넣어서 이벤트/감성/공변량이 어떻게 만들어지는지 확인합니다.
268
+ 2. `stock`만 넣어서 Chronos-2 시계열 예측 경로를 확인합니다.
269
+ 3. `stock + news`를 함께 넣어서 하이브리드 라우터가 동작하는지 확인합니다.
270
+ 4. `use_llm_extractor=False`와 `True`의 차이를 비교합니다.
271
+
272
+ `use_llm_extractor=True`는 Polyglot-Ko-1.3B를 로드하므로 CPU 환경에서는 느릴 수 있습니다. 학부생 실습에서는 fallback 모드부터 시작하는 편이 좋습니다.
273
+
274
+ ## 중요한 주의사항
275
+
276
+ - 이 모델은 교육/연구 데모용입니다. 투자 조언이나 실제 매매 판단에 사용하지 마세요.
277
+ - `EleutherAI/polyglot-ko-1.3b`는 instruction-tuned JSON extractor가 아니라 base language model입니다. 따라서 JSON 추출이 실패할 수 있고, 이 저장소는 keyword fallback을 함께 제공합니다.
278
+ - Chronos-2 또는 Polyglot-Ko 가중치를 이 저장소에 포함하지 않습니다. 실행 시 각 upstream repo에서 다운로드합니다.
279
+ - 이 저장소는 원 논문 Time-LLM을 그대로 재구현한 것이 아니라, 한국어 뉴스와 시계열 예측을 연결하는 Time-LLM-style wrapper/router입니다.
280
+
281
+ ## 라이선스
282
+
283
+ Wrapper 코드는 Apache-2.0으로 배포됩니다. Upstream base model인 `amazon/chronos-2`와 `EleutherAI/polyglot-ko-1.3b`는 각 Hugging Face repo의 라이선스와 사용 조건을 따릅니다.
